Thanks for the advice Tim,
I also found this solution for the particular case of branch switching: http://codeinthehole.com/writing/a-useful-git-post-checkout-hook-for-python-repos/
Best,
Lucia

Speaking of which, I tend to:
export PYTHONDONTWRITEBYTECODE=true
... in all my development virtualenvs to just disable .pyc files entirely. Between the reloader and everything else, recompiling the bytecode each time is a very small penalty for the quality of life improvement.Â

Hi Tim
The issue were caused by some .pyc files that are ignored by git and therefore not deleted when switching branches.
I deleted all the .pyc, reinstalled the extensions and now it works as before.
Thanks,
Lucia

Hi Tim
I guess I did not unistall something properly as you said.
I switched to the latest branch, install the new requirements (pip install).
As it didn't work, I switched back to my branch with version 2.5.2 and re-installed the requirements.
Is there something else I can do to get back to my previous state? Is this a problem related to the virtual environment?
Thanks a lot,
Lucia

Yes Lucia, Config has changed.
ckan.common.config is the new config library
pylons.config is the 2.5.2 library
SO looks like you still have some 2.6 / 2.5.3 (?) code/files floating about. Did you actually uninstall or just install on top of the latest branch?

Dear all
I had a working instance of CKAN v. 2.5.2.
I tried the latest version in the git repository just for testing but it failed so I went back to my 2.5.2 branch.
Now I cannot restart the instance, I installed again the requirements in the virtual environment but I keep getting this ImportError error below.
Does anyone know what can I do?
Thanks a lot,
Lucia
