Hello everyone, I encountered an error when installing Hexo using Windows CMD. Git and Nodejs have been installed. What's the problem? The following is the error code:

C:\Users\py_vc>npm install -g hexo-cli
npm ERR! code EPERM
npm ERR! syscall mkdir

Who can give me the answer?Thank you.

@WrunDorry
Just as the error log said. Please check the permission of C:\Program Files\nodejs\node_cache\_cacache.

I assume you can solve this issue if you run a terminal with "Run as Administrator" or kill a process that opens the C:\Program Files\nodejs\node_cache\_cacache directory.

Thank you.
