yodoctor:从终端安装yo时找不到命令

jes*_*son 8 npm yeoman yeoman-generator yo

以下是我不断得到的错误.它似乎表明了yodoctor的"安装后"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sudo在某些时候使用并弄乱了他们的 npm 包目录权限而引起的。根据经验,永远不要使用 sudo。

那么如何解决它呢?以下是几个故障排除点:

  1. 确保将 npm 更新到最新版本 ( npm install -g npm)。yodoctornpm 2.x 有一些竞争条件,会在安装之前尝试运行。
  2. 确保全局 npm 模块文件夹是chown/chmod到您的用户
  3. 确保npm 模块二进制文件位于您的 PATH 中
  4. 如果没有任何效果,那么您可以通过运行强制安装它npm i -g yeoman-doctor && npm i -g yo- 但这确实是最后的解决方案。
