npm - 优医生 : command not found when installing yo from terminal

Question

下面是我不断收到的错误。这似乎表明 yodoctor 存在“安装后”问题。遗憾的是 yodoctor 是 yeoman 团队提供的建议来帮助解决这个问题。我安装了其他node_modules(bower、grunt、typescript)。

sh: yodoctor: command not found

此错误通常是因为有人在某些时候使用了 sudo 并弄乱了他们的 npm 包目录权限而引起的。根据经验，永远不要使用 sudo。

那么如何解决这个问题呢？以下是一些故障排除要点:

1. 确保将 npm 更新到最新版本 (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. 如果不起作用，那么您可以通过运行npm i -g yeoman-doctor && npm i -g yo来强制安装它 - 但这确实是最后的解决方案。
