yodoctor:从终端安装yo时找不到命令

以下是我不断得到的错误。它似乎表明了一个"安装后"与yodoctor的问题。可悲的是,yodoctor是自耕农队提出的帮助解决这个问题的建议。我安装了其他node_modules(bower,grunt,typescript)。

这个错误通常是因为有人在某个时候使用了sudo并搞砸了他们的npm包目录权限。根据经验,永远不要使用sudo。

那你怎么解决呢?这里有几个故障排除点:

  1. 确保将npm更新为最新版本(npm install -g npm)。 npm 2.x有一些竞争条件会在安装之前尝试运行yodoctor
  2. 确保全局npm模块文件夹为chown/chmod to your user
  3. 确保npm module binaries is in your PATH
  4. 如果没有任何效果,那么你可以通过运行npm i -g yeoman-doctor && npm i -g yo来强制安装它 - 但这确实是最后的求助解决方案。

只需以下命令即可:

sudo npm install -g yo

如果没有,找到yo的位置,将其添加到路径中,如下所示:

export PATH="$PATH:<path where yo is installed>"
