ModuleNotFoundError: No module named 'ibm_db_dbi'

[KlausPeterLuttkus]

Hi @ all,

I have a problem executing bob makei command:

Traceback (most recent call last):
File "/QOpenSys/pkgs/lib/bob/src/makei/cli/makei_entry.py", line 12, in
from makei.cvtsrcpf import CvtSrcPf
File "/QOpenSys/pkgs/lib/bob/src/makei/cvtsrcpf.py", line 7, in
from makei.ibm_job import IBMJob
File "/QOpenSys/pkgs/lib/bob/src/makei/ibm_job.py", line 10, in
import ibm_db_dbi
ModuleNotFoundError: No module named 'ibm_db_dbi'

I tried what arco400 did to solve the same problem. But to no avail.

My environment

• bob 2.4.31-1
• python39-ibm_db 2.0.5.15.1
• python39-itoolkit 1.7.0.1
• source-orbit 1.0.2

Can anyone help?

Regards

Have you installed python39, which is separate from phython39-ibm_db?

[KlausPeterLuttkus]

This is my python environment:

As far as I understand it, it's everything python.

[KlausPeterLuttkus]

So far no solution to problem.

I extented my checks:

I checked default version of python

update-alternatives--config python

Selection Path Priority Status

0 /QOpenSys/pkgs/bin/python3.13 313 auto mode
1 /QOpenSys/pkgs/bin/python2.7 207 manual mode
2 /QOpenSys/pkgs/bin/python3.13 313 manual mode
3 /QOpenSys/pkgs/bin/python3.6 306 manual mode

• 4 /QOpenSys/pkgs/bin/python3.9 309 manual mode

I called python in interactive mode:

python
Python 3.9.20 (main, Nov 5 2024, 10:59:51)
[GCC 6.3.0] on os400

This verified that python39 is default.

I imported module ibm_db:
ibm_db.version
'2.0.5.15'

I imported module ibm_db_dbi
ibm_dbdbi.version
'2.0.5.15'

This shows that everything is in place. What am i missing?

Any help would be apreciated!

Could you try to downgrade python39 to 3.9.18 from 3.9.20? Right now, the build spec appears to mention that version specifically, so that may be an issue?

From the spec file:

BuildRequires: make-gnu
BuildRequires: tar-gnu
BuildRequires: gzip
BuildRequires: bash >= 5.1-2
Requires: bash >= 5.1-2
Requires: coreutils-gnu >= 8.25-5
Requires: sed-gnu >= 4.4-1
Requires: grep-gnu >= 3.0-2
Requires: gawk >= 4.1.4-2
Requires: make-gnu >= 4.2-2
Requires: python39 >= 3.9.18
Requires: python39-ibm_db >= 2.0.5.12

[KlausPeterLuttkus]

Thanks a lot bmcpherson-srlife, but there is no package python3.9.18 in IBM's repository.

First try:
-bash-5.2$ yum downgrade python3.9.18-1
Setting up Downgrade Process
No package python3.9.18-1 available.
Nothing to do

Second try:
-bash-5.2$ yum downgrade python3.9.18
Setting up Downgrade Process
No package python3.9.18 available.
Nothing to do

Third try:
-bash-5.2$ yum downgrade python39
Setting up Downgrade Process
Only Upgrade available on package: python3.9.20-1
Nothing to do

Btw. requirement for python39 is 3.9.18 or greater. therefor all requirements are met:

BuildRequires: make-gnu ok
BuildRequires: tar-gnu ok
BuildRequires: gzip ok
BuildRequires: bash >= 5.1-2 ok 5.2.1
Requires: bash >= 5.1-2 ok 5.2.1
Requires: coreutils-gnu >= 8.25-5 ok 9.5.3
Requires: sed-gnu >= 4.4-1 ok 4.4.2
Requires: grep-gnu >= 3.0-2 ok 3.0.3
Requires: gawk >= 4.1.4-2 ok 4.1.4-2
Requires: make-gnu >= 4.2-2 ok 4.4-1
Requires: python39 >= 3.9.18 ok 3.9.20-1
Requires: python39-ibm_db >= 2.0.5.12 ok 2.0.5.15

[bmcpherson-srlife]

I apologize that I have not been able to provide you a solution. As seen in the screenshot I had posted before, the Python version I am running on my system is 3.9.18-1, so I was hoping that would still be available. The only other thing I can think to try, which I'm sure you have at this point, is uninstall Bob and its components and download Bob again to see what it pulls in and if it will correct itself.

@edmundreinhardt , do you have any insight into what might be occurring here?

[edmundreinhardt]

I have not tried with 3.9.20 yet. Conceptually I can't think of a reason it would break, I did upgrade to 3.9.18 just to keep depend-a-bot happy.

[edmundreinhardt]

@SanjulaGanepola or @irfanshar we should upgrade one of our machines and see if it handles it.
@ThePrez do you have any idea why the ibm_db_dbi would not load?

[ThePrez]

Everything checks out in terms of the environment. A yum reinstall python39-ibm_db would be worth a shot. Perhaps @abmusse would have some pointers

[KlausPeterLuttkus]

@ALL Thank's for caring. @ThePrez reinstall did not solve the problem.

[edmundreinhardt]

@abmusse could you please weigh in here?

[abmusse]

Hello everyone,

@KlausPeterLuttkus

What is /QOpenSys/pkgs/bin/python3 pointing to?

ls -l /QOpenSys/pkgs/bin/python3

[arco400]

Hi Klaus-Peter, On our system we have the same python versions installed and so far I have not encountered this error. But I have only 3 packages installed. python39 3.9.18-1 python39-ibm_db 2.0.5.12-1 python39-six 1.16.0-2 Your python packages list is way bigger, could one of them be the cause?

@abmusse Thank's a lot, you nailed it!

Python3 symlink pointed to python version 3.13.
In the past I had done an update-alternatives --config python and had sat python3 as default. But still python3 simlink pointed to version 3.13.
Because of your post I did an update-alternatives --config python3. Here the default pointed to version 3.13. I changed the default to version 3.9. After that makei worked like a charm.

Maybe the documentation should be extended concerning this problem.

Thank yous to @ALL for helping me. You're great!
