I've been using Sagemath on my computer (windows 10) for a long time, but today I found that sagemath Notebook9.0 or 9.3 all crash. I looked at the following information returned by sagemathshell. It doesn't seem normal. I don't know how to solve it. Even if I reinstalled it, it didn't work.

sagemath 9.2 notebook:

Could not find platform independent libraries <prefix>Could not find platform dependent libraries <exec_prefix>Consider setting $PYTHONHOME to <prefix>[ :<exec_prefix>]

Could not find platform independent libraries <prefix>Could not find platform dependent libraries <exec_prefix>Consider setting $PYTHONHOME to <prefix>[ :<exec_prefix>] Fatal Python error: initfsencoding: Unable to get the locale encodingModuleNotFoundError : No module named 'encodings ' Current thread oxe000000800018040(most recent call first): [main] python3 1975 cygwin_exception: : open_stackdumpfile: Dumping stacktrace to python3.stackdump

sagemath9.3shell:

*Don't forget to exit when you are done. Beware:

Do not do anything with other copies of Sage on your system. * Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.

Bypassing shell configuration files...

Note: SAGE_ROOT=/opt/sagemath-9.3

Hi @licheng I will give you the advice to rather do the installation of SageMath under W10 with WSL2 Ubuntu 20.04, follow the instructions below. this will allow you to have 2 shortcuts on your W10 desktop one for Jupyter notebook and the other for Jupyter Lab. Sandy Scott site look also here: Additional Information

I add a summary of the commands to install SageMath with Jupyter notebook only, it's just a simple extraction of the commands from Sandy Scott's site (without Jupyter Lab) below:

Close ubuntu then reopen it.

the only disadvantage of this method is that the make command can take a very long time, for example 6 hours on one of my old PCs and less than 3 hours on my new PC!.

Thank you for your kind advice. Recent lagging updates to Sagemath for Windows have made me worry about not offering a Windows version of Sagemath in the future.

where the sage files are located with ubuntu20.04 WSL2 :

C:\Users\jean-pierre\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu20.04onWindows_79rhkp1fndgsc\LocalState\rootfs\home\ortollj\.sage

where ubuntu.exe is located (for me Ubuntu2004.exe !):

C:\Users\jean-pierre\AppData\Local\Microsoft\WindowsApps

ortollj ( 2022-05-21 19:06:46 +0200 )edit

install WSL2 doc

you can speed up the make , I have 16 cores so I use make -j32 and the make only lasted half an hour !. as @slelievre told me in this post
