Attempted to operate MySQL using Python on Apple Silicon, but encountered the following error:
ImportError: dlopen(/.../site-packages/MySQLdb/_mysql.cpython-310-darwin.so, 0x0002): symbol not found in flat namespace '_mysql_affected_rows'Referring to the comment in the following link:
Macos M1 mysqlclient Symbol not found: _mysql_affected_rows ERROR · Issue #496 · PyMySQL/mysqlclient
In my environment, the output was:
% echo $MYSQLCLIENT_LDFLAGS
-L/opt/homebrew/opt/openssl/lib -L/opt/homebrew/opt/mysql/lib -L/opt/homebrew/opt/zlib/lib -L/opt/homebrew/libSo, I modified it to:
% echo $MYSQLCLIENT_LDFLAGS
-L/opt/homebrew/opt/openssl/lib -L/opt/homebrew/opt/mysql/lib -L/opt/homebrew/opt/zlib/lib -L/opt/homebrew/lib -lmysqlclient -rpath /opt/homebrew/opt/mysql/libAfter that, I executed the following commands:
pip uninstall mysqlclient
pip cache purge
pip install mysqlclientIf there are no errors when executing:
python3
>>> import MySQLdb
>>>then it's OK.
