# Calling Mathematica gives 'Read-only file system'

When I try to call Mathematica for anything (`mathematica('1')`

), it comes back with

```
OSError: [Errno 30] Read-only file system: '/export/pkgs/linux-rh6/sagemath-6.3/local/share/sage/ext/mathematica'
```

Is there anything I can do to remedy this?

Calling `math`

from the command line will open Mathematica.

If you are using sage 6.3, you should first update to the latest release 6.8.
