[0.60.2] Build failing when enabling Hermes (enableHermes: true) #25599

bhaskarGyan · 2019-07-11T17:54:36Z

Build is failing when I enable Hermes in android/app/build.gradle

clangen-nw · 2019-07-11T18:06:41Z

This seems to be caused by the hard-coded path to the hermes binary, here: https://github.com/facebook/react-native/blob/0.60-stable/react.gradle#L19

My npm install ended up placing it in a different location in node_modules, so I did the following in my android/app/build.gradle:

project.ext.react = [
    ...
    hermesCommand: "../../node_modules/hermesvm/%OS-BIN%/hermes",
    ...
]

@bhaskarGyan this issue has been fixed in #25598

burhanyilmaz · 2019-07-11T19:16:37Z

I have the same error :/ @bhaskarGyan did you solve it?

ecreeth · 2019-07-11T19:23:11Z

cc @bhaskarGyan @burhanyilmaz to fix this issue use the 0.60.3 React Native version

Karniej · 2019-07-11T19:27:29Z

@ecreeth I actually just installed 0.60.3 and my build succeeded , but the app crashes on start

burhanyilmaz · 2019-07-11T19:28:54Z

@ecreeth Thanks I solved this via #25598
it is really fast :)

ecreeth · 2019-07-11T19:33:58Z

@Karniej The React Native Team, recommend making sure everything works before trying to switch to Hermes. If everything is fine with your application, but with Hermes your application is broken, please send a issue

farshidshahmoradi1996 · 2019-07-11T19:41:23Z

I have same issue with 0.60.3 in --variant release
(in dev is ok )

What went wrong:
Execution failed for task ':app:bundleReleaseJsAndAssets'.

A problem occurred starting process 'command '....\node_modules\hermesvm\win64-bin\hermes''

ecreeth · 2019-07-11T19:49:39Z

@farshidshahmoradi1996 I'm not sure, but I think that before using the command, we must take a few steps before. Here

farshidshahmoradi1996 · 2019-07-11T20:05:22Z

when I open hermes.exe from node_modules\hermesvm\win64-bin that take error :

OS :win 8.1 (x64)

that problem comes from my windows?
I have this problem only in release version

bhaskarGyan · 2019-07-12T02:48:34Z

@ecreeth, #25598 fix the build issue but now the App is crashing on Startup.
Raised new issue #25601

I can close this issue if build is working for @farshidshahmoradi1996

farshidshahmoradi1996 · 2019-07-12T03:54:43Z

@bhaskarGyan build is not working in --variant release

burhanyilmaz · 2019-07-12T04:31:30Z

There is no problem production and development in my app. But not starting js server when running react-native run-android.
There is a solution that react-native start & react-native run-android. it is not good.
Hermes cause this problem? @ecreeth

cpojer · 2019-07-12T10:37:30Z

Fixed in 0.60.3.

zenz · 2019-07-12T12:44:22Z

Fixed in 0.60.3.

Not fixed under windows indeed.

zenz · 2019-07-12T13:29:55Z

As @farshidshahmoradi1996 said that, while run
node_modules\hermesvm\win64-bin\hermes.exe
individually. it told me it's lack of some dlls.

So I search and download this icu4c-64_2-Win64-MSVC2017.zip, unzip it and put relative dll to \windows folder, then run hermes.exe again, there's no error showing again.
But when run
react-native run-android --variant=release
still failed with same error:

* What went wrong:
Execution failed for task ':app:bundleReleaseJsAndAssets'.
> A problem occurred starting process 'command '..\..\node_modules\hermesvm\win64-bin\hermes''

zenz · 2019-07-12T14:26:30Z

investigated some time on it, I found that running hermes.exe need those dlls

api-ms-win-crt-convert-l1-1-0.dll
api-ms-win-crt-environment-l1-1-0.dll
api-ms-win-crt-heap-l1-1-0.dll
api-ms-win-crt-locale-l1-1-0.dll
api-ms-win-crt-math-l1-1-0.dll
api-ms-win-crt-runtime-l1-1-0.dll
api-ms-win-crt-stdio-l1-1-0.dll
api-ms-win-crt-string-l1-1-0.dll
api-ms-win-crt-time-l1-1-0.dll
api-ms-win-crt-utility-l1-1-0.dll
icudt64.dll
icuin64.dll
icuuc64.dll

and with those dlls in \Windows dir, I can run
echo "'use strict'; function hello() { print('Hello World'); } hello();" | ./hermes
in Git-Bash and get "Hello World". But still when try to compile the apk, it failed.
Should be close to the solution.

zenz · 2019-07-12T14:39:29Z

use hermes to compile the bundle file, I can get new bundle file, but with those error logs.

Is this means the hermes is not a complete engine for windows?

zenz · 2019-07-14T09:32:30Z

modify react.gradle file to add cmd /c before execute hermes can solve the error message. but no matter how, hermes cannot translate some elements as my previous comment is the problem. this makes the return result not zero. then the process stop there.

chuanhaisoft · 2019-07-15T03:42:28Z

0.60.3 same problem:

Any news about this problem?

willholen · 2019-07-15T20:52:03Z

Hermes requires the Microsoft Visual C++ 2015 Redistributable, and the ICU4C libraries which were accidentally omitted in the first NPM release (but can be found on the GitHub release).

There are undoubtedly several issues at work in this thread though. We're aiming to publish a new NPM this week to address several of them.

MakhouT · 2019-09-18T14:41:39Z

Well I also have issues with Hermes
I've enabled it like this

dependencies {
    implementation project(':react-native-webview')
    implementation project(':react-native-fs')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.facebook.react:react-native:+"  // From node_modules
    implementation project(':react-native-navigation')

    if (enableHermes) {
        def hermesPath = "../../node_modules/hermesvm/android/";
        debugImplementation files(hermesPath + "hermes-debug.aar")
        releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

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

In my react native component I am having this

  const usingHermes = typeof HermesInternal === 'object' && HermesInternal !== null;
  console.log(typeof HermesInternal); // undefined

{!usingHermes ? (<Text style={styles.footer}>Engine: None</Text>) : (
            <View style={styles.engine}>
              <Text style={styles.footer}>Engine: Hermes</Text>
            </View>
          )}

It always outputs None on my component. Am I missing something?
And yes I cleaned my android build folder with ./gradlew clean

Jeet007das · 2019-09-18T15:03:38Z

@ErHarinderSingh
First add hermes-engine
yarn add --dev [email protected]
Then try to enable hermes in android/app/build.gradle with
project.ext.react = [
    entryFile: "index.js",
    enableHermes: true,  // clean and rebuild if changing
    hermesCommand: "../../node_modules/hermes-engine/%OS-BIN%/hermes",
]
and then replace node_module/react-native/react.gradle with this file:
workable react.gradle file
I think this time you can make it to run with command
react-native run-android --variant release
or use
./gradlew assembleRelease to build your app on Windows.
it worked for me on Linux

Thank you soo its working to following these steps. thanks a lot

zenz · 2019-09-25T15:36:06Z

I'm really disapointed.
Today the RN 0.61.1 was released. but this patch still not there! We the programers who use Windows still need to apply the patch by ourselves. What a joke!

Today the RN 0.61.1 was released. but this patch still not there! We the programers who use Windows still need to apply the patch by ourselves. What a joke!

You are right bro. I am shocking why they have not added new working react.gradle file there with hermes release. We still have to change react.gradle file. If we have to add any package like gmaps etc; then react.gradle file changes again and we have to again modify it.

Yeah! I was hoping to find a way to prevent react.gradle from being overwritten every time I install a package. It's quite annoying. I don't believe they're not aware of this problem on Windows.

use hermes to compile the bundle file, I can get new bundle file, but with those error logs.

Is this means the hermes is not a complete engine for windows?

The error still occurs on Windows even after upgrading to 0.61.1.

The PR fix was merged two days ago: #26556. Hopefully, we will see it in the next update.

I am using 0.61.2, still I am getting same error of hermes in window...

It works in ubuntu and not working in window. If I need to reduce the size of apk using hermes, then I need to used ubuntu for that

usmansbk · 2019-10-08T21:01:35Z

@willholen
Is this a super bug?
Is something wrong with the patch we've been using?
Should Windows users migrate to a different OS?
Why won't they fix this bug? Modifying the react.gradle file is really annoying.

Maskedman99 · 2019-10-25T20:01:36Z

Running ./gradlew bundleRelease is giving many similar kind of errors with different variables

Eventhough an app.abb is being created app crashes while running.
However react-native run-android --variant=release works fine.
I am using Linux ( Ubuntu ) and facing the problem :(

riazXrazor · 2019-10-29T07:32:50Z

i am using 0.60.5 still facing the issue :(
@andreasbergqvist fix worked

mikehardy · 2019-10-29T20:54:33Z

Yeah, it was merged to master but that was after the 0.61-branch was cut, so it hasn't made it in a release there. I just added the commit to the request for cherry-picks on 0.61 after seeing @LuigiMaestrelli mention it.

I just checked on 0.62-stable and it's on there https://github.com/facebook/react-native/blob/0.62-stable/react.gradle#L153 so whenever 0.62.0 comes out (it's really close but is blocked on CI failures if anyone wants to lend a hand...) it will have it as well.

Until then get yourself some patch-package goodness - makes incorporating known fixes in old releases super easy and reliable across all installs of your project :-). Cheers
