yarn start command failed with exit code 127

Question

Every time I try to start my project as usual using "yarn start" I get the "Command failed with exit code 127" error. I've realised I started to get this error once I've updated my iOS to Monterey v12.6.1 . My node version is not compatible with the yarn it seems like.

What have I tried to fix this:

• I have tried to upgrade/update my node version.
• I have uninstalled manually node/npm and yarn and reinstall them back with node version 16.0.0
• I have deleted the node_modules and package_lock.json
• I have had run the command "yarn" and every other update/upgrade command

Everything that I have tried failed.

This is the yarn error log:

Any other idea how to sort this out would be much appreciated.

Thank you for your time!

I’ve found the solution:

Use nvm to switch npm’s version to the newest ( 19.0.0 at that time ) and run “ yarn install “. This solved the issue!
