EPERM: operation not permitted, unlink 'C:\Users\**\node_modules\.node-sass.DELETE\vendor\win32-x64-57\binding.node'

Question

When I run "npm install", I get an error.

OS: Windows 10 npm: 6.2.0 node: v10.9.0

I already tried to "npm install" after "npm cache verify" but I couldn't solved it.

npm cache verify 
npm instal

Try removing the node_modules folder. Then npm install instead of npm instal. — Super Jade

Yep, same goes for if you are running React. I stopped it and it installed fine.

This worked for me. There were "node" processes in windows and I manually end them and it worked.

This usually happens when you are running node and then try to do an npm install in your project.

Check if you are running gulp like gulp build:server or any npm scripts (like npm run xxxx) for your project. Then stop those and you will be able to successfully complete npm install command.

Killed all node tasks from Task Manager(Windows 10) and then again executed the commands. It worked!

I had the same problem, I manually removed .node-sass.DELETE from node_modules

Then run:

npm cache verify

npm install

On Windows, closing Node wasn't enough.

I had to open a shell in Admin Mode and stop all Node and Electron processes.

Here are the four apps I know can lock some files in node_modules directories

stop-process -Name node
stop-process -Name electron
stop-process -Name chromedriver
stop-process -Name chrome          # ChromeDriver can spawn some apps during tests in hidden mode
