我的安装了pip install的软件包没有显示模块

Question

I have a simple Python project with effectively one package (called forcelib ) containing one module (also called forcelib ):

- setup.py
- forcelib
  |- __init__.py
  |- forcelib.py

My setup.py is copied from the official example and has the obvious edits.

The problem is that I can install the forcelib package using pip but when I import forcelib , it only has the "double-underscore" attributes visible. That is, I cannot see the forcelib module.

Example to replicate:

1. git clone https://github.com/blokeley/forcelib
2. cd forcelib
3. pip install -e .
4. python
5. import forcelib
6. print(forcelib.__version__) # Correctly prints 0.1.2
7. dir(forcelib) # The only contents are the __version__ , __path__ etc. double-underscore attributes. I had expected to see forcelib , example_read etc.

Perhaps I'm supposed to distribute just the module rather than bother with a package.

The (very small) project is on GitHub .

Any advice would be much appreciated.

Answer 1

It seems that there are 2 ways of doing it:

1. Keep the same directory structure but put the following in __init__.py

   from .forcelib import *

2. Distribute a module, not a package. Follow the instructions to use the py_modules argument rather than the packages argument in setup.py . This would mean restructuring the project to:

   • setup.py
   • forcelib.py

Approach (1) can be seen here . It has the advantage of hiding the private functions and attributes (anything not in __all__ ), but the client can still see the module forcelib.forcelib , which I don't think it should.

Approach (2) can be seen here . It is simpler, but has the disadvantage that it does not hide private functions and attributes.

Answer 2

Download zip file and extract zip after go to forcelib-master directory then open command prompt and go to forcelib-master directory in command prompt and run command

python setup.py install

It will install packages successfully
