yodoctor:从终端安装 yo 时找不到命令

yodoctor: command not found when installing yo from terminal

以下是我不断收到的错误。这似乎表明 yodoctor 存在 "post-install" 问题。遗憾的是,yodoctor 是 yeoman 团队提供的帮助解决这个问题的建议。我安装了其他 node_modules(bower、grunt、打字稿)。

sh: yodoctor: command not found

这个错误一般是因为有人在某个时候使用了sudo,弄乱了他们的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 模块文件夹是 chown/chmod to your user
  3. 确保npm module binaries is in your PATH
  4. 如果没有任何效果,那么您可以通过 运行ning npm i -g yeoman-doctor && npm i -g yo 强制安装它 - 但这确实是最后的解决方案。

只需以下命令即可解决问题:

sudo npm install -g yo

如果没有,找到yo在哪里,添加到路径如下:

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