Angular-CLI ng new: “Error: EPERM: operation not permitted…”

Question

I am trying to use Angular-CLI to install a new Angular2 app, but keep running into the following issue:

ng new payment-calc-app

After \"Install

Answer 1

• Use command: npm install -g @angular/cli --no-optional
• Close current angular project folder (in this case payment-calc-app)
• Give parent folder read & write permission & archive permission (right click parent folder & give permissions to folder & child
  folders)
  • Open NodeJs command prompt in administrator mode
  • Run command ng new payment-calc-app

Answer 2

I had the same problem and the solution that worked for me is running the IntelliJ as an administrator

Answer 3

In my case the problem was that I had another command prompt with 'ng serve' running, I stopped the process and the creation completed successfully

Answer 4

if you are getting this type of error when you are trying an ng build --prod

close VS Code and in file explorer go to the dist folder (same level as the src folder)... manually delete this

then try again

Answer 5

I had this same issue. I solved it by rolling back to NodeJS LTS. For me, 11.7 Current was the issue. I combed the inter webs and discovered that Current doesn't get tested with NPM all the time, so in a way, Current is how that team tests NodeJS in the wild. Best of luck to anyone having this issue.

Answer 6

I know the OP specified they ran it as an Administrator, but for me that solved the issue. Simply running my build as an administrator worked.
