How Do I Uninstall Yarn
Depends on how you installed it:
brew: brew uninstall yarn
tarball: rm -rf "$HOME/.yarn"
npm: npm uninstall -g yarn
ubuntu: sudo apt-get remove yarn && sudo apt-get purge yarn
centos: yum remove yarn
windows: choco uninstall yarn
(or go to control panel > add/remove programs and uninstall it from there)
Try this, it works well on macOS:
$ brew uninstall --force yarn$ npm uninstall -g yarn$ yarn -v
v0.24.5 (or your current version)
$ which yarn
/usr/local/bin/yarn
$ rm -rf /usr/local/bin/yarn$ rm -rf /usr/local/bin/yarnpkg$ which yarn
yarn not found
$ brew install yarn $ brew link yarn$ yarn -v
v1.17.3 (latest version)
