Can't run snap7 without an environment

[FernandoBarajasValdivia]

I installed snap7 in a jetson nano, using an environmet and it is all okey.

The problem is when i install snap7 without an environment I get next error:

snap7.exceptions.snap7Exceptions: can't find snap7 library. If installed, try running Idconfig

(The install was successful but I can't use it for the error)

Hi @FernandoBarajasValdivia
Can you give more information about your setup?

1. What version of Python are you using? (command: python3 -V)
2. What version of the package is installed? (command: python3 -m pip show python-snap7)
3. What package manager are you using? (pip, poetry, anaconda)

[FernandoBarajasValdivia]

1.- python version= 3.6.9
2.- version of the package:

3.- package manager: pip3

thanks for response!

I've checked a package build for v1.2, looks fine to me.

1. Show your OS version with uname -a command
2. Check if the shared library exists using the ls /home/jetsonoc/.local/lib/python3.6/site-packages/snap7/lib/libsnap7.so command

are you sure you are running on 64 bit arm? can you try to manually install the binary arm64 wheel from pypi

when I try to install python_snap7-1.3-py3-none-manylinux2014_aarch64.whl I receive an error like this:
"python_snap7-1.3-py3-none-manylinux2014_aarch64.whl is not a supported wheel on this plataform" :(

I have got the similar type issue, while installing it and running through docker, i have installed it using "pip install python-snap7" in docker file, this is my error

File "/py/lib/python3.9/site-packages/snap7/common.py", line 63, in init
logic-load | raise RuntimeError("can't find snap7 library. If installed, try running ldconfig")
logic-load | RuntimeError: can't find snap7 library. If installed, try running ldconfig

this is the version that gets installed

And my platform is 64 bit,

Is your issue resolved? Could you please share what the problem was?

[FernandoBarajasValdivia]

I could never solve it, to solve it I installed a virtual environment. So I was able to install the snap7 without problems. But witout the env I couldn't. :(

[FernandoBarajasValdivia]

It was so strange but I solved it.

[nikteliy]

Interesting. Thanks for sharing, this could be helpful. I will try to figure this out.
