Reproducible Demo

[Esemesek]

It seems like you have global react-native-cli installed, which causes name conflicts in react-native binary. Could you please remove global react-native-cli by running yarn global remove react-native-cli and try again with yarn react-native run-android?

[thymikee]

@Esemesek since we call npx, it's npm records we want to update, so running

npm uninstall -g react-native-cli

seems more appropriate.

[b1ngx]

@Esemesek

I haven't install react-native-cli any all. Create the app with npx react-native init.
And when i reinstall @react-native-community/cli-platform-android with @3.0.0-alpha.2 , it's ok.

[grabbou]

Can you please run yarn react-native config and paste the output? It's interesting, because on master, line 182 contains nothing but a function declaration.

I would recommend upgrading to "just released" version 3.0.0 and pasting the output again. The line should be different and we can debug this further.

[b1ngx]

I create the project use command npx react-native init test

Have you seen the error message?

Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/b1ng/rn/test' directory to output valid JSON, but it didn't.

[b1ngx]

I did not install react-native and react-native-cli , and i also run npm uninstall -g react-native react-native-cli

When remove the native_modules.gradle comment /* dir */

def reactNativeConfigOutput = this.getCommandOutput(command, /* dir */) 

to

def reactNativeConfigOutput = this.getCommandOutput(command, dir)

it's ok.

[bneigher]

I am seeing this after upgrading to 0.61.4 react-native. I've never installed react-native or react-native-cli globally. Commenting back in the 2nd argument here didn't change it for me

[grabbou]

Looks like the JSON is invalid and react-native config works w/o issues here. So, to verify, could you run npx --quiet --no-install react-native config yourself and tell us what's the output? The CLI clearly has issues parsing the configuration.

[sibelius]

I've solved like this on native_modules.gradle

- def command = "${npx} --quiet --no-install react-native config"
+ def command = "yarn --silent react-native config"
` ``

[rvgroup]

Try updating the Node to the version 10.17.0. It helped me.

[grabbou]

@sibelius thanks! I remember @thymikee was saying --quiet mode did have its issues while running with npx. I will look into it this week.
