Can pip.conf specify two index-url at the same tim

Question

I have tried using pip with index-url in pip.conf. However, i can not make sure that we can get all the necessary python library. So, i want to know if pip support specify more than one index-url in [global] section in pip.conf.

Answer 1

If you want more than one package index you have to use the --extra-index-url

From the pip man page:

   -i,--index-url <url>
          Base URL of Python Package Index (default https://pypi.python.org/simple/).

   --extra-index-url <url>
          Extra URLs of package indexes to use in addition to --index-url.

In pip.conf the name of settings must be put without --. From the documentation:

The names of the settings are derived from the long command line option, e.g. if you want to use a different package index (--index-url) and set the HTTP timeout (--default-timeout) to 60 seconds your config file would look like this:

[global]
timeout = 60
index-url = http://download.zope.org/ppix

So you can add in your pip.conf

extra-index-url = http://myserver.com/pip

Answer 2

In your pip.conf, you will also have to add both of the index hosts as trusted, so would look something like this:

[global]
index-url = http://download.zope.org/simple
trusted-host = download.zope.org
               pypi.org
               secondary.extra.host
extra-index-url= http://pypi.org/simple
                 http://secondary.extra.host/simple

In this example, you have a primary index and two extra index urls and all hosts are trusted.

If you don't specify the host as trusted, you will get the following error:

The repository located at secondary.extra.host is not a trusted or secure host and is being ignored. If this repository is available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with '--trusted-host secondary.extra.host'.

Cheers!

Answer 3

updating radtek 's answer with the new URL to pypi.

It changed to https://pypi.org

So for your pip to be able to fall back to the original pypi server you'll need to add "https://pypi.org/simple" as an extra-index-url while keeping your local server as index-url. Don't forget to add both to your "trusted-host" list

This update is based on the comment of onelaview: "Official PyPI now supports HTTPS so you can specify https://pypi.org/simple/ for extra-index-URL and avoid specifying pypi.org in trusted-host."

So your pip.conf needs to be containing the following:

[global]
index-url = https://somedomain.org/simple
trusted-host = somedomain.org
               pypi.org
               secondary.extra.host
extra-index-url= http://pypi.org/simple <= either one of these is fine
                 https://pypi.org/simple <= either one of these is fine
                 http://secondary.extra.host/simple
