npm install error with node <8.13

[Jony-Y]

Issue with firebase install while working with node lower than 8.13

firebase-tools: 7.8.0
env: MacOs

Steps to reproduce:

1. install firebase-tools 7.8.0
2. set node version to 8.12
3. run npm install / yarn

expected: modules installed successfully
actual:

The root cause is firebase-tools > @google-cloud/pubsub > @google-gax > “@grpc/grpc-js” “0.6.9"

there were no breaking changes done, nor did I upgrade firebase-tools lately.

This issue does not seem to follow the issue template. Make sure you provide all the required information.

@Jony-Y thanks for telling us about this! So as you said we now depend on @google-cloud/pubsub which has an engines requirement of 8.10.0 and that depends on @grpc/grpc-js which has an engines requirement of 8.13.0.

When using npm this actually isn't an issue. It will install the dependencies just fine and warn you about the difference. When using yarn however it looks like the engines-strict flag is set to true.

So here are a few options for workarounds:

• Use a later 8.x node version. I would recommend 8.15.0 since that is the version that Cloud Functions uses in the Node 8 runtime.
• Use yarn with the ---ignore-engines flag to install
• Install the Firebase CLI as a stand-alone binary following the instructions on this page: https://firebase.google.com/docs/cli#install_the_firebase_cli
