.sage does not exist?
I have a student, Mac OS X 10.7.5, installed the 10.6-app, startup takes her to Terminal, whence the server tries to start and give the error IPython parent 'Users/username/.sage' is not a writable location, using a temp directory. then a bunch of alarms and stuff, and OSError: [Errno 13] Permission denied: 'Users/username/.sage'
I tried reinstalling Sage, and got the same problem. How can I help this student?
Oh, and I went to look at the directory Users/username/.sage and it didn't exist on the student's machine.
Looks like permission problem. Is "username" the login name on that computer?
Indeed, the error indicates it's a permission problem. That doesn't indicate how to *solve* the problem. I'm substituting "username" to keep the student's anonymity. The student is a minor.
Does the student have permission to create files in his/her own directory? As a test, can you see whether the student can create *any* files in Terminal in Users/username/? Certainly the file won't exist if the permissions aren't correct to create files. One could try to see what the user and group permissions are for Users/username/, but it's possible that e.g. parental controls might cause this to happen. For Sage to work, one does need that permission at least, I believe.
And what does "$ ls -l /Users/" says?
