我们最近得到了一台新的 Linux 机器，它从我们当前的 plone 安装所在的旧机器上重新映像。我正在尝试在新机器上运行 buildout，但我在我们的 plonetheme src 产品上收到了这个 AssertionError。

We have the distribution that satisfies 'buildout.dumppickedversions==0.5'.

我们产品的init .py 脚本包含以下内容：

# See http://peak.telecommunity.com/DevCenter/setuptools#namespace-packages
try:
    __import__('pkg_resources').declare_namespace(__name__)
except ImportError:
    from pkgutil import extend_path
    __path__ = extend_path(__path__, __name__)

我在这里看到了类似的错误报告，但提供的答案不适用于我们的案例。我们在 src 中有其他产品，但这是唯一引起问题的产品。

有人可以帮我们解决这个错误吗？

检查setup.py主题包中的文件。你可能会发现：

# The next two lines may be deleted after you no longer need
# addcontent support from paster and before you distribute
# your package.
setup_requires=["PasteScript"],
paster_plugins = ["ZopeSkel"],

删除这些行。它们包含在为您的包生成的模板中，以便您可以使用 Zopeskel 本地命令添加新功能。开发后就不需要它了，而且它往往是以后问题的根源。

如评论中所述，替代解决方案是确保您在本地构建缓存中拥有正确的鸡蛋。但是，为什么旧​​的开发包会出现在实时站点上呢？
