Question

您好，我尝试了以下操作：

yarn -v => 1.3.2

brew list yarn =>

/usr/local/Cellar/yarn/1.13.0/bin/yarn
/usr/local/Cellar/yarn/1.13.0/bin/yarnpkg
/usr/local/Cellar/yarn/1.13.0/libexec/bin/ (5 files)
/usr/local/Cellar/yarn/1.13.0/libexec/lib/ (2 files)
/usr/local/Cellar/yarn/1.13.0/libexec/package.json

brew switch yarn 1.13.0 =>

Cleaning /usr/local/Cellar/yarn/0.24.6
Cleaning /usr/local/Cellar/yarn/1.7.0
Cleaning /usr/local/Cellar/yarn/1.13.0
Cleaning /usr/local/Cellar/yarn/1.12.3
2 links created for /usr/local/Cellar/yarn/1.13.0

但是yarn -v仍然=> 1.3.2

它也不在npm上 npm list -g --depth=0 =>

您可能想检查实际，而不是使用yarn命令在外壳程序上执行的which命令

$ which yarn
/usr/local/bin/yarn
$ ls -l /usr/local/bin/yarn
lrwxr-xr-x  1 hanxue  admin  30 Jan 17 01:59 /usr/local/bin/yarn -> ../Cellar/yarn/1.13.0/bin/yarn

您可能正在执行nvm安装的yarn的其他版本。我不建议同时使用nvm和brew。两者都是在多个版本的节点之间安装和切换的绝佳选择，但同时使用它们可能会引起冲突和混乱。
