Homebrew-在OSX上设置特定版本的节点

Question

我正在尝试为我的新项目设置节点v 8的要求（因为我想使用react-redux-firebase生成器，它需要v8）。

我在遵循SO和Homebrew上的说明时遇到了麻烦-它们似乎已过时。

我目前正在运行node -v并获得v 10.13.0。

Brew Unlink节点返回

Error: No such keg: /usr/local/Cellar/node

brew搜索节点返回：

酿造链接--overwrite --force node @ 8

Linking /usr/local/Cellar/node@8/8.12.0... 
Error: Could not symlink lib/node_modules/npm/.mailmap
/usr/local/lib/node_modules/npm is not writable.

我不能在此命令上使用sudo，因为Homebrew不再支持它。

有谁知道如何让节点v 8运行？

我尝试的所有操作均返回结果，指出当前版本为10
