Heroku push failing with build errors

Question

I have a node.js / reactjs / js applciation that I am trying to push to Heroku. I pushed using the proper commands

git add .
git commit -m "message"
git push Heroku master

once I do that, it takes about 2 minutes, and shows all this stuff below:

I already uninstalled and reinstalled npm, as well as deleted package-lock.json, and node modules folder, then reinstalled with npm. any ideas?

Answer 1

That error log shows that you are successfully installing grpc version 1.24.6, and failing to install grpc version 1.20.0. The problem is that grpc version 1.20.0 is not compatible with the version of Node that you are using. You will need to either use an older version of Node, or upgrade that dependency to a newer version of grpc.
