react-native: main.jsbundle does not exist. This must be a bug with

In my case, when compiling the bundle in release mode it was throwing a JS error, regarding using numbers like 15_000 instead of 15000. I had to look in the xcode logs above the actual error to see the problem, for some reason the process did not return 1 🤷

This fixed it for me: https://github.com/facebook/react-native/issues/29351#issuecomment-657929014 https://github.com/facebook/react-native/issues/29351#issuecomment-657906376

cd ios && pod install after npm update react-native

For me, the bundle command executed by react-native-xcode.sh tried to use the wrong index file and the solution in this Stack Overflow answer worked.

Turned out there was a syntax error in my source code, fixing the syntax error fixed the missing bundle error when archiving in Xcode. Not sure why Xcode didn’t report the syntax error while bundling for Android in command-line did.

For people who may encounter the same issue, just try to check your node or react native command could be found by XCode. Sometimes, this might be an issue if you are using nvm or fnm, especially when you are switching node versions.

This was the case for me, I was using node v14.16.1 which worked fine, then switched to v15.14.0 where it started to fail in production release.

@stefanoeb Thanks, that was my case as well. I find crazy how it works fine during development, but only fails when I try to generate a build to production. I spent an entire day today trying to figure out what was wrong until I found your message 😡

Thanks again for helping!

@stefanoeb May I ask how can we see the failure reason in the log?

@xilin If you’re building with Xcode check this place out:

If you’re using the CLI (like react-native run-ios) the output will be on the terminal directly, although it will be messy

Thanks. We use fastlane gym running with Jenkins, which is a little different. Will try to find it in log next time.

I tried absolutely everything I could find here and anywhere else but nothing helps - always ending up with the same error:

I even checked the dir and indeed, there is NO main.jsbundle file in there. I updated vom 0.63.2 to 0.63.4, I tried pretty much everything 😢 … can anyone help?
