After installing MariaDB Connector/Python on Windows 64-bit with Python 3.8.3 I am getting the following error in import mariadb
:
ImportError: DLL load failed while importing mariadb: The specified module could not be found.
Apparently this is a known issue . Could you, please, help me to find a workaround until the issue is fixed?
Listing of venv\app_name\Lib\site-packages\mariadb-0.9.58.dist-info
produces the following results:

Apparently it doesn't look like a lot of useful stuff because there are no Python or C/C++ modules. So perhaps the installation with pip3 install --pre mariadb
has failed silently (nevertheless it reported success).
I have the following candidate solutions in mind:
Apparently the quickest and most reliable solution (as far as I can see) was to build MariaDB Connector/Python from sources by following the steps from wiki , specifically, having MSVS 2019 and MariaDB Connector/C installed, I did the following from within the virtual environment command line:
set MARIADB_CC_INSTALL_DIR="C:\Program Files\MariaDB\MariaDB Connector C 64-bit"
python setup.py build
python setup.py install
This bug was caused by a small typo, instead of linking statically, MariaDB Connector/C was linked dynamically, but libmariadb.dll couldn't be loaded.
