Plone 4.3 AssertionError运行Buildout

标签: plone buildout plone-4.x

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成像。我正在尝试在新机器上运行buildout但是我在我们的plonetheme src产品上得到了这个AssertionError。

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

An internal error occurred due to a bug in either zc.buildout or in a

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__)

我发现类似的错误报告here,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,但这是唯一导致问题的产品。

有人可以帮我们解决这个错误吗?

1 个答案:

答案 0 :(得分:3)

检查主题包中的setup.py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。它们包含在包的生成模板中,以便您可以使用Zopeskel本地命令添加新功能。开发后你不需要它,以后它常常是问题的根源。

备注解决方案中提到的另一种解决方案是确保在本地构建缓存中使用正确的鸡蛋。但为什么旧的开发包围绕着一个现场?
