[SOLVED] Sagemath is crashing
When trying to open sage (ipython interface) i got
ImportError: No module named backports.shutil_get_terminal_sizeI then tried
sudo pip2 uninstall backports.shutil_get_terminal_size
sudo pip2 install backports.shutil_get_terminal_sizeAnd now i'm getting a crash report:

*** Last line of input (may not be in above history):Unfortunately, i can't reproduce which package upgrade or else caused this breakage.
Does anyone have an idea how this could be fixed?
Edit:
Just found https://bbs.archlinux.org/viewtopic.php?id=226826
The proposed fix work's for me, too.
I should work on my search skills…

Re: [SOLVED] Sagemath is crashing
Update your system and AUR packages: whatever is linking to libgfortran.so.3 needs to be rebuilt.

Re: [SOLVED] Sagemath is crashing
Why are you using pip to install stuff on the root filesystem? That is just calling for trouble. Those packages are available in the official repositories.

Re: [SOLVED] Sagemath is crashing
@arojas: Because the package was said to be installed and i was testing around.
But yeah, i should probably have done
sudo pacman -R python2-backports.shutil_get_terminal_size
sudo pacman -S python2-backports.shutil_get_terminal_sizeOffline
