Npm 安装错误 EPERM 不允许操作

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" 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

npm install -g npm@latest

Answer 4

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 5

只需快速简单地尝试npm cache clean :)

Answer 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

Answer 7

100% sure

Firstly delete the project folder. eg: myapp1

Then run -> npm cache clean --force command

Retype the command that gives error previously.

Answer 8

macOS catalina ,

            npm init 

got error

       operation not permitted, uv_cwd

step 1: go to parent folder

         cd ../
         

step 2: go to your project folder again,

         cd  your-project-folder

That is it. it works.

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.
