通过pip安装后，Python模块路径不同

Question

Suppose I am working on a python project named mymodule, and that I have the following directory structure:

mymodule/
   README
   setup.py
   mymodule/
      __init__.py
      foo.py
      bar.py

During development I normally work out of the inner mymodule folder with all of the source files in it. Because of this, if I was working on foo and wanted to import something from bar , I would do something like this:

from bar import myfunction

Everything works fine during development. The problem arises when I want to deploy my module. If I install the module into another project I'm working on, my code no longer works because the modules need to instead be imported like this:

from mymodule.bar import myfunction

I could change all of my imports in mymodule to use this format, however that would mean the module would no longer work in development. When I fix the code for deployment, I break it for development, and vice versa.

What am I doing wrong?

Answer 1

I'm not sure if this is the cleanest way, but I ended up just prefixing all my imports with mymodule. . If I need to develop locally, I just run pip install . in the root directory. If I make any changes, I need to uninstall and reinstall, but at least it works. I'm sure there's some PATH trick that would prevent me from having to do this.

Hope this helps
