Session Start fail on web

RyanSmith · January 16, 2022, 5:17pm

One problem remains after updating to v13: Upon logging in, the page that opens presents a pop-up which simply says:

module 'public' has no attribute '__file__'

Updated the usual way, several sites (multi-tenant). All upgrades were done, a few issues cropped up but were resolved thanks to help on this forum, and the final updates and migrations all seemed to go without a hitch - except for the above error.

I’ve searched the forum and Google, and while one other post encountered the same error, it did not get any feedback and the person got rid of it by reinstalling the whole system. I can’t do that currently and prefer to know what causes it. I’ve looked through the node modules, I do not find anything named “public”. Either way I removed all and reset with “bench setup requirements”, which completed fine.

This error is not site-specific, it happens for ALL the sites.

Any advice where to find or update or fix that without needing to reinstall all of Frappe/ERPNext?

Could you share the browser console log output when this message pops up?

RyanSmith · January 16, 2022, 6:09pm

Certainly - Apologies, I should have included that from the start:

Are you on the dev branch of bench?

Unsure, but try this:
bench build && bench clear-cache && bench restart

If possible, post the output of the command.

I also got some dependency warnings when rebuilding npm, at least using the bench setup socketio (as part of the list of things I went over to try fix it).

I did not run the fix for it yet since I did not manually do this setup, just let bench do its update steps.

Seems like you’re still on Python 2. You will have to migrate to Python 3.

bench migrate-env python3

I recommend you not to run this on production server, rather, do it on a backup/dev server and see if it migrates without any issues.

RyanSmith · January 16, 2022, 7:11pm

Is there something else I should do also?
I did the migration and it reports success, but then ran bench setup requirements directly after and it still looks like it is using python 2 - see log:

Could be because py2 might be the default version on your system. python --version can confirm that.

But again, that shouldn’t have been an issue since the venv is py3. Strange. Maybe try changing default to py3?

RyanSmith · January 16, 2022, 8:58pm

If I change the default python on my system to python3 then yum breaks completely - so that’s not an option.
The python3 in the virtual environment seems happy by itself after migrating, but it seems the bench command still invokes python 2. What I did learn from this exercise is that even when the system default was changed to python3, the bench still invoked python 2, as if it gets it from somewhere else.

I’ve now run out of time so probably have to try re-install everything.
What is the best way to clean reinstall bench and the frappe and erpnext apps?
Just delete all the files and re-run all the installs?

smino · January 16, 2022, 10:49pm

Hi,

I may have missed it , may we know the operating system and version ?

RyanSmith · January 16, 2022, 11:13pm

You did not miss it, I neglected to say - Apologies - It’s CentOS v. 7

RyanSmith · January 16, 2022, 11:19pm

It is solved now. It seems two things were missing from the updates, either is not correctly in the GIT repo, or doesn’t update with the version-13 branch (which I use), or perhaps simply failed for me.

Switching to my python env from my bench apps folder with:

$ source env/bin/activate

Then installed these two somehow missing modules:

(env) ... $ pip install atpublic

and

(env) ... $ pip install utils

Then did the usual bench setup requirements, bench update --patch, etc. and after completion it all worked.

Thank you kindly for the assistance offered.

rtdany10 · January 17, 2022, 4:13am

Glad it worked out for you. Could you also share how you found the issue so that it’ll be helpful for someone facing similar problems in the future?

RyanSmith · January 17, 2022, 7:17pm

Certainly, though I thought it was clear from my last post already - but quite happy to elaborate some.

The problem manifested in seeing a web-page pop-up claiming “module ‘public’ has no attribute ‘file’”, and during building bench I also received an error that ended with “no module ‘utils’ found”.

Both of these seemed like Python error messages (and indeed were), so I had a long battle with the help of people here to try and sort out my Python version correctly, both for my system and the bench Python environment.

After several back and forwards on that (as can be read above in this thread) I did manage to ensure the Python versions were installed and updated correctly, but still the error remained.

I then tried to google which Python modules could be known as “public” and “utils”, or cause errors named so, and which Python versions they are from. This search led me to Python modules called “atpublic” and “utils” respectively, so I entered the Python environment on my server, and there installed those two modules with the command-lines mentioned in my previous post.

After that I exited the environment, re-did the bench compile and updates, and then it all worked.

I do not know why the modules “utils” and “atpublic” did not install with the bench preparation, I did several deletes and resets of the git files. Perhaps those modules are universal and my server just did not have them (I do run a somewhat barebones version of CentOS). If they are in the git repo and part of the bench initialization, then I do not understand why they were absent for me, but it’s probably worth looking into it.

I did find another post complaining of the exact same thing, but nobody could help him either and that person’s solution seems to have been solved with a full server re-install.

Either way, I hope if anyone else encounters this problem, my fix-steps above and in the previous post would be helpful to them.
