'Session Start Failed No module named pdfkit' on bench migrate-env python3, ERPN v11

bug

#1

Running bench migrate-env python3 on bench with Frappe and ERPNext on master (v11) completed successfully, but I’m blocked by this error.

I’ve tried bench setup requirements but that didn’t help. I’ll try pip install pdfkit in bench's virtual environment now.


#2

And the pip command didn’t help.

~/frappe-bench$  env/bin/pip3 install pdfkit
Requirement already satisfied: pdfkit in ./env/lib/python3.5/site-packages (0.6.1)
~/frappe-bench$  env/bin/pip install pdfkit
Requirement already satisfied: pdfkit in ./env/lib/python3.5/site-packages (0.6.1)

#3

I ran bench update after this:

This system supports the C.UTF-8 locale which is recommended.
You might be able to resolve your issue by exporting the
following environment variables:

    export LC_ALL=C.UTF-8
    export LANG=C.UTF-8

Click discovered that you exported a UTF-8 locale
but the locale system could not pick up from it because
it does not exist.  The exported locale is "en_US.UTF-8" but it

uncaught exception: boot failed


#6

@snv, I do want to help document this bug, but I do need to get this system ready. If there’s anything you want like the copy of the bench directory and SQL dump, please say so. I’m going to wipe it out and redo it with Python 3 to begin with (there’s a flag for Python 3 in the installation script, right?); I really need to get this system ready by this week at least.

For context, this was setup using the install script (ran with python3 because I thought it’d setup bench with the Python used to run installer) a week before v11 release. After v11 upgrade it worked fine without issue except for Print Format Builder not loading for whatever reason; that’s why I decided to bench setup --reset and change env to python3 to experiment.


#7
  • The one in yellow is a warning the can be ignored.
  • The exception causing boot failure is uncaught. We need to dig deeper to find the cause of the problem.
  • The print format builder issue has already been fixed before 12 days.
  • Let me know how reinstalling goes.

#8

I already did bench update after facing the Builder issue, so I don’t know why it wasn’t fixed in my case. But well, I already broke it so further ponderance is not worth the time.

I shall run install.py with --python python3 argument this time around.
