EPERM: operation not permitted, unlink

[ssashok10]

I am getting the similar error when I tried to install with Angular 4.2.4 [ npm i ag-grid --save ]. My node version is 8.4.0 and npm version is 5.4.1. The installation is conflicting something with "fsevents"...I even tried to use the command "npm cache clean --force"...Here is the error,

I'm having the same issue. Latest NPM / Nodejs / Yarn

[andrexx]

It's a known NPM 5.4 issue. Downgrade to 5.3.
npm/npm#18380

[ssashok10]

Hello, This issue is fixed once I cleaned up the node_modules folder completely and re-import all the packages again. I am using NPM 5.4.1. Thank you for your suggestion.

@jishnudev Try to close your IDE and execute again from console.

[rafaelzuckerberg]

@andrexx thanks for your help, in my case I closed all prompt IDE etc and run again its work

[navalkishor3]

Thanks @ssashok10 . It's Resolve after deleting node_modules folder and install all node packages again.

[saleemmalikraja]

try deleting the node_modules and install the dependencies again...!

[timsar2]

close IDE, and reinstall worked for me.

[patelvasu]

1. Run command prompt as Administrator.
2. Ran npm clean cache.
   After run this command and return Error than run .
   ( npm cache clean --force )
3. npm install -g angular-cli

I was able to fix this by running the command prompt/bash as admin and closing VSCode!
Seems like VSCode was locking some files.
Potentially something else could be locking these files for you.
