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
