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. 

npm ERR! code EPERM
npm ERR! errno -4048

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.

This might have something to do with local vs. global installation of lerna. For me it helps to run lerna bootstrap, wait for the EPERM error, close the terminal and run lerna bootstrap again.

Another thing that might work is to run lerna clean.

Also watch out for any running scripts - that can lock up some dependencies making you unable to remove them without admin rights. Especially watch scripts.

I'm on Windows using git bash.
