我正在尝试在我的服务器上安装 yeoman，但由于某种原因，我一直收到权限被拒绝的错误.
i am trying to install yeoman on my server but for some reason do i keep getting a permission denied error.
$npm install -g yo
/root/.node/bin/yo -> /root/.node/lib/node_modules/yo/cli.js
> [email protected] postinstall /root/.node/lib/node_modules/yo
> yodoctor
sh: 1: yodoctor: Permission denied
npm ERR! [email protected] postinstall: `yodoctor`
npm ERR! Exit status 127
npm ERR!
npm ERR! Failed at the [email protected] postinstall script.
npm ERR! This is most likely a problem with the yo package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR! yodoctor
npm ERR! You can get their info via:
npm ERR! npm owner ls yo

推荐答案
我觉得 Shantaru 是对的，你需要用 sudo 来做.
I think Shantaru is right, you need to do it with sudo.
试试这个
sudo npm uninstall -g yo
sudo npm cache clean
sudo npm install -g yo
我在几周前遇到了类似的问题，并且有效.
I have a similar problem weeks ago and that works.
如果这不起作用，请先执行此操作:
If that didn't work, do this before:
npm config set unsafe-perm true
