What does this Error Code 1 mean? /@npmcli/promise-spawn/index.js:64:27

It looks like Node fails to spawn worker threads, but that's just a guess.

Is there anything I can do to get a better error message?
Error code 1 does not help me.

Is it related to this closed but unresolved thread?
npm/npm#3139

@AlphaJuliettOmega thanks for stopping by.

This feedback discussions repo is for discussing new features for npm, not for technical support. It seems like your best bet would be to open an issue over on the react-native repo to get support.
