ModuleNotFoundError: No module named 'attr'

the file runs on my friends computer but not mine

the sql code:-

    create user one_art_admin identified by 'Horriblebob11';
    grant all on one_art.* to one_art_admin;
    flush privileges;

CodePudding user response：

It says attr module not found Try to install the module:

     pip install attr

Then run again.

CodePudding user response：

From the looks of Traceback, it is not SQL client issue. It is an error of missing library attr.
