Angular-cli: 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.

[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

[peng2013]

I am getting the similar error when I tried to install with Angular 6.0. My node version isv8.11.3 and npm version is6.1.0. The installation is conflicting something with "fsevents"...I even tried to use the command "npm cache clean --force"...Here is the error,

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.

[deepakjha14]

Any luck here, I have run into the same proble and its crazy that even after reinstallign node and npm i am getting that error :(

[Rouhollah]

you must checkout this files first, if you are working on source control.
package.json , angular.json, app.module.ts
this way worked for me.

While opening the solution in Visual Studio is locking some configuration files. So sometimes it shows this type of errors. Close the solution opened in VS Code Or any other editor and run the command from cmd prompt will solve the issue.

For running the command from cmd prompt, Just go to your project folder then press Shift + Right-Click then click Open command window here. Then type the npm install...
