npm 安装总是停留在那个确切的时间

Question

I tried running $ npm install -g truffle and $npm install but it was constantly freezing at a particular point.

I also tried command yarn global add truffle but it was generating an error.

I looked for answers on the inte.net one of which suggested to run npm config set registry http://registry.npmjs.org/ and then npm install , but now I'm receiving the error:

EPERM: operation not permitted, unlink 'C:\Users\dell\AppData\Roaming\npm\node_modules\.staging'
yarn command now freezes after a point

I'm a beginner, please help.

It happens to me many times when I'm using Windows. What I did to make it continue after I felt that it was froze is

1. Click the terminal. Make sure you set the focus on the terminal

2. Hit ctrl + k
