I installed the python 3.8 version. and Syntex error is solved but now

ubuntu@tecis_erpnext:/home/frappe/frappe-bench$ bench start
Traceback (most recent call last):
  File "/home/ubuntu/.local/bin/bench", line 5, in <module>
    from bench.cli import cli
ModuleNotFoundError: No module named 'bench'
ubuntu@tecis_erpnext:/home/frappe/frappe-bench$

You have to re-install frappe-bench

pip3 install --install frappe-bench
or
pip3 install --upgrade frappe-bench

?

and
bench setup requirement

The fact is your hosting system do not have bench install correctly as now you change/re-install version of python.

You can find on this forum a lot’s of tutorial to How install Frappe Bench and so one, you should read them first.

You have update to 3.8 but the require for version-14 is 3.10 at least.

There is obviously a problem with your python and bench install…

I think this is not specifics to Frappe or Bench but more related to Linux and Python system management. I can’t help you more on that, but I’m sure you can dig a little bit with this forum and Python documentation to find out what is going on.

Hi

The desired Ubuntu release is Ubuntu 22.04.1 LTS

python3 -V should return Python 3.10.4

node -v v14.20.0

bench --version 5.14.2

bench version erpnext 14.0.2
frappe 14.4.2

I might try sudo pip3 install frappe-bench --upgrade once the above is in place , then

bench switch to branch version-14 frappe erpnext and bench update --patch

Hey Jay,

Just format your system and install the tools with versions specified below. Alternatively, as @FHenry mentioned, use any guide on this forum and you should be good to go.
