[Tutor] IOError when importing nose

[Albert-Jan Roskam]

Hi,

I am using nose on my laptop (installed it using sudo pip install nose), but I get the following error, unless I run python as sudo. Why is this happening, and what can I do to solve this problem? Maybe use chown? I uninstalled and reinstalled the package already, but it did not solve the problem.
