operation not permitted error npm while running lerna bootstrap -- hoist command on windows

Whenever I am running lerna bootstrap --hoist or lerna bootstrap I am getting the following error on my windows machine.

I have already tried npm login and force cleaned the npm cache but nothing seems to be working.

lerna.json

{
  "packages": [
    "packages/*"
  ],
  "version": "independent"
}

My Environment

lerna --version 3.5.1

npm --version 6.4.1

node --version 10.5.0

OS Version

Windows 10 1709

Solution

  • I finally found a solution; it seems to be an issue with Windows. Just run the command in an admin command prompt in your current working directory and it would work.
