先使用 brew 卸载 node
➜ ~ brew -v
Homebrew 2.0.3
Homebrew/homebrew-core (git revision b295f; last commit 2019-03-09)
执行 brew uninstall node
如果出现拒绝卸载，例如如下情况
➜ ~ brew uninstall node
Error: Refusing to uninstall /usr/local/Cellar/node/11.1.0
because it is required by yarn, which is currently installed.
You can override this and force removal with:
brew uninstall --ignore-dependencies node
忽略依赖卸载 node brew uninstall --ignore-dependencies node
➜ ~ brew uninstall --ignore-dependencies node
Uninstalling /usr/local/Cellar/node/11.1.0... (3,936 files, 47.0MB)
node 10.8.0 is still installed.
Remove all versions with `brew uninstall --force node`.
➜ ~ node -v
v13.6.0
执行 brew uninstall --force node 卸载所有版本
➜ ~ brew uninstall --force node
Uninstalling node... (4,022 files, 48.7MB)
➜ ~ node -v

➜ ~ brew uninstall node
Error: No such keg: /usr/local/Cellar/node
➜ ~ node -v

3.检查 ~/local 目录下的 node, node_modules 相关文件夹, user 为本机用户名
➜ ~ find ~/local -name node
/Users/user/local/bin/node

/Users/user/local/share/doc/node
➜ ~ find ~/local -name node_modules
/Users/user/local/lib/node_modules
rm -rf /Users/user/local/bin/node /Users/user/local/include/node /Users/user/local/share/doc/node /Users/user/local/lib/node_modules
➜ ~ rm -rf /Users/user/local/bin/node /Users/user/local/include/node /Users/user/local/share/doc/node /Users/user/local/lib/node_modules`
