Problem when loading loadLSST.bash

Support
#1

I have installed LSST software v15.0 several days ago, and it functions normally,
but today an error occured when i start loading loadLSST.bash.

 $ source loadLSST.bash 
 Traceback (most recent call last):
   File "/home/chiba/Research/lsst_stack/eups/2.1.4/bin/eups_setup", line 28, in <module>
     import eups.setupcmd
 ModuleNotFoundError: No module named 'eups.setupcmd'
 
 During handling of the above exception, another exception occurred:
 
 Traceback (most recent call last):
   File "/home/chiba/Research/lsst_stack/eups/2.1.4/bin/eups_setup", line 42, in <module>
     import eups.setupcmd
ModuleNotFoundError: No module named 'eups.setupcmd'
bash: export: setup: not a function
bash: export: unsetup: not a function

Any help will be greatly appreciated.
Thank you.

Can you start a new shell and try again? I think that there must be something odd about your inherited environment that caused it to stop working. Have you updated your .profile in the past couple of days?

Thank you for the reply.
Yes I did try starting it in a new shell, but the problem still exists.
I don’t know about the .profile, so I think I didn’t update that.

In the worst case, I will reinstall lsst again, but I want to know if
I can solve the problem without re-installation.

Thanks

I have reinstalled the software, and it works now.
Thank you for the help anyway.

I recently encountered the same issue. reinstallation, restart, etc did not help. I eventually worked out that it was because I had PYTHONPATH set. Unsetting PYTHONPATH fixed the problem

unset PYTHONPATH worked for me. Also make sure to run a fresh bash shell and check your file system is not exFAT.
