Problem in Creating an angular project with NodeJS

Question

I'm trying to create a project after installing angular-cli in my system. When I give ng new project-name command I'm getting an error as follows.

ERROR:

 21328 verbose stack Error: EPERM: operation not permitted, unlink 'C:\\Windows\\System32\\sampleproject\\node_modules\\.staging\\typescript-d81c34c0\\lib\\typescript.js' 21329 verbose cwd C:\\Windows\\System32\\sampleproject 21330 verbose Windows_NT 10.0.17134 21331 verbose argv "C:\\\\Program Files\\\\nodejs\\\\node.exe" "C:\\\\Program Files\\\\nodejs\\\\node_modules\\\\npm\\\\bin\\\\npm-cli.js" "install" "--quiet" 21332 verbose node v12.6.0 21333 verbose npm v6.9.0 21334 error path C:\\Windows\\System32\\sampleproject\\node_modules\\.staging\\typescript-d81c34c0\\lib\\typescript.js 21335 error code EPERM 21336 error errno -4048 21337 error syscall unlink 21338 error Error: EPERM: operation not permitted, unlink 'C:\\Windows\\System32\\sampleproject\\node_modules\\.staging\\typescript-d81c34c0\\lib\\typescript.js' 21338 error [OperationalError: EPERM: operation not permitted, unlink 'C:\\Windows\\System32\\sampleproject\\node_modules\\.staging\\typescript-d81c34c0\\lib\\typescript.js'] { 21338 error cause: [Error: EPERM: operation not permitted, unlink 'C:\\Windows\\System32\\sampleproject\\node_modules\\.staging\\typescript-d81c34c0\\lib\\typescript.js'] { 21338 error errno: -4048, 21338 error code: 'EPERM', 21338 error syscall: 'unlink', 21338 error path: 'C:\\\\Windows\\\\System32\\\\sampleproject\\\\node_modules\\\\.staging\\\\typescript-d81c34c0\\\\lib\\\\typescript.js' 21338 error }, 21338 error stack: "Error: EPERM: operation not permitted, unlink 'C:\\\\Windows\\\\System32\\\\sampleproject\\\\node_modules\\\\.staging\\\\typescript-d81c34c0\\\\lib\\\\typescript.js'", 21338 error errno: -4048, 21338 error code: 'EPERM', 21338 error syscall: 'unlink', 21338 error path: 'C:\\\\Windows\\\\System32\\\\sampleproject\\\\node_modules\\\\.staging\\\\typescript-d81c34c0\\\\lib\\\\typescript.js', 21338 error parent: 'sampleproject' 21338 error } 21339 error The operation was rejected by your operating system. 21339 error It's possible that the file was already in use (by a text editor or antivirus), 21339 error or that you lack permissions to access it. 21339 error 21339 error If you believe this might be a permissions issue, please double-check the 21339 error permissions of the file and its containing directories, or try running 21339 error the command again as root/Administrator (though this is not recommended). 21340 verbose exit [ -4048, true ]

What is the problem with this and how to resolve this?

Can some one help me out with this?

Answer 1

It seems is a Windows permissions problem, firstly try to do the following:

npm cache clean

If that doesn't fix the problem, look at %APPDATA%\\npm-cache to clean this directory, or in PowerShell you can run, $env:APPDATA\\npm-cache .

After cleaning the cache, you may still be left with remnants. Manually remove everything in that directory, and try again.
