iOS main.jsbundle does not exists – Bundle React Native code and images

[carloscuesta]

Hello!

I have updated an app from react-native@0.55.4 to react-native@0.59.9 and I'm having problems with the iOS build step Bundle React Native code and images. The problem is that when the build gets on this step on the CI machine, fails automatically throwing the following error:

'error: File /Users/travis/Library/Developer/Xcode/DerivedData/app-arslyffdnfsjkgdxahmrdswzporu/Build/Intermediates.noindex/ArchiveIntermediates/app/BuildProductsPath/Release-iphoneos/appName.app/main.jsbundle does not exist. This must be a bug with React Native, please report it here: https://github.com/facebook/react-native/issues'

What bothers me is the thing that I can make a bundle on the CI machine using the react-native bundle command without any problems or issues So I can safely assume that there's no problem with the bundle creation.

From what I've read at #18472, I tried the proposed solutions such as ensuring that the version of node it's specified by nvm as default, tried to use another version of Xcode, tried to use a newer version of Node. Nothing fixed the problem. Also I've tried to debug the issue and seems that this command it's not being executed. The thing is that this script itself doesn't give any output of what happened on success or fail.

This is the error log:

React Native Environment

I'm running the builds on a Travis CI machine and before the bump to 0.59.9 this never happened.

1. Run the following command:

Describe what you expected to happen:

I expect that the main.jsbundle file is created successfully through the step of Bundle React Native code and images as it does if I do it manually using the react-native bundle command.

Thanks 🙏

After debugging out the issue, I found the problem, leaving it here just in case could help anyone:

On Xcode at the Bundle React Native code and images Build Phase I've set up the NODE_BINARY to the result of which node.

Then the CI finds always the correct binary regardless the node install method.

export NODE_BINARY=$(which node)

@carloscuesta that didn't work for me but removing the entire Bundle React Native code and images build phase did work

[carloscuesta]

But removing the whole step is not a solution since it’s required I guess for building the application.

It has a purpose, otherwise won’t be set at the build step

@carloscuesta

You are very right. I just didn't get the build error and thought it fixed it.

Any idea why your solution didn't work for me or anything you think I should test out?

[carloscuesta]

Maybe you have another problem that's not related with the bundling itself, can you bundle your application in your local machine with this step ?

Take a look at #18472 @CaptainJeff

I've got this problem upgrading react-native to 0.61.1. The build only fails when using Travis CI, compiling locally works perfectly. Did any of you find a solution?

[carloscuesta]

Yes, I was having the exact same problem as you @jaumevn this solved the issue: #25522 (comment)

[jaumevn]

Thanks, I've just tried it and works..!

@carloscuesta Do you still run react-native bundle to generate the main.jsbundle manually? Or just plainly using which node fix?
