Cannot install @angular/cli@9.1.8 after install nodejs

Question

I've tried to install @angular/cli@9.1.8 (npm install -g @angular/cli)

Then the following error message appeared:

npm ERR! Response timeout while trying to fetch http://registry.npmjs.org/@angular-devkit%2fschematics (over 30000ms)

npm ERR! A complete log of this run can be found in: npm ERR!
C:\NODEJS\npm-cache_logs\2020-06-16T12_37_01_005Z-debug.log

These solutions I've tried but not work:

uninstall nodejs, delete all nodejs files related it and trying install nodejs versions(8,10,12).
uninstall angular(npm uninstall -g @angular/cli)
npm install --save-dev @angular-devkit/build-angular
npm cache clean --force
npm install -g @angular/cli --timeout=60000
npm config set registry http://registry.npmjs.org/

Tip:the problem appeared when I tried update angular 8 to angular 9.
