Angular8 node js and npm installation problems

I'm learning angular js. For this I've install nodejs and git. And I've run following command on CMD:

  npm install -g @angular/cli@latest

After some time following error occurred

npm WARN rollback Rolling back @schematics/[email protected] failed (this is 
probably harmless): EPERM: operation not permitted, lstat 'C:\Users\User 
Name\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\@schematics'
npm ERR! code EEXIST

npm ERR! EEXIST: file already exists, cmd shim 'C:\Users\Chaitanya

npm ERR! File exists: C:\Users\User Name\AppData\Roaming\npm\ng.ps1
npm ERR! Remove the existing file and try again, or run npm

npm ERR!     C:\Users\User Name\AppData\Roaming\npm-cache\_logs\2020-01- 
04T12_12_30_922Z-debug.log

Can you please explain what is that error and how I could solve this. I am using Window 10.

Run this commands and manually delete the exist files if does not work.

Completely uninstall angular-cli from your machine

npm uninstall -g angular-cli

Clean npm cache

npm cache clean --force

Reinstall angular cli,

npm i @angular/cli@latest -g

Delete this file going to the location.

In the terminal navigate to the following path: C:\Users\UserName\AppData\Roaming\npm\node_modules and delete angular file and reinstall cli. That worked for me.

Also do check if you've set your path variables correctly.

You can try opening the Command Prompt with Administrator privileges and then run the command.
