Hyperlink 安装纺纱机'；brew链接节点'；

当我试图通过自制设备安装纱线时。收到以下消息

My-MacBook-Pro:share gt$ brew install yarn
Error: You must `brew link node` before yarn can be installed
My-MacBook-Pro:share gt$ 

运行brew链接节点导致

My-MacBook-Pro:share gt$ brew link node
Linking /usr/local/Cellar/node/7.6.0... 
Error: Could not symlink bin/node
Target /usr/local/bin/node
already exists. You may want to remove it:
  rm '/usr/local/bin/node'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

To list all files that would be deleted:
  brew link --overwrite --dry-run node
My-MacBook-Pro:share gt$ 

所以我尝试了覆盖选项

My-MacBook-Pro:share gt$ brew link --overwrite node
Linking /usr/local/Cellar/node/7.6.0... 
Error: Could not symlink share/doc/node/gdbinit
/usr/local/share/doc/node is not writable.
My-MacBook-Pro:share gt$ 

对/usr/local/share执行chmod后，它会抱怨/usr/local/lib/dtrace不可写

我是走对了路还是只是一个兔子洞？什么是安装Thread的干净方法？

在macOS和通用Unix环境中安装Thread最简单的方法之一是通过我们的shell脚本。您可以通过在终端中运行以下代码来安装纱线：

curl -o- -L https://yarnpkg.com/install.sh | bash
