回答1:

The files in /usr/local/lib/node_modules/firebase-tools/node_modules are not being updated and installed as expected. Many of the modules are missing.

I had installed firebase locally into what I am going to use as my firebase directory. All of the modules where there. So I copied the files from the local node_modules folder to the global node_modules folder.

To note, this is a bandage to the problem as anytime you go to update firebase you will need to repeat this process.
