I can't install Pyright

[HHKSYT]

I used the commend :CocInstall coc-pyright,and I got the error saying

errno FETCH_ERROR

Network issue, your network is not stable and can't connect to NPM servers properly, the downloaded resources is not complete.

Try npm cache clean --force to clean npm cache, and try again.
