How can I fix command line error supportedNodeVersions when deploying Firebase cloud functions?

Question

I upgraded firebase tools and after I updated the tools I get this error when I use any of the firebase commands.

Ex. firebase login or firebase deploy --only functions

/.nvm/versions/node/v10.5.0/lib/node_modules/firebase-tools/node_modules/@grpc/grpc-js/build/src/index.js:47
throw new Error(`@grpc/grpc-js only works on Node ${supportedNodeVersions}`);
^

Error: @grpc/grpc-js only works on Node ^8.13.0 || >=10.10.0

I have upgraded node

node -v
v10.5.0

npm -v
6.14.4

Even after upgrading everything I still run into this error. How can I fix this or is there another way I can deploy my functions?

Check the following error message.

Error: @grpc/grpc-js only works on Node ^8.13.0 || >=10.10.0

The Node version that you are using at local machine is v10.5.0.

If you want to use Node 10 then you should use v10.10.0 or higher version(ex. v10.20.1).

nvm install v10.20.1
nvm alias default v10.20.1
npm install -g firebase-tools
