DEV\dev-create-jam-package> jam -v

DEV\dev-create-jam-package> jam link .
Error: EPERM, symlink 'C:\Users\mtherrien\Desktop\DEV\javascript-repo\beholdergraph\DEV\dev-create-jam-package'


I don't think you can create symlinks (or something synonymous) on Windows, so this feature is unsupported on that platform. If someone knows better then please help out and send me a pull request ;)

I'll leave this issue open for now, since I think we should have a more friendly error message on platforms that don't support it.


From Windows Vista and onwards there are natively supported symbolic links:
Windows XP had something called NTFS junction points which seem similar (not as powerful) but you needed a third party tool:


@Marrok are you running Vista or later?


Also, does 'npm link' work for you?


@caolan I am Windows 7.
I've only used npm to install jam, so I can't say for sure.

I've experienced the same issue, but it turned out in my case that I didn't have sufficient permissions. Running the same command as administrator worked... (on Windows 7)


Thanks for the tip robmazan! Permissions was the problem
