I ran into a similar issue when using yarn, a temporary workaround is to include the --ignore-engines flag when adding the emulator (yarn global add @google-cloud/functions-emulator --ignore-engines).

Same here for node v9.11.2 via nvm and firebase 4.1.0. This problem seems to prevent me from using firebase serve for functions or firebase functions:shell :(

That's really strange that such an important part of Functions development is depending on such old version of Node :( Apparently, the emulator can run even under node 10.4.1 that I do have installed, so why not just remove the constraint from package.json? Using --ignore-engines did help indeed, but it's rather cumbersome to remember use it every time when installing some package.

Any news on this? I'm using Node 8 and have to add --ignore-engines every time I do anything with yarn.

Not to take away someone else's credit but... I believe this to be fixed as of 098e253!

Until it have been released though, you can also do echo ignore-engines true >> .yarnrc if you've grown tired of --ignore-engines. ;)

That doesn't fix the install constraint. Thanks for the .yarnrc trick though.
