Bundling Android async function run() error

[mikeKane]

Environment

react-native-cli: 2.0.1
react-native: 0.59.4

Description

I am attempting to bundle the android project using this

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

However I am getting this error

node_modules/@react-native-community/cli/build/cliEntry.js:168
async function run() {
      ^^^^^^^^

Which version of Node do you use? Can you run react-native info?

[mikeKane]

Sure.

We'll definitely need a repo which we can download and investigate. Please provide one

[mikeKane]

I'm not sure I am able to give access to this repo. Here is the output from Android Studio. Does this help?

Is there a possibility that your Android Studio uses different Node version, i.e. below 8.3?

[mikeKane]

I don't think but Im not very experienced with Android Studio. Do you know where I would check that? If I build debug it works fine. Release builds throw up this error

[mikeKane]

I do see

android {
    compileSdkVersion rootProject.ext.compileSdkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

in the App/build.gradle

[mikeKane]

`node -v
v6.4.0

If this helps also

[thymikee]

React Native (and this CLI as well) doesn't support Node 6. You need to use Node 8.3+. Please upgrade and the error will be gone :)

[mikeKane]

android _kane7161$ node -v
v10.15.3
I still see the issue

I've updated all of my modules also

[thymikee]

Interesting fact: when you ran react-native info to provide us with details of your package, it also used the cliEntry.js file where you have your error reported. Please fix your environment, I have no ways to do so unfortunately.

Also make sure you're running the latest version of @react-native-community/cli, which is 1.9.2 (remove it from lockfile and install react-native again)

[mikeKane]

@thymikee Can you explain a bit more about the first issue you described? Im not sure I follow what you mean

[thymikee]

I'm talking about this message: #342 (comment).

The error comes from node_modules/@react-native-community/cli/build/cliEntry.js:168 which is used when running any command, e.g. react-native info. So I just say it's weird you get a syntax error when running one command, but not the other.

If you can't share the project, you can create a sample one and show me the error. Or record a video that shows what actions do you perform that result in this problem.
