yodoctor:从终端安装yo时找不到命令 [英] yodoctor: command not found when installing yo from terminal

问题描述

以下是我不断遇到的错误.似乎表明yodoctor存在安装后"问题.可悲的是yodoctor是yeoman团队提供的建议来帮助解决此问题.我还安装了其他node_modules(bower，grunt，打字稿).

Below is the error I keep getting. It seems to indicate a "post-install" issue with yodoctor. Sadly yodoctor is the advice given by the yeoman team to help with this issue. I have other node_modules installed (bower, grunt, typescript).

sh: yodoctor: command not found

推荐答案

此错误通常是由于某人有时使用sudo并弄乱了其npm软件包目录权限而引起的.根据经验，永远不要使用sudo.

This error is generally caused because someone used sudo at some point and messed up their npm package directory permissions. As a rule of thumb, never ever use sudo.

那么如何解决呢?以下是一些疑难解答要点:

So how can you fix it? Here's a couple troubleshooting points:

1. 确保将npm更新为最新版本(npm install -g npm). npm 2.x具有某些竞争条件，会在安装yodoctor之前尝试运行.
2. 确保全局npm模块文件夹为 chown/chmod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，则可以通过运行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法.

1. Make sure you update npm to the latest version (npm install -g npm). npm 2.x had some race conditions that would try to run yodoctor before it is installed.
2. Make sure the global npm module folders is chown/chmod to your user.
3. Make sure npm module binaries is in your PATH.
4. If nothing works, then you can force install it by running npm i -g yeoman-doctor && npm i -g yo - but that really is a last recourse solution.
