React-native: Packager not starting after 0.59 to 0.60 migration

[jacargentina]

I've migrated my app from 0.59 to 0.60, and now somehow the "Start Packager" script in xcode is not running anything.

I've managed to get to the error which is Unable to find application named 'Apple_Terminal' Can't start packager automatically

Can't start packager automatically

[mrbrentkelly]

I'm seeing the same thing after upgrading from 0.59.10 to 0.60.2. The metro bundler is no longer started when running react-native run-ios or react-native run-android.

[rosiearms]

I am also having the same issue. The metro bundler doesn't start for ios or android after upgrading from 0.59.9 to 0.60.0.

[ravimaurya-nickelfox]

Facing same issue. The packager is running in iOS simulator but not running in android emulator or android device. The issue is after upgrading to 0.60. Created a new project with 0.60 and the issue still exists.

[ocano12]

Same Issue here. If I run react-native android metro doesnt boot up. I have to run react-native start then react-native run-android. However, If I run react-native ios metro pops boots up normally.

[wamry]

Same here, any updates ?

[jacargentina]

I've managed to know this (for iOS at least): the ios folder and its content must be migrated/updated in order to get the new Start Packager script, which is a build phase for xcodebuild. I've done it manually, by creating a new project like this:

1. My project is on /Users/myusername/git/myProject
2. cd /Users/myusername/
3. cp git/myProject/ios git/myProject/ios-backup
4. react-native init myProject
5. cp myProject/ios git/myProject/ios
6. Manually fix all missing things like resources, signing configurations, etc which are on git/myProject/ios-backup/myProject.xcodeproj
7. Do all steps related to react-native unlink when needed by the official migration to RN 0.60. Also maybe maintain some not yet prepared packages with react-native link
8. There should be much near a buildable RN 0.60+ migrated project

[wamry]

@jacargentina it doesn't matter, it works on ios, run the project from xcode.
The problem is in android.

[chc200]

Having this problem as well and continually get to where it says No bundle URL present any ideas how to get past this? No bundle popping up during build anymore either.

[firatciftci]

Make sure you have "Start Packager" as one of the items on the Build Phases tab inside your Xcode project. I was having the exact same problem and I figured it out by comparing my Build Phases tab to a brand new project created on version 0.60.4 through react-native init. If you don't see "Start Packager," create a new build phase and paste in the following code block:

export RCT_METRO_PORT="${RCT_METRO_PORT:=8081}"
echo "export RCT_METRO_PORT=${RCT_METRO_PORT}" > "${SRCROOT}/../node_modules/react-native/scripts/.packager.env"
if [ -z "${RCT_NO_LAUNCH_PACKAGER+xxx}" ] ; then
if nc -w 5 -z localhost ${RCT_METRO_PORT} ; then
if ! curl -s "http://localhost:${RCT_METRO_PORT}/status" | grep -q "packager-status:running" ; then
echo "Port ${RCT_METRO_PORT} already in use, packager is either not running or not running correctly"
exit 2
fi
else
open "$SRCROOT/../node_modules/react-native/scripts/launchPackager.command" || echo "Can't start packager automatically"
fi
fi

Next time you run react-native run-ios the packager should launch automatically.

[alixq]

export RCT_METRO_PORT="${RCT_METRO_PORT:=8081}"
echo "export RCT_METRO_PORT=${RCT_METRO_PORT}" > "${SRCROOT}/../node_modules/react-native/scripts/.packager.env"
if [ -z "${RCT_NO_LAUNCH_PACKAGER+xxx}" ] ; then
if nc -w 5 -z localhost ${RCT_METRO_PORT} ; then
if ! curl -s "http://localhost:${RCT_METRO_PORT}/status" | grep -q "packager-status:running" ; then
echo "Port ${RCT_METRO_PORT} already in use, packager is either not running or not running correctly"
exit 2
fi
else
open "$SRCROOT/../node_modules/react-native/scripts/launchPackager.command" || echo "Can't start packager automatically"
fi
fi

I did that at first and it did work OK but it would start the packager too late in the process and an error message would appear until I reloaded once the packager had finished bundling.

I would recommend once you have done this that you move your new build phase (hold and drag in Build Phases tab) in between [CP] Check Pods Manifest.lock and Compile Sources to reflect the order in newly generated projects (I checked). You can also rename it Start Packager for better clarity/consistency.
