Could not find compiled pymongoarrow.lib extension, please install about mongo-arrow HOT 7 CLOSED

Hi @Alan-MTuring, which operating system are you using? Can you also give the full traceback?

from mongo-arrow.

Hey,
I have the same problem on Windows 10. Here is the full traceback I get:

C:\Users\Sebi\anaconda3\lib\site-packages\pymongoarrow_init_.py:34: UserWarning: Could not find compiled pymongoarrow.lib extension, please install from source or report the following traceback on the issue tracker:
Traceback (most recent call last):
File "C:\Users\Sebi\anaconda3\lib\site-packages\pymongoarrow_init_.py", line 32, in
from pymongoarrow.lib import libbson_version
ImportError: DLL load failed while importing lib: Das angegebene Modul wurde nicht gefunden.
warnings.warn(

Seems like the init function cant find the pymongoarrow.lib file but it is in the pymongoarrow package folder.
Thanks for the help :)

System: win11, amd; python version: 3.79. In addition, I use another computer: Windows 11,intel; python version: 3.10. It works perfectly. I recommend writing more demo files to make it easier for beginners

I tried the following on win 10 intel 64bit with both Python 3.7 and Python 3.10 downloaded from python.org. In both cases it worked fine.

python -m pip install pymongoarrow
python -c "import pymongoarrow.lib"

@SebastianSchuhbauer are you on an amd or intel machine? You can check with wmic cpu get name.

Also, it would be helpful to know how you both installed Python in the case where it is not working.

Hey blink,

I am working on an intel machine and my python 3.9.13 got installed together with Anaconda3 2022.10. When using the code you posted I get for:

python -m pip install pymongoarrow

the error mentioned above and if I want to import the lib manually with:

python -c "import pymongoarrow.lib"

I get a similar error, the module cannot be found.

I found the underlying problem, and opened https://jira.mongodb.org/browse/ARROW-121 to track the fix.

Closing as fixed by #97. Please re-open an issue if the error persists after the 0.6.0 release (early next week).
