构建找不到Plon的pip包

Question

我试图通过buildout向Plone添加附加组件，但它找不到包。我已经在virtualenv和系统范围的python中尝试过了

我跟踪了Plone网站上的设置 Setup instructions

我尝试的每个加载项都会出现以下错误

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.

在https://community.plone.org/上也有很多类似的问题

最可能的问题是从中的迁移pypi.python.org至pypi.org网站你知道吗

您可以添加：

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

如果您使用的是允许的主机，您需要2个新的，可以跳过*。python.org网站地址：

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

或者，您可以使用当前版本的setuptools和zc.buildout公司你知道吗

注意：对于setuptools>；38.7.0，您需要固定

plone.recipe.zope2instance = 4.4.0

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