Firebase-tools: npm install -g firebase-tools fails but npm install -g [email protected] works

[lc-chrisbarton]

A few hours ago running npm install -g firebase-tools in our CI system started failing. We pinned to v7.7.0 to fix the issue.

Does not work

npm install -g firebase-tools

Works

npm install -g [email protected] works

I have... news. First, I can replicate this. Yaaaayyyy.....

Second, I can put my finger on the fact that we now include @google-cloud/pubsub as a dependency for the emulators, which includes protobufjs. protobufjs was previously only a dev dependency, so it never would have run it's postinstall script in the container like this.

When running postinstall scripts, npm attempts to not run as root (for reasons). When running as root, npm will try to prevent the user from doing things that could have bad consequences. There is a parameter named unsafe-perm that can disable this.

Either run the npm install -g in the container as root with the --unsafe-perm flag (preferred, generally), or do npm config set unsafe-perm true somewhere before (which turns off this behavior everywhere, which wouldn't be desirable outside of a container, probably).

I hope that answers your question!

Thanks that worked npm install --unsafe-perm -g firebase-tools

[yakubu234]

in my case this worked for me
npm install --unsafe-perm -g firebase-tools
then followed by
npm install --unsafe-perm -g firebase
and lastly
npm i firebase

bkendall, you rock! Your solution worked for me at once. Thanks for providing the explanation as well!
