Buildout - Allow hosts for package download

Question

I have a Plone 5.0.5 deployment and the need the package zc.zrs for ZODB replication. After adding the information to the buildout.cfg, I've added the URL https://pypi.org/simple on the index parameter:

[buildout]
extends = 
    base.cfg
    versions.cfg
index = https://pypi.org/simple

Then I run the buildout and get the following error:

# sudo -u plone_buildout bin/buildout

Installing 'plone.recipe.zeoserver[zrs]'.
We have the distribution that satisfies 'plone.recipe.zeoserver[zrs]==1.2.9'.
Getting required 'zc.zrs'
We have no distributions for zc.zrs that satisfies 'zc.zrs'.

After doing some research find out that the buildout uses easy_install, and tryed to add some parameters described from this documentation , but I'm getting the same errors like doesn't changed nothing.

How can I allow the download from PyPI from Plone buildout?

Answer 1

The Plone buildout should be able to download from pypi by default. Check if you can download with wget into your download folder:

wget https://files.pythonhosted.org/packages/5c/b2/5a516f4883fc766ea37a9d979a5cacddc1b29df17140c14da26676a3c4b5/zc.zrs-3.1.0.tar.gz

You should have a downloads folder in your buildout-cache folder, if you are using the default installer. I do that sometimes when the server has some strange.network configurations and can't download some packages directly.
