I am trying to upgrade my node via homebrew but ran into a problem because I think I tried to download through the website. I am very new to terminal. I\'ve tried to search
I had the same error:
Linking /usr/local/Cellar/node/11.10.0...
Error: Could not symlink include/node /usr/local/include is not writable.
Solution:
$ sudo mkdir /usr/local/include
$ sudo chown -R $(whoami) $(brew --prefix)/*
$ brew link node
Linking /usr/local/Cellar/node/11.10.0... 7 symlinks created
$ node -v => v11.10.0
$ npm -v => 6.7.0
