I've had to use this a few times

Pants comes with some built-in defaults, but it doesn't catch everything. Here's a taste of what we've had to do in our repo

python_requirements(
    name="reqs",
    module_mapping={
        "pyzmq": ["zmq"],
        "ipython": ["IPython"],
        "pyserial": ["serial"],
        "pyserial-asyncio": ["serial_asyncio"],
        "python-can": ["can"]
    },
)

The

x.y==1.0

is confusing to me, though. Don't think I've ever seen dot notation in package names. Are you able to

pip install x.y

or only

pip install x

?

But the top-level import package is just

pants

What is the specific

x.y

in the example?

Because you need to be sure that you're using the right distribution name in requirements.txt and the right import name in

import

statements, and they may not be the same

I look at that page. I am sure which section applies to my case : (

thanks guys. I found that the issue of not finding the module is due to another issue. I will post another thread.
