react-native: CLI: unexpected token '?'

Update note js to 16 resolve this problem

Also seeing this exact issue when trying to archive app in xcode after upgrading RN from 0.69.4 to 0.70.1

Node 16 is installed via nvm. Everything worked perfectly until now.

EDIT: Solved by

1. manually removing an old version of node (in /usr/local/bin/) that was apparently used by the sh shell (default shell used by xcode)
2. linking the nvm node installation by running ln -s $(which node) /usr/local/bin/node in a sh shell

I had the exact same issue. Running npx react-native run-android worked fine. Opening the upgraded project in Android Studio on my Ubuntu 22.04 machine resulted in the mentioned error.

In my case, I figured out, that i had two versions of node installed:

• System-wide Node 12 (!!) via package manager (/usr/bin/node)
• Locally NVM managed Node 17.2.0 (~/.nvm/versions/node/v17.2.0/bin/node)

Gradle seemed to use the system-wide Node 12 from /usr/bin/node, because it doesn’t pick up the NVM Paths. So i removed it from the system via apt remove nodejs.

As expected, opening the project again in Android Studio now resulted in an error, because node was not found: Caused by: java.io.IOException: Cannot run program "node" (in directory "/home/chris/documents/my-app/android"): error=2, File or directory not found

Finally I manually linked the “system node binary” to my NVM installed version: ln -s $(which node) /usr/bin/node

Now my project is building fine. Maybe that helps.

Update to NodeJS 16 is the solution for SyntaxError: Unexpected token '?' and not i am able to build the App using XCode.

I also ran into this! The issue at least in my case was the node export was pointing to the default installed version on the Mac, NOT the nvm managed version. On iOS this can be seen by a log Node found at: ${NODE_BINARY}. This was due to not having a .xcode.env file (whoops RN updating and missed this) and not having my NVM_DIR set in my bash path settings (since Xcode uses bash instead of zsh), which I did via these instructions. This might not be the exact issue observed here, but maybe it helps somebody!

I am getting this Error in Xcode while building & Archive.

Try and it may work(node v18.19.1):

1. remove node_module, yarn install
2. ./gradlew --stop
3. ./gradlew clean & ./gradlew assembleRelease

this solved it for me, thank you
