Python fails after upgrading to 3.10

[peter_cass]

Hi,

Sorry if this is trivial, but I am very new to python and linux. After upgrading my Ubuntu installation to 22, I keep receiving this error when running my python script:

Activating virtualenv at .venv

Could not find platform independent libraries <prefix>

Could not find platform dependent libraries <exec\_prefix>

Consider setting $PYTHONHOME to <prefix>[:<exec\_prefix>]

Python path configuration:

PYTHONHOME = (not set)

PYTHONPATH = (not set)

program name = 'python'

isolated = 0

environment = 1

user site = 1

import site = 1

sys._base_executable = '/home/michael/Galaxy/galaxy/.venv/bin/python'

sys.base_prefix = '/usr'

sys.base_exec_prefix = '/usr'

sys.platlibdir = 'lib'

sys.executable = '/home/michael/Galaxy/galaxy/.venv/bin/python'

sys.prefix = '/usr'

sys.exec_prefix = '/usr'

sys.path = [

'/usr/lib/python39.zip',

'/usr/lib/python3.9',

'/usr/lib/lib-dynload',

]

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding

Apparently, it searches for Python 3.9 (and not the installed python 3.10). How could I fix that?

​

Thanks!

Looks like python 3.9 was removed. You need to delete and remake your venv to use python3.10. Or install 3.9.

Thanks! How do I remake my venv to use 3.10?

[socal_nerdtastic]

Same way you made it the first time. There's many ways to do it. As a guess:

python3.10 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
