buildout 找不到 Plone 的 pip 包

Question

我正在尝试通过 buildout 将附加组件添加到 Plone，但它找不到包。我已经在 virtualenv 和系统范围的 python 中尝试过它

我按照 Plone 网站上的设置进行操作 Setup instructions

我尝试的每个插件都会出现以下错误

Installing instance.
/home/a/Plone/zinstance/local/lib/python2.7/site-packages/pkg_resources/__init__.py:192: RuntimeWarning: You have iterated over the result of pkg_resources.parse_version. This is a legacy behavior which is inconsistent with the new version class introduced in setuptools 8.0. In most cases, conversion to a tuple is unnecessary. For comparison of versions, sort the Version instances directly. If you have another use case requiring the tuple, please file a bug with the setuptools project describing that need.

我将包添加到 buildout.cnfg

eggs =
Plone
Pillow
collective.addthis

Plone 和 Pillow 构建良好，但我尝试的每个附加组件都会出现相同的错误。

https://community.plone.org/上已经报告了很多类似的问题

问题很可能是从 pypi.python.org 迁移到 pypi.org

您可以添加：

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

如果您使用的是允许的主机，则需要 2 个新主机，并且可以跳过 *.python.org：

allow-hosts =
    pypi.org
    files.pythonhosted.org

您也可以使用当前版本的 setuptools 和 zc.buildout

注意：对于 setuptools > 38.7.0 你需要固定

plone.recipe.zope2instance = 4.4.0

（见https://github.com/plone/plone.recipe.zope2instance/blob/4.4.0/CHANGES.rst）
