But if I use ns run android, it is working well

Same problem can't figure out why

[ChrisBates]

Same issue. Ubuntu 20.04, ns-cli version 7.1.2

Same issue - xubuntu 20.04. Do you guys also experience that live reload doesn't work on the android emulator?

[Benoye]

Same issue on macOS Big Sur on a M1 mac

EDIT : version of Node was the problem, I rolled back to 15.5.0 using nvm (dunno why I picked this version in particular) and it worked !

[rochadk]

I was using v14.15.5 (lts) and tried switching to 15.5.0 (what's up with all the deprecated packages when installing nativescript?) and still get the same response:

$ ns device

what's up with all the deprecated packages when installing nativescript?

When you npm i -g nativescript, npm often prints out a bunch of deprecated dependencies, these are generally hard to avoid since they are often transitive dependencies deeply nested in the dependency tree.

Some dependencies that are no longer maintained, we are replacing with newer alternatives, but this is not a simple process, as parts of the CLI require rewrites to support alternative dependencies. And keep in mind the CLI has been around since 2015.

(In any case, these are not really a security concern, since they are not exposed to the public (ie. not running on a public facing server), and are only used on the local machine during development, where most of the security concerns don't apply.)

As for the issue, I don't think ios-device-lib ever worked on linux - it's only compiled for win32 & darwin/x64 - in fact it shouldn't even be called, so that makes me curious why it's being called here. Can you open your global node_modules/nativescript/lib/common/mobile/mobile-core/devices-service.js (path could vary so just find where the cli's files are installed & find devices-service.js and look for getEmulatorImages( and add some console.logs - specifically interested about

console.log(this.$hostInfo.isDarwin)

https://github.com/NativeScript/nativescript-cli/blob/04202dcb8f828939205ccf58fb8121304e21d61a/lib/common/mobile/mobile-core/devices-service.ts#L157-L180

That would help us narrow it down - if it prints true - then the host detection is off & needs to be adjusted.

regarding node15 & npm7: see https://github.com/NativeScript/nativescript-cli/issues/5492

For those who just want to print available devices, you can use ns devices android - that should work (unable to test, as I don't currently have access to a linux machine)

Thank you for your comment!

$ nvm current
v15.5.0
$ cat .nvm/versions/node/v15.5.0/lib/node_modules/nativescript/lib/common/mobile/mobile-core/devices-service.js | grep getEmulatorImages -A 4 -m 1
    getEmulatorImages(options) {
        console.log('hits me');
        console.log(this.$hostInfo.isDarwin);
        return __awaiter(this, void 0, void 0, function* () {
            const result = Object.create(null);

Hmm, not quite what I expected - but looks like

is logged by devices-service.js -> initializeCore( which has a couple branches it could run.

Another possible clue would be to run ns devices --log trace, it may print a bit more info/traces.

[lowkeyboard]

hello here is my solution on linux mint 20:
npm i ios-device-lib
after this try again
ns device run
and it should run smoothly.

ps: i also connected and run a simple project from android-studio to make sure my device is connected.

also here is my versions:
`Angular CLI: 11.2.1
npm 6.14.11
node: 15.9.0
OS: Linux x64

Angular: 11.0.9
... animations, common, compiler, compiler-cli, core, forms
... platform-browser, platform-browser-dynamic, router
Ivy Workspace: Yes

Package Version

@angular-devkit/architect 0.1100.7
@angular-devkit/core 10.0.8
@angular-devkit/schematics 11.0.7
@ngtools/webpack 11.0.7
@schematics/angular 11.2.1 (cli-only)
@schematics/update 0.1102.1 (cli-only)
rxjs 6.6.3
typescript 4.0.7`

i hope this helps

I tried to switch to other node release but same result

[rigor789]

@j99ht for M1 a workaround until next release is

cp -R /opt/homebrew/lib/node_modules/nativescript/node_modules/ios-device-lib/bin/darwin/x64 /opt/homebrew/lib/node_modules/nativescript/node_modules/ios-device-lib/bin/darwin/arm64

This is just a workaround - by using rosetta 2 on the x64 binary - next release is compiled for arm64 directly and will not need the workaround.

[JBBailly]

in my case (Linux/Ubuntu 18.04 ) the workaround was to copy the "darwin" folder to a "linux folder"
cp -r /usr/lib/node_modules/nativescript/node_modules/ios-device-lib/bin/darwin/ /usr/lib/node_modules/nativescript/node_modules/ios-device-lib/bin/linux

[jcassidyav]

I'm seeing the same thing in windows, the issue in this case is that the path is incorrect (missing slash)
