React-native: (react-native run-android --variant=release) Error: spawnSync ./gradlew ENOBUFS

Created on 2 Dec 2019 · 17Comments · Source: facebook/react-native

This issue has popped up when I try to run my android app with any of my release-based variants. The app runs properly when not specifying a variant (using the debug variant), and I am also able to successfully create release .apk/.aab files as well.

When running npx react-native run-android --variant=release, the process goes on as normal until it reaches this point:

after which it will consistently log a giant set of warnings related to the index.android.bundle. Here is an excerpt:

We are also experiencing this issue.

Hermes Enabled

We are able to gradlew bundleRelease to build an apk/aab.

Happy to provide any additional details.

Update:
Rather than being tied to variant explicitly, it seems to occur anytime I'm both bundling AND disabling dev mode. For instance, this config in app/build.gradle for the debug variant will also fail:

project.ext.react = [
    bundleInDebug: true,
    devDisabledInDebug: true,
    entryFile: "index.js",
    enableHermes: true,
]

Croge32 on 2 Dec 2019

hey @Croge32 did you find any solution?

tal987 on 12 Dec 2019

I have the same issue and forced to use Android Studio to run a release app

booker-dragon on 6 Jan 2020

+1 I just discovered this issue and I don't know what to do. Nothing online too

paschaldev on 6 Jan 2020

got this issue when using wsl.

ItoshikiNozomu on 14 Jan 2020

Here, there is a workaround.
The error seems to be when enabling Hermes. Go to android/app/build.gradle and replace

project.ext.react = [
    entryFile: "index.js",
    enableHermes: true,  // clean and rebuild if changing
]

project.ext.react = [
    entryFile: "index.js",
    enableHermes: false,  // clean and rebuild if changing
]

This will allow you to compile the app.

fstovarr on 21 Jan 2020

Hi! Do you have any solution with enableHermes: true?

AlekseyKutsko on 22 Jan 2020

I need to compile the app when enableHermes: true
Nothing seems to work for now, any solutions?

farukyazici on 27 Jan 2020

Seeing this now as well... Any update @Croge32 ?

franzwarning on 6 Feb 2020

for me after enabling hermes and running

react-native run-android --variant release
