How to make setuptools install a wheel containing multiple packages?

问题

Suppose this wheel:

M Filemode      Length  Date         Time      File
- ----------  --------  -----------  --------  -------------------------------------------
  -rw-rw-r--      1358  26-Sep-2018  21:08:40  azure/common/__init__.py
  -rw-rw-r--       327  26-Sep-2018  21:08:40  azure/common/_version.py
  -rw-rw-r--      8737  26-Sep-2018  21:08:40  azure/common/client_factory.py
  -rw-rw-r--       755  26-Sep-2018  21:08:40  azure/common/cloud.py
  -rw-rw-r--      2479  26-Sep-2018  21:08:40  azure/common/credentials.py
  -rw-rw-r--       805  26-Sep-2018  21:08:40  azure/common/exceptions.py
  -rw-rw-r--      6079  26-Sep-2018  21:08:40  azure/profiles/__init__.py
  -rw-rw-r--      3943  26-Sep-2018  21:08:40  azure/profiles/multiapiclient.py
  -rw-rw-r--         6  26-Sep-2018  21:21:54  azure_common-1.1.16.dist-info/top_level.txt
  -rw-rw-r--       110  26-Sep-2018  21:21:54  azure_common-1.1.16.dist-info/WHEEL
  -rw-rw-r--      3805  26-Sep-2018  21:21:54  azure_common-1.1.16.dist-info/METADATA
  -rw-rw-r--       997  26-Sep-2018  21:21:54  azure_common-1.1.16.dist-info/RECORD
- ----------  --------  -----------  --------  -------------------------------------------
                 29401                         12 files

It has three different packages in it:

azure.common
azure.profiles
azure_common

All great names, and great layout. Also, a lot of greatness of mind that unmistakably went into engineering this miracle of modern software engineering.

This wheel is distributed by the name azure-common. So, when you depend on in in setup.py like this:

setup(
    ...
    install_requires=['azure-common'],
    ...
)

You will only get azure_common package installed. Maybe. I don't really know, it seems so, but few times that I tried it seemed to only install azure.common, or maybe I eyeballed it... It's really hard to follow all the manipulations setuptools does on a package.

Hence the question: how can I force setuptools into installing all packages found in this kind of wheel? Also, the order is important because this garbage needs to be installed some of the times with other packages which also provide azure.something packages which may overwrite the stuff in azure directory. So, Ideally, I'd also like to control in which order install_requires dependencies are processed.

This is where this started: How to specify bracket dependencies in setup.py?

回答1:

It sounds like only few sub-directories like azure.common installed into your environment when you installed dependencies via setup.py with install_requires=['azure-common']. I tried to reproduce this issue, but failed that all files in this package has been installed.

Here is my steps on my local Windows machine as below, which you can refer to.

Create a directory mkdir setuptmp, and create a virtual environment virtualenv setuptmp, then to cd setuptmp.

Create a setup.py file with the content as below.\

from setuptools import setup, find_packages  

setup(
    name = "setuptmp",
    install_requires = ['azure-common']
)

Activate the virtual environment via Scripts\activate.bat.
Run python setup.py install to install the dependency described in my setup.py.

Run python to open the REPL interpreter to test all packages as you said,

(setuptmp) D:\projects\setuptmp>python

>>> azure.profiles.__file__
'D:\\projects\\setuptmp\\lib\\site-packages\\azure_common-1.1.16-py3.7.egg\\azure\\profiles\\__init__.py'
>>> import azure_common
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'azure_common'

Note: azure_common is not a module, just an egg info directory.

Check the packages installed in my environment via cd Lib\site-packages, dir and tree azure_common-1.1.16-py3.7.egg /F as below.

        requires.txt
        top_level.txt
        WHEEL

Compare the above with the file structure of azure-common package downloaded from the link of Pypi website. I decompressed azure_common-1.1.16-py2.py3-none-any.whl file using 7-Zip into a temp directory and tree it.

D:\tmp>tree azure_common-1.1.16-py2.py3-none-any /F
Folder PATH listing for volume Data
Volume serial number is BA4B-64AA
D:\tmp\AZURE_COMMON-1.1.16-PY2.PY3-NONE-ANY

│  │      client_factory.py
│  │      cloud.py
│  │      credentials.py
│  │      exceptions.py
│  │      _version.py
│  │      __init__.py
│  │
│  └─profiles
│          multiapiclient.py

└─azure_common-1.1.16.dist-info
        METADATA
        RECORD
        top_level.txt
        WHEEL

Then, you will find the file structure of step 6 & 7 is almost same.

Hope it helps. If you have any concern, please feel free to let me know.

I did the same above on Linux and got the same result. I saved the output of tree lib/ > lib_[before|after].txt of my Linux setuptmp before and after run python setup.py install, then to compare them using diff lib_*.txt as below.
