Issue related to sage dev

[Henry Wu]

Hi sage math communities:

I'm currently working on an issue in the sage repo, and all the changes I made is in one pyx. file. Per my understanding of the dev workflow in the sage documentation,

1. If I changed only python files, I can simply restart sage to test 

2. If other files were changed (in this case, pyx file) I need to rebuild sage via "./sage -br".

My issue is, after I successfully rebuild using "./sage -br" command, my machine returned these lines after calling "./sage":

"Traceback (most recent call last):

  File "/home/zhenyuw/sage/src/bin/sage-ipython", line 9, in <module>
    from sage.misc.banner import banner
ModuleNotFoundError: No module named 'sage'"

My machine is wsl ubuntu on windows. I am confused as to what I've missed in this process.

Also, I realize this process of "re-building" is rather time-consuming. Is there other more efficient ways for sage dev testing?

Regards

Henry

Hi so it seems the issue is somehow resolved. From what I've researched, it could be due to one of these reasons:

1. python version incompatible 

2. check the PATH variable and remove some of the questionable PATH variables per the README file. This is a wsl ubuntu on Windows specific issue.

3. the modification is buggy itself, resulting in a build failure

4. The alternative is always to use make build though with longer time
