npm安装任何依赖包都无效，但是npm和node确实都是OK的。换了国内的淘宝镜像也无效。

上传不了图片，贴下代码。

今天5月18日重新安装了node和npm，通过pkg安装包安装的，依然报错。真是日了狗了

Answer 1

第一步给目录加权限：
sudo chmod -R 777 /var/root
第二步安装包
npm install koa  -g --unsafe-perm

并不是npm或者node本身的问题。需要root目录的权限。

Answer 3

换一个node版本

Answer 4

npm坏了，需要重装node

Answer 5

刚刚遇到这个问题也来说一下吧。如果你使用了n包来管理node版本，切换的时候务必要加上sudo，即 sudo n,否则虽然node -v 显示正常，但是install命令就会用不了
