Issues with installation of python packages with Ansible pip module

I'm facing some interesting voodoo when I try to install python packages with Ansible using its pip module.

Here goes... If I try this:

$ sudo pip install sh

The sh package installation succeeds with no errors at all. That's is a good thing. I will undo this:

$ sudo pip uninstall sh

The next thing I will try is using Ansible:

$ ansible smith pip -a 'name=sh state=present extra_args="-i http://host:port/simple"' -i inventory

This fails. The error message is as follow (forgive me but I am working under firewalls with no internet access so I had to type it. I filtered thing that I didn't think would be necessary - if something is still missing tell me and I will update my question):

smith | FAILED >> {
"cmd" "/usr/local/bin/pip install -i http://host:port/simple sh",
...
msg: stdout: Collecting sh

Naturally, I added to the last command --sudo:

$ ansible smith -m pip -a 'name=sh state=present extra_args="-i http://host:port/simple"' -i inventory --sudo

This time I was speechless. It failed again:

smith | FAILED >> {
"cmd" "/usr/local/bin/pip install -i http://host:port/simple sh",
...
msg: stdout: Collecting sh
Could not find a version that satisfied the requirement (from versions: ) No matching distribution found for sh

Very weird. This goes for all python packages I am trying to install.

Additional information: We have a pypi server where we put all our packages to install. It is under host:port/simple

Also we use this pip.conf file:

[global]
index-url = http://host:port/simple
trusted-host = host

Thanks in advance to all helpers.

Solution

  • OK, I understood what was going on.

    The problem was that my pip.conf file was just for my user (under /home/user/.pip/pip.conf)

    I moved it to /etc/pip.conf and the problem solved.

    An alternative solution wast to add to the arguments --trusted-host host I worked with old version of pip for very long time and when I upgraded to the latest version I forgot to update the arguments.

    Cheers!
