重新安装node.js后npm问题

Question

我最近在我的计算机(运行Windows 10)上重新安装了node.js(最新版本,9.8.0),因为它开始出现故障.

问题是,现在npm不起作用.例如,在输入npmcmd时,我收到错误:

Error: EPERM: operation not permitted, mkdir 'C:\Program Files (x86)\Nodist'

但是,node命令工作正常.为什么会这样？

编辑:我已经尝试恢复到推荐的Node.js版本(8.10.0),但我遇到了同样的问题.

我刚才有类似的问题.尝试导航到名为.npmrc,in 的文件C:\Users\%UserName%并将其删除.
