nosetests - nosetest Ran 0 对 pandas 的测试

Question

我尝试遵循熊猫文档。将其安装在 Ubuntu 10.4 上，但是当运行鼻子测试时得到结果 0 测试

~$ nosetests pandas

----------------------------------------------------------------------
Ran 0 tests in 0.002s

OK

似乎所有东西都安装正确，所以不知道如何处理它或如何解释（我是鼻子测试的新手）。你能帮我解释一下输出还是建议我应该如何运行这个测试

谢谢

在尝试此操作之前，我在每个尝试过的目录中都收到了ran 0 tests消息：

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pandas-0.11.0-py2.7-macosx-10.6-intel.egg/pandas/tests$ sudo nosetests *

sudo 是消除第一轮访问错误所必需的。然后我得到了这些错误：
