Hi @chad-upton are you able to provide any other information on where this might be occurring?

[Jinkxed]

It was the only module being installed, not sure which method it was happening on. I ran puppet with -vd and it reported the same.

I actually went another way in doing what I needed and ended up not using this module.

I'm getting this as well. Debug gives this just before.

I'm using PE 2017.3.2, on CentOS 6.9, and I am pulling supervisord directly from github.

Ok, I think I figured it out. The version of pip that easy_install was installing, is broken. Once I installed the python-pip package via yum, it moved on past that point. I've set install_pip to false and I'm handling that install elsewhere.

@damonconway I realize this was a while ago, but could you articulate this fix in any more detail? Did you edit the .pp files to remove the easy_install calls or just install pip via SSH and it skiped them on it's own?

[damonconway]

I left the company where I was working on that code later that year so I can't go look. However, I believe I added some code to one of my pp files that made sure pip was installed via yum. That bypassed the check that was failing.
