问题
So when trying to run the angular4 project today my first error was : npm install eperm operation not permitted so I thought to delete my node modules folder and retry. But running npm install I am running in to this error npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "start". I've closed vscode to try and run the install to make sure nothing was locking it. I've tried npm cache clean but results in errors.
Todays latest struggles :
0 info it worked if it ends with ok
1 verbose cli [ 'C:\\Program Files\\nodejs\\node.exe',
1 verbose cli 'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-
cli.js',

1 verbose cli '@angular/cli@latest' ]
2 info using npm@5.5.1
3 info using node@v8.9.3
4 verbose npm-session 2a0bb102467943cf

7 error cb() never called!

Any suggestions?

I had the same issue. After cache clean and updating npm everything is ok. So try to run:
npm cache clean --force
npm install -g npm@latest

There are 2 solutions for this
- you can run "npm cache clean"
- you run the command prompt in admin mode.

Install by yourself the module that is giving the error.
After spending many hours and trying all the possible suggestions, I found that installing the specific module mentioned by the error globally fixed the issue:
For Example: npm ERR! { Error: EPERM: operation not permitted, unlink 'Path\Docume nts\AngularProjects\my-sample-app333\node_modules.staging@angular\core-a3d1aa4 8\ bundles\core.umd.js
I run: npm install -global @angular/core
and it fixed it for me! Finally!!
回答5:
Just try npm cache clean quick and simple :)
回答6:
I tried everything above but it did not work for me.
I copied all content of package.json and deleted the file. Then, I created a new file and copied all there and I saved it as package.json
That fixed everything
