Python 导入错误：没有名为testrunner的模块

我随后将

zc.recipe.testrunner

添加到我的构建中。我可以成功运行buildout，但当我运行

bin/test

时，我得到：

ImportError: No module named testrunner

我有

zope.testrunner-4.0.4-py2.4.egg

in

/usr/local/lib/python2.4/site-packages

我也别住了

zope.testrunner = 4.0.4
zc.recipe.testruner = 1.4.0
zc.recipe.egg = 1.3.2

当我运行buildout时，我使用了

-vvv

，得到了：

...

为什么我会害怕？zope.testrunner是否未正确安装

编辑：

[buildout]
...
parts =
    ...
    test

[test]
recipe = zc.recipe.testrunner
defaults = ['--auto-color', '--auto-progress']
eggs = 
    my.product

Traceback (most recent call last):
File "/home/jil/mySandbox/myTrunk/bin/test", line 20, in ?
  import zope.testrunner

这是我的构建中的相关部分：

[buildout]

    ...

Traceback (most recent call last):

  import zope.testrunner
ImportError: No module named testrunner

这是

bin/test

中的内容：

[buildout]
...

Traceback (most recent call last):
File "/home/jil/mySandbox/myTrunk/bin/test", line 20, in ?
  import zope.testrunner
ImportError: No module named testrunner

这是运行

bin/test

后出现的错误：

    ...

[test]
recipe = zc.recipe.testrunner

我也有同样的问题。至少在我的例子中，原因是混合了“站点包”中已安装的依赖项和“鸡蛋”中由buildout安装的依赖项：zope.deprecation和zope.interface已经在我的“站点包”目录中，因此buildout没有重新安装。“bin/test”可执行文件上的路径操作似乎从“site packages”导入了“zope”包，而没有“testrunner”子包

---

尝试从“site packages”中删除所有zope.*包并重新运行buildout，或在buildout.cfg的“[buildout]”部分使用“include site packages=false”。第一个解决方案对我有效。

向我们展示构建的测试部分的配置，以及生成的bin/test脚本的内容。并且，可能是生成的bin/test脚本的完整回溯无效。可能testrunner只与Python2.6+Plone 4兼容？@Mikkoohtama我使用的是Plone3/Python2.4。它说zc.recipe.testrunner与Plone 4、Plone 3和Plone 2.5.x兼容。此外，zc.recipe.testrunner依赖于zope.testrunner（它依赖于zope.interface和zope.exceptions）。永远不要提及删除Python2.4支持。在任何情况下，您的bin/test脚本的sys.path中都没有任何鸡蛋，因此它可能无法工作。这个答案很有帮助，谢谢。不需要

包含站点包

，只需要创建一个新的virtualenv并只在其中安装buildout，就行了。
