also when i try to run firebase serve --only functions it gives following error and runs only hosting functions: Cannot start emulator. Error: Cannot find module '@google-cloud/functions-emulator/src/config'

Have similar issue with install of cloud functions. Version of node: v8.9.4

[mixcas]

Same here. I can't install @google-cloud/functions-emulator and can't run firebase serve --only functions.

This is my output:

Using node: 8.9.4 npm: 5.6.0

Also if i try to install using sudo yarn global add @google-cloud/functions-emulator it doesn't return any errors but running function prints a lot of source code from zsh.

Maybe this should help :

cd /usr/local/lib/ sudo npm install @google-cloud/functions-emulator sudo npm install -g @google-cloud/functions-emulator

[dsouzaedison]

I am not sure what exactly is causing this problem. But here is the working solution. StackOverflow - Firebase: Cannot start emulator

[stephenmathieson]

Any updates here?

It's very discouraging that this issue has been open for over a year without a maintainer acknowledging it.

The yarn solution worked for me: https://stackoverflow.com/a/52877585/3180309
