I can't get npm install to work in an angular project. The install almost goes through but fails with
npm ERR! code EPERM
npm ERR! syscall unlink
npm ERR! path C:\workspaces\my-project\my-module\node_modules\.staging\typescript-d1902bf5\lib\typescriptServices.js

npm ERR! The operation was rejected by your operating system.
npm ERR! It's possible that the file was already in use (by a text editor or antivirus),

What I've tried:
Running from cmd, git bash and power shell both as a regular user and as admin
Deleting the node_modules folder and retrying
installing nvm for Windows and installing nodejs 12.13.0 LTS (which then installs npm), then trying npm install
uninstalling nvm for Windows and installing nodejs 12.13.0 LTS with the site's installer, npm i -g npm, npm install
excluding my workspaces dir in Windows security settings
npm cache verify, npm install
npm cache clean --force, npm install
Can anyone suggest something I may not have thought of? Unfortunately I can't post my package.json or .npmrc as the repository I'm using is not public but from the looks of the error it should be irrelevant.
Update
It looks like it might be a race condition. See here. I'm using npm version 6.13.0.
Another update
I've got other problems now but Jonathan Irvin's comment helped me, in particular this. I disabled windows indexing and gave all permissions to my user.

Answer 1

try npm unlink on the root directory of the project.
