When running mypy on your codebase, you might sometimes encounter a similar error:
error: Library stubs not installed for "requests"
You can have a look at the official documentation on how to solve missing imports but the quickest way to solve it is to run the following:
mypy --install-types
You might also stumble across the similar untyped import issue:
module is installed, but missing library stubs or py.typed marker [import-untyped]
In that case, you can just create a mypy.ini file, populated with the following line:
echo "[mypy]\nignore_missing_imports = True" > mypy.ini
