brew Error: No available formula with the name "node@11"

Question

I'm getting some errors with node v12.6 so I'm trying to downgrade to node@11.

Doing a brew install node@11 gives me the title error, and I've not found many results in Google for how to proceed.

Full error:-

brew search node gives me the following, so it doesn't appear I have 11 installed already.

leafnode          libbitcoin-node   llnode            node ✔            node-build        node@10           node@8            node_exporter     nodebrew          nodeenv           nodenv

Answer 1

I'm not sure what caused my error, but a way around this was to install v11 with NVM, following the guide below:-

https://www.npmjs.com/package/nvm

To install NVM, and then node version 11, just do the following:

$ brew install nvm
$ nvm install 11
