Using an extra python package index url with setup.py

问题

Is there a way to use an extra python package index (ala pip --extra-index-url pypi.example.org mypackage) with setup.py so that running python setup.py install can find the packages hosted on pypi.example.org?

回答1:

If you're the package maintainer, and you want to host one or more dependencies for your package somewhere other than PyPi, you can use the dependency_links option of setuptools in your distribution's setup.py file. This allows you to provide an explicit location where your package can be located.

For example:

from setuptools import setup

setup(
    name='somepackage',
    install_requires=[
        'somedep'
    ],
    dependency_links=[
        'https://pypi.example.org/pypi/somedep/'
    ]
    # ...
)

If you host your own index server, you'll need to provide links to the pages containing the actual download links for each egg, not the page listing all of the packages (e.g. https://pypi.example.org/pypi/somedep/, not https://pypi.example.org/)

setuptools uses easy_install under the hood.

It relies on either setup.cfg or ~/.pydistutils.cfg as documented here.

Extra paths to packages can be defined in either of these files with the find_links. You can override the registry url with index_url but cannot supply an extra-index-url. Example below inspired by the docs:

[easy_install]
find_links = http://mypackages.example.com/somedir/
             http://turbogears.org/download/
             http://peak.telecommunity.com/dist/
index-url = https://mypi.example.com

Found solution when using Dockerfile:

RUN cd flask-mongoengine-0.9.5 && \
    /bin/echo -e [easy_install]\\nindex-url = https://pypi.tuna.tsinghua.edu.cn/simple >> setup.cfg && \
    python setup.py install

Which /bin/echo -e [easy_install]\\nindex-url = https://pypi.tuna.tsinghua.edu.cn/simple will output:

[easy_install]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

The following worked for me (develop, not install):

$ python setup.py develop --index-url https://x.com/n/r/pypi-proxy/simple

Where https://x.com/n/r/pypi-proxy/simple is a local PyPI repository.

As far as I know, you cant do that. You need to tell pip this, or by passing a parameter like you mentioned, or by setting this on the user environment.

Check my ~/.pip/pip.conf:

[global]
download_cache = ~/.cache/pip
index-url = http://user:pass@localpypiserver.com:80/simple
timeout = 300

In this case, my local pypiserver also proxies all packages from pypi.python.org, so I dont need to add a 2nd entry.

You can include --extra-index-urls in a requirements.txt file. See: http://pip.readthedocs.org/en/0.8.3/requirement-format.html
