React-native: “xcodebuild” command but it exited with error code 65

[ldco2016]

After upgrading to React Native 0.59.9 and React 16.8.3 and attempted to run react-native run-ios, I get this error:

Steps To Reproduce

1. Run react-native run-ios

Describe what you expected to happen:

Well, since I did upgrade I had expected some bugs, but I am unfamiliar with the inner workings of Xcode in conjunction with React Native.

Snack, code example, or link to a repository:

https://www.dropbox.com/s/ygyrhnno8aou4jg/RNsampleApp.zip?dl=0

I was eventually able to resolve the above error by following this guide:

https://stackoverflow.com/questions/54515175/undefined-symbols-for-architecture-arm64-jsclasscreate

and running react-native link.

However, now inside of Metro Bundler I get this error:

VM16:1 GET http://localhost:8081/Users/danale/Library/Developer/CoreSimulator/Devices/9E045643-4D13-41F4-A144-781A6513E884/data/Containers/Bundle/Application/AC51BEE9-3B17-4246-A747-D9D47B460B58/NFIBEngage.app/main.jsbundle 404 (Not Found)

getBlobUrl @ (index):209
ws.onmessage @ (index):184
(index):190 Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0

I am not exactly sure what is going on there, but its referencing a line of code found inside of ios/NFIBEngage.xcodeproj/project.pbxproj:

/* Begin PBXFileReference section */
        008F07F21AC5B25A0029DE68 /* main.jsbundle */ = {isa = PBXFileReference; fileEncoding = 4; lastKnownFileType = text; path = main.jsbundle; sourceTree = "<group>"; };

13B07FAE1A68108700A75B9A /* NFIBEngage */ = {
            isa = PBXGroup;
            children = (
                6B2F5E9F2007D4B500FF4B14 /* UA.entitlements */,
                6B2F5E9E2007D4AC00FF4B14 /* QA.entitlements */,
                6B2F5E9D2007D49F00FF4B14 /* DEV.entitlements */,

                008F07F21AC5B25A0029DE68 /* main.jsbundle */,

When I attempt a react-native run-ios a second time, I still get a successful build in Xcode but with this error:

info ** BUILD SUCCEEDED **


info Installing build/NFIBEngage/Build/Products/Debug-iphonesimulator/NFIBEngage.app
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=164):

error Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/NFIBEngage/Build/Products/Debug-iphonesimulator/NFIBEngage.app/Info.plist

and when I attempt to open the app in the Simulator, it does not boot up and in debugger-ui I get this error:

VM16:1 GET http://localhost:8081/Users/danale/Library/Developer/CoreSimulator/Devices/9E045643-4D13-41F4-A144-781A6513E884/data/Containers/Bundle/Application/AC51BEE9-3B17-4246-A747-D9D47B460B58/NFIBEngage.app/main.jsbundle 404 (Not Found)

It gets to the splash screen with the above error and immediately crashes. I then tried adding this script:

"build:ios": "react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/NFIBEngage/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'", but instead of fixing the issue I got this error:

npm run build:ios

Then I tried booting up the application via Xcode and it boots up the simulator and attempts to open the application inside of simulator but it hangs on splash screen and Xcode gave me this error:

error: EOF while parsing a value at line 1 column 0

Add --log-level=[info|debug] or export SENTRY_LOG_LEVEL=[info|debug] to see more output.
Please attach the full debug log to all bug reports.

and it also indicates this configuration inside of Xcode:

        NSDate* later = [NSDate dateWithTimeIntervalSinceNow:0.1];
        [[NSRunLoop mainRunLoop] runUntilDate:later]; Thread 1: signal SIGBART
    }
}

I am still stuck on this main.jsbundle not being found. Can anyone assist here?

i have the same error when i use react-native run-ios ， but in Xcode，click the run button ，everything is fine

[AlbertVilaCalvo]

I just got this error after upgrading to 0.60.4 (from 0.59.2).

To fix it I've had to rename the xcworkspace folder from gazella.xcworkspace to Gazella.xcworkspace.

I could successfully run the project from within XCode, but got the error when doing react-native run-ios on the terminal. Now everything works fine.

@AlbertVilaCalvo your solution is not working for me

[tusharmutreja]

Hey, I have the same error when I run react-native run-ios after upgrading the react-native version to 0.59.5.

And also Xcode not able to open the project.

Any Help?

[poojapmagar]

Facing same error is there any solution for this

[AdeelMughal]

Same issue. Any solution so far ?

[nicolas-rohricht]

Hi guys.
Did you find any solution for that?

[nicolas-rohricht]

I resolved my issue changing the Build Active Architecture Only to:

Debug >> Yes
Release >> No

On xCode, select your Project Target >> Build Settings >> Architetures >> Build Active Architecture Only.

After changing that, react-native run-ios was executed like a charm.

[tostavio]

Same problem here.

With xcode, app runs.
With react-native run-ios, don't.

[marciosalinodias]

Hey guys,
Same error.

I fixed just by changing the name from "AwesomeProject" to "awesomeproject"

Works for me ;)

[git-sid-go]

Hello! I faced this issue with React Native version 0.61.2 and this worked for me.
Navigate to the ios folder of the app and run the command pod install
Once that is done, go back to the root directory and run react-native run-ios

[vibdheeraj]

@git-sid-go thanx this solution work for me.

[azizuysal]

In your project folder:

cd ios
rm -rf build/
cd ..

Run react-native run-ios again.

[josemvcerqueira]

Make sure you open your /ios on xcode and go to workspace settings and set the build system to legacy

Hello! I faced this issue with React Native version 0.61.2 and this worked for me.

[valentinorusconi]

I am facing this problem with react native 0.59.10 and expo, is there any solution?

[iampeterbanjo]

i had the same issue and restarting my computer worked 🤷‍♂

[Ashutosh8127]

go inside ios folder in terminal
cd ios/
run pod install
after run react-native run-ios

[RupamShaw]

I just got this error after upgrading to 0.60.4 (from 0.59.2).

To fix it I've had to rename the xcworkspace folder from gazella.xcworkspace to Gazella.xcworkspace.

I could successfully run the project from within XCode, but got the error when doing react-native run-ios on the terminal. Now everything works fine.
worked for me by changing Uppercase both files .xcodeproj and .xcworkspace

[mvfsillva]

To solve this problem, I did something like @Ashutosh8127:

cd ios/
$ rm -rf build/
$ pod install
cd ..
$ npm run ios #or npx react-native run-ios

[shixiaoquan]

In your project folder:

cd ios
rm -rf build/
cd ..

Run react-native run-ios again.

It's worked for me tks

[diegotauchert]

I resolved my issue changing the Build Active Architecture Only to:

Debug >> Yes
Release >> No

On xCode, select your Project Target >> Build Settings >> Architetures >> Build Active Architecture Only.

After changing that, react-native run-ios was executed like a charm.

it worked for me... thanks 👍🏼

[engtom]

This may occur especially when you change the bundle ID, the provisioning profiles, create new targets etc. So only running pod install may not work. In this cases, we have to also remove the build folder, like @azizuysal said, executing this:

- cd ios
- rm -rf build/

After this everything should get back to normality.

[chacaa]

Try changing the Build System property from New Build System (Default) to Legacy Build System. You can do it from here File -> Workspace Settings. That change did the job for me, hope it helps you!

[kockok]

pod install

I got error code 65 after updating to the latest react-native,
the above steps worked.

[ayepRahman]

Hello! I faced this issue with React Native version 0.61.2 and this worked for me.

Work! great!

[danielkiesshau]

I had a "react-native" module installed globally. After I uninstalled it, I could start my project

[hsh2001]

(English is not my native language. Sorry for bad english.) I got the same error even I tried the way in the comments above. But when I reinstalled Cocoapods, I solved the problem! Try it.

cd ios;
rm -rf Pods;
rm -rf build; # may need sudo

sudo gem uninstall cocoapods;
sudo gem install cocoapods;

pod install;
cd ..;

[sjc5]

- cd ios
- rm -rf build/

After this everything should get back to normality.

This worked for me after also executing "pod install" in the ios folder. Not sure whether that step is prerequisite but thought I'd mention.

[Khushboo-gupta-123]

when i run my project on terminal i faced this issuue. is there any solution?
"Failed to build iOS project. We ran "xcodebuild" command but it exited with error code null. To debug build logs further, consider building your app with Xcode.app, by opening demo.xcworkspace "

[234146326]

My error !
error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening react_native_test1.xcworkspace. Run CLI with --verbose flag for more details.
My solution：
The “Metro Bundler terminal” running。After closing, run react-native run-ios. Success.

》Hope that can help！

[lucasR23]

I got the same error and in the folder of the project i had to run:

- yarn
- cd ios
- pod install

[GuilhermeTrivilin]

What worked for me was to rename the project by removing the special characters.

Example: "project_marketplace" to "projectmarketplace"

In this case, I redid the project with react-native init and copied the src and package.json folder.

[knudnilsen]

I had another progress running on port 8081. Just stopped that service and - et voila - works again

[guistrutzki]

i had the same issue and restarting my computer worked 🤷‍♂

I tried all the other solutions, but just this one worked. So ridiculous but thanks haha =D

[evelew]

I tried all the solutions, and after all I realized that I was trying to run the app at one port that was running an web application, after stop the web application the react native app runs normally...

Just double check it.

[shixiaoquan]

i had the same issue and restarting my computer worked man_shrugging

I tried all the other solutions, but just this one worked. So ridiculous but thanks haha =D

sometimes,restart is the best solution,

[joeponzio]

I had this issue and it was because I had renamed my XCode targets to Development and Production (and hence build schemes in XCode) which don't match my workspace/project name. npx react-native run-ios was looking for a target matching my workspace name, but that no longer existed. I solved this by specifying which scheme to use, which is not a hack or workaround but a reasonable parameter to add if you have multiple schemes:

npx react-native run-ios --scheme "Development"

After a minute of XCode rebuilding my project (through the command line, so you don't see a ton of progress), I am now up and running.

[markuskoehler360]

after reading the topmost answer in this thread, tried running it with xcode. there i could debug my errors. in my case i was running another builder on port 8081. the port react-native wants to use.
after killing this process, i was able to build my app using 'react-native run-ios'

i hope this helps anyone!

[markuskoehler360]

maybe you had the same issue as me, and restarting led to a free 8081 port!

[khanof89]

I was getting this error because I ran react-native link, removing the link
react-native unlink react-native-vector-icons
and then running react-native run-ios and everything worked fine

[tksilicon]

Hello! I faced this issue with React Native version 0.61.2 and this worked for me.
Navigate to the ios folder of the app and run the command pod install
Once that is done, go back to the root directory and run react-native run-ios

This helped. I do not know why they are downvoting it.

[sumanthyedoti]

I was getting this error because I ran react-native link, removing the link
react-native unlink react-native-vector-icons
and then running react-native run-ios and everything worked fine

The true reason 😄
Even rn-vector-icons installation guide says that linking automatically is not working well. Try other options

[wemboava]

go to an ios folder on the terminal
$ cd ios
install the pod
$ pod install
if you don't have cocoapods installed, run
$ brew install cocoapods
go back a folder
$ cd ..
and finally
$ react-native run-ios

[jeroen-van-dijk]

Make sure port 8081 is not in use.

lsof -i:8081

Fixed it for me

[Liqiankun]

• rm -rf node_modules
• rm -rf build
• yarn
• npx react-native run-ios

This works for me.

[GardEngen]

Hi guys, same problem from here.
I fixed it by running react-native unlink react-native-vector-icons, for some reason it doesn't work with that installation method

I got the same issue. I tried lots of different ways listed above. Didn't work for me.
I fixed by remove all .ttf lines in /ios/exampleApp.xcodeproj/project.pbxproj which listed in XCode when I build.
Hope it helps if other solutions does work.

Thanks for all the solutions everyone! The original issue seems to be a bit dated. Closing, please open a new issue if this occurs in the latest RN version and none of these solutions work.

I was getting this error because I ran react-native link, removing the link
react-native unlink react-native-vector-icons
and then running react-native run-ios and everything worked fine

This works for me. Thank's buddy

Hello! I faced this issue with React Native version 0.61.2 and this worked for me.
Navigate to the ios folder of the app and run the command pod install
Once that is done, go back to the root directory and run react-native run-ios

thanks. it really works for me ! so nice!!!!

In my case,

1. Clone repo
2. npm install
3. cd ios && pod install && cd ..

I was getting this error because I ran react-native link, removing the link
react-native unlink react-native-vector-icons
and then running react-native run-ios and everything worked fine

I use both react-native unlink react-native-vector-icons and cd ios && rm -rf build/.

1. The only way I took was cloning repo again by the time error codes popped up
2. Go to react-native-vector-icons GitHub
3. Follow the Installation steps.
   
   
   
   • I used iOS Option: Manually
   
   
4. Don't forget pod install in your project's root directory run cd ios && pod install && cd ..
5. react-native run-ios
