Why doesn't yarn updated when running upgrade?
There's a lengthy thread on Github regarding upgrades; here's what is suggested for HomeBrew:
brew upgrade yarn
brew link --overwrite yarn
Then try yarn -v
If that fails then you could:
First, uninstall brew's yarn:
brew uninstall yarn
Removing yarn binaries manually:
rm -f /usr/local/bin/yarnpkg
rm -f /usr/local/bin/yarn
Remove yarn cache:
rm -rf ${HOME}/.yarn
If you have the following in your .zshrc or .bash_profile, remove it:
export PATH="$PATH:`yarn global bin`"
Install via curl:
curl -o- -L https://yarnpkg.com/install.sh | bash
Make sure there is the following line in your .zshrc or .bash_profile:
export PATH="$HOME/.yarn/bin:$PATH"
