i installed sagemath 8.4 on Windows 10. as normal user (no admin rights) when i try to start sagemath 8.4 or sagemath 8.4 Shell or sagemath 8.4 Notebook i get

   mkdir: das Verzeichnis „/home/sage/.sage//R“ kann nicht angelegt werden: Permission denied
    /opt/sagemath-8.4/src/bin/sage-env: Zeile 485: /home/sage/.sage//R/Makevars.user: No such file or directory

when i start as admin than sagemath 8.4 Shell or sagemath 8.4 Notebook dit work. sagemath 8.4 will produce:

--> 136                 os.rename(path, new_path)
    137             else:
    138                 # Otherwise, simply create the new path.
OSError: [Errno 21] Is a directory

"For the moment" is getting funny after nearly 5 years. is it such a big problem?

Problem is solved by deleting the directories .sage and .local

Hi i installed sagemat 8.4 on Windows 10 (as admin) SageMath Shell: sage-sethome "D:\frank\OneDrive\SageMath" SageMath Notebook (Jupyter) is working SageMath (sage): [Errno 21] Is a directory

What can i do? thank you regards frank

hi, in sagemath cloud i multiply a inequality with -1. i expected that the operator change from > to <. but it dit not!

my input:

reset();var(x)
ie = (x>1); show(ie)
show(solve(ie,x))
ie = ie*(-1); show(ie)
show(solve(ie,x))

i dit the solve() to see that the multiplication with -1 results in another solution, which is wrong.
