no, pypi.python.org is behind Fastly CDN:

$ host pypi.python.org
pypi.python.org is an alias for prod.python.map.fastly.net.
prod.python.map.fastly.net has address 151.101.92.223

I had a similar issue this morning:

attempted to run

docker run -p 8080:8080 -e PLONE_ADDONS="rapido.plone" plone fg

and got the following output:

works as expected.

seems like a setuptools/buildout issue; I added some debug in out Travis build and it seems buildout is not downloading wheels:

UnsupportedWheel: zc.recipe.egg is in an unsupported or invalid wheel

https://travis-ci.org/plonegovbr/portal.buildout/jobs/293662255

seems a known issue:

the workaround is:

$pip install zc.recipe.egg --no-cache-dir

Hi. I just figured out how to solve the issue. Go into your Plone directory, then lib/python2.7/site-packages/zc/buildout and change http to https in the file easy_install.py. Now my buildout is able to find packages again.

Need to update zc.buildout to 2.9.5 version to fix it

Well, it seems that all buildouts will fail if you don't already have your eggs downloaded in a cache folder and are using zc.buildout <= 2.9.5. That's why you won't see this error if you already have an environment but it's in CI.

Assuming your python is already a virtualenv, you can run for example:

git clone https://github.com/collective/minimalplone4 && cd minimalplone4 && wget https://bootstrap.pypa.io/bootstrap-buildout.py && python bootstrap-buildout.py && mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs" versions:zc.buildout=1.7.1

You will get the error:

Couldn't find index page for 'plone.recipe.zope2instance' (maybe misspelled?)
Getting distribution for 'plone.recipe.zope2instance==4.3'.

  Installing recipe plone.recipe.zope2instance.
  Getting distribution for 'plone.recipe.zope2instance==4.3'.
Error: Couldn't find a distribution for 'plone.recipe.zope2instance==4.3'.

Trying from 1.7.1 to all new buildout versions fail, it works only when we are in 2.9.5. Try for yourself:

git clone https://github.com/collective/minimalplone4 && cd minimalplone4 && wget https://bootstrap.pypa.io/bootstrap-buildout.py && python bootstrap-buildout.py && mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs" versions:zc.buildout=2.9.5

The magic is this commit: https://github.com/buildout/buildout/commit/fac9979f516fe1b080258f9b367401a8cc1832e8#diff-db23dcd814354c954091a9b90dbfd92a funny though that if I add index = https://pypi.python.org/simple in my buildout it doesn't work, I need to upgrade zc.buildout to 2.9.5.

FYI @hvelarde and @mauritsvanrees
. I think a change in https://github.com/collective/buildout.plonetest pinning zc.buildout is needed with this justification. More implications in Plone will come, that's why I'm posting it here. Maybe https://github.com/plone/Products.CMFPlone/issues/1502 will need to be revisited.

The easiest fix without updating zc.buildout for more recent zc.buildout and setuptools versions is to create/modify your buildout config or the default.cfg (on unixes in ~/.buildout/default.cfg) and add under the [buildout] section:

index = https://pypi.python.org/simple

So that https is used for index access.

Adding this to my buildout didn't work.

Do you have shared eggs directories? Did you try to add to a CI configuration?

@idgserpro I just spotted your line where you noticed adding index = doesn't work, for me it does, but with zc.buildout 2.8.0 in my buildout(s). Weird indeed.

Jenkins build jobs will start to fail now as well where bootstrap.py is run.

If you use a bootstrap.py for zc.buildout version 1.x, you probably have a wrong ez_setup.py url. For coredev 4.3 I have fixed it here:

https://bootstrap.pypa.io/bootstrap-buildout.py is already using https://bootstrap.pypa.io/ez_setup.py. At least in the Plone 4 tests I made above, I don't think it's related.

Coredev 4.3 uses a bootstrap.py that installs zc.buildout 1.x. It is this one, which has the old ez_setup url:

http://downloads.buildout.org/1/bootstrap.py

I made a pull request for updating it at https://github.com/buildout/buildout/pull/419

Oh, for those who cannot reprocuce the bootstrap error locally, try using a virtualenv without setuptools, otherwise the failing part gets ignored:

  virtualenv --no-setuptools --no-pip --no-wheel --python=python2.7 .

Using your commit in https://github.com/plone/buildout.coredev/commit/316da91ced540273bc161987b43423955ee5d8c7:

git clone https://github.com/collective/minimalplone4 && cd minimalplone4 && wget https://raw.githubusercontent.com/plone/buildout.coredev/316da91ced540273bc161987b43423955ee5d8c7/bootstrap.py && python bootstrap.py && mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs" versions:zc.buildout=1.7.1

Gives the same error:

Couldn't find index page for 'plone.recipe.zope2instance' (maybe misspelled?)
Getting distribution for 'plone.recipe.zope2instance==4.3'.
While:
  Installing.

Error: Couldn't find a distribution for 'plone.recipe.zope2instance==4.3'.

But we'll try to reproduce like you said in Buildout not working / Couldn't find index page for / Couldn't find a distribution / Disabling non HTTPS access to APIs on PyPI.

If you already has cached eggs, there's no error, that's why we're using mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs", to force it to always download the eggs.

@mauritsvanrees using the virtualenv and different bootstrap (for buildout 1 and 2) we still get the same error if zc.buildout is pinned to any version different from 2.9.5.

@idgserpro: I need the updated bootstrap.py because otherwise the bootstrap call gives an error. After that finishes correctly, and I ignore the eggs cache, I get the same error as you. It works for me when I add this to your last command:

buildout:index=https://pypi.python.org/simple/

This topic is now a banner. It will appear at the top of every page until it is dismissed by the user.

This topic is no longer a banner. It will no longer appear at the top of every page.

I confirm that this solution works for me. I replaced my bootstrap.py with the one at:

https://bootstrap.pypa.io/bootstrap-buildout.py

and added the line in my default.cfg:

index=https://pypi.python.org/simple/

Putting the above line in the [buildout] section of buildout.cfg should work as well.
