pywintypes.error: (126, 'LoadLibraryEx', 'The specified module could not be found.')

Hello everyone, pip install starknet_py worked fine, with no issues. Also, pycharm sees no problem, but when I try to run python script (any, even just import starknet_py) it throws this error:
Traceback (most recent call last): File "D:\starknet\test.py", line 1, in <module> from starknet_py.net.account.account import Account File "D:\starknet\test.py", line 9, in <module> from starknet_py.hash.address import compute_address File "D:\starknet\venv\Lib\site-packages\starknet_py\hash\address.py", line 4, in <module> from starknet_py.hash.utils import compute_hash_on_elements File "D:\starknet\venv\Lib\site-packages\starknet_py\hash\utils.py", line 5, in <module> from crypto_cpp_py.cpp_bindings import ( File "D:\starknet\venv\Lib\site-packages\crypto_cpp_py\cpp_bindings.py", line 95, in <module> @load_cpp_lib ^^^^^^^^^^^^ File "D:\starknet\venv\Lib\site-packages\crypto_cpp_py\cpp_bindings.py", line 48, in load_cpp_lib CPP_LIB_BINDING = load_cpp_lib_windows(cpp_lib_file) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "D:\starknet\venv\Lib\site-packages\crypto_cpp_py\cpp_bindings.py", line 58, in load_cpp_lib_windows dll_handle = win32api.LoadLibraryEx(dll_name, 0, handle1) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ pywintypes.error: (126, 'LoadLibraryEx', 'The specified module could not be found.')
The same issue in win 10 and win 11, so I guess I am doing smth wrong. Thanks in advance !

UPDATE: It looks like in Linux works fine, however, I would still appreciate if you help with this issue )

Hey, thanks for the open discussion.
Please follow the steps in the installation part of the docs 👌

[ziyuan123]

I also encountered this problem, and I followed the steps in the documentation to install it.
Here are the installation steps:

1. pip install starknet-py
2. install MinGW through chocolatey.
3. add PATH environment variable
4. run 'gcc -v' to makesure it work

this is the example code:

from starknet_py.net.full_node_client import FullNodeClient
node_url = "https://starknet-mainnet.g.alchemy.com/v2/my_node"
full_node_client = FullNodeClient(node_url=node_url)
call_result = full_node_client.get_block_sync(block_number=1)

this is the error:

pywintypes.error: (126, 'LoadLibraryEx', 'The specified module could not be found.')

Process finished with exit code 1

I am running the program on windows 11, python version 3.9. Thank you in advance for your help

Hey guys 👋 the problem has occurred for some time now. Unfortunately we have limited capabilities for testing starknet.py on Windows and hence we have not came up with a single standardised solution to the problem.

I invite you to our 🐍｜starknet-py channel on the Starknet Discord server, a few people have stumbled upon the same problem and managed to make it work in the end.
Maybe we can try to get a unique working solution.

[ziyuan123]

Thank you for your invitation, I will try to find a solution in the community.

On mac i am getting the following issue:
File "crypto_cpp_py/cpp_bindings.py", line 36, in get_cpp_lib_file raise RuntimeError("Couldn't find libcrypto_c_exports") from exc RuntimeError: Couldn't find libcrypto_c_exports

it is related.
