我怀疑我没有正确安装鼻子测试。我使用了 easy_install nose - 输出是

Searching for nose
Best match: nose 1.0.0
Processing nose-1.0.0-py2.7.egg
nose 1.0.0 is already the active version in easy-install.pth
Installing nosetests-script.py script to C:\Python27\Scripts
Installing nosetests.exe script to C:\Python27\Scripts
Installing nosetests-2.7-script.py script to C:\Python27\Script
Installing nosetests-2.7.exe script to C:\Python27\Scripts

所以看起来它安装得很好。但是当我运行nosetests -h

PS C:\Users\john\code\python> nosetests -h
Traceback (most recent call last):
  File "C:\Python27\Scripts\nosetests-script.py", line 9, in <module>
    load_entry_point('nose==1.0.0', 'console_scripts', 'nosetests')()
  File "C:\Python27\lib\site-packages\nose-1.0.0-py2.7.egg\nose\core.py", line 118, in __init__
    **extra_args)
TypeError: __init__() got an unexpected keyword argument 'exit'

我是否以某种方式错过了设置步骤？

诡异的。在构造函数nose/core.py中TestProgram调用父构造函数，如下所示：

...
extra_args = {}
version = sys.version_info[0:2]
if version >= (2,7) and version != (3,0):
    extra_args['exit'] = exit
unittest.TestProgram.__init__(
    self, module=module, defaultTest=defaultTest,
    argv=argv, testRunner=testRunner, testLoader=testLoader,
    **extra_args)

TestProgramin的构造函数unittest/main.py接受exit参数：

class TestProgram(object):
    ...
    def __init__(self, module='__main__', defaultTest=None, argv=None,
                    testRunner=None, testLoader=loader.defaultTestLoader,
                    exit=True, verbosity=1, failfast=None, catchbreak=None,
                    buffer=None):
        ...

所以......我不知道这个错误是怎么发生的。您是否安装了更多版本的 Python？你的鼻子测试真的使用了unittestPython 2.7 的正确模块吗？你能看看unittest\main.py（在你的某处C:\Python27）并检查TestProgram构造函数，它是否有exit参数？
