Python测试在cmd上传递，在VS2012上失败

我在新机器（Windows 10）上设置Python（CPython 3.4,64位）。我安装numpy的&鼻子，跑通过翻译提示numpy.test（），以确保一切都按预期工作：Python测试在cmd上传递，在VS2012上失败

Running unit tests for numpy

nose version 1.3.4

OK (KNOWNFAIL=10, SKIP=20)

到目前为止好，但是当我通过PTVS在VS2012（做同样的事情我团队使用TFS源控制），有错误以及测试失败（如下图）：

我跑，我在VS通过命令行写剧本，结果是一样的，通过运行测试直接解释器，所以我相信在我的VS/Python设置中有些问题而不是脚本本身。问题是什么？

你的设置没有任何不妥之处。这就是说，numpy测试似乎是脆弱的，因为它们不允许调试器。我不确定那里发生了什么，但似乎涉及sys.getrefcount的测试以及依赖它的语义是特定的（通常只是对数组进行单个引用）是失败的。 >开始不调试 -

import sys 
def trace_func(f, e, a): 
    return trace_func 
sys.settrace(trace_func) 

import numpy 
numpy.test()

请注意，您可以运行VS脚本，而不通过调试调试它：

与sys.settrace注册您自己的跟踪功能，直接运行解释时，如你可以摄制此。这会给你的结果直接运行解释器。
