Additional information

I am trying to run tests in windows, and get a bunch of failures with similar errors

[PoojaDurgad]

running git bash as administrator solves the issue, but not sure if this is the right approach

[mmomtchev]

@PoojaDurgad can you try deleting your whole source tree, then re-clone and rebuild?

[jasnell]

I think the challenge might be related to git bash itself here. Can you build without using git bash?

[lemire]

I get this same error. If we are expected to run the builds under bash, shouldn't this be documented?

[lemire]

The current instructions tell us to use vcbuild.bat, which is a Microsoft batch file. I don't think this will run under bash, will it?

[huseyinacacak-janea]

The node tests need to test creating links. As your user doesn't have permission to create symbolic links, you get an EPERM error. Please follow the instructions below to make sure you have the right to create symbolic links with your user.

1. Find the configuration location stated here.
2. Click on Add User or Group
3. Click on Advanced
4. Click on Find Now
5. Search your user in the list and click on Ok
6. After adding your user, you may need to reboot your computer.
