Npm install error EPERM Operation not permitted - node.js

Question

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 :

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.

macOS catalina ,
npm init

operation not permitted, uv_cwd
step 1: go to parent folder
cd ../

That is it. it works.

Try below setps, hope this helps.

Answer 5

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!!

Answer 6

Just try npm cache clean quick and simple :)

Answer 7

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

Answer 8

100% sure
Firstly delete the project folder. eg: myapp1
Then run ->npm cache clean --force command
Retype the command that gives error previously.

Answer 9

I also faced the same issue but once I removed node_modules folder along with package-lock.json from the project and then I re-installed entire thing again with npm i it worked for me.
