Do you have SAGE_ROOT set permanently to Users/echolalie/Desktop/Sage-6.9.app for some reason? E.g. ~/.bashrc ~/.bash_profile, ..., Also, the "-bash: PS1: command not found" is suspicious. Not a Sage problem, but most likely an issue with your init files. What is $PS1? On Thursday, March

Hi Eric, I finally compiled the source of sage from github, but I got a merge conflict when I added the sagemanifolds branch. I'll post further when I get to the office. Hope you could help me. Cheers. On Tuesday, 29 March 2016 15:51:53 UTC-3, Eric Gourgoulhon wrote: > > Hi Oscar, > > I'm

[sage-support] Re: Sage Crash Report

Hi Volker, I discover that a git repository hosted at github. I was able to compile the source from that repository, which is by the way more updated that the repository advertised at the documentation. Nonetheless, I'm still having problems when trying to compile the sagemanifolds branch...
