python - Py.test 收集阶段需要很长时间

Question

一般来说，我对 Python 开发真的很陌生，更不用说用 pytest 进行测试了。我的问题是 pytest 收集阶段运行异常缓慢。我指定的测试目录只包含少量文件，其中只有一个文件包含三个测试。收集几乎需要整整一分钟，之后实际测试会在几秒钟内运行。我看过类似的问题，但找不到解决方案。我认为这并不重要(因为 py.test 即使从命令行也很慢)，但我使用的是 pycharm IDE。操作系统是 Ubuntu。

这可能是相关的:如果我在几秒钟后终止进程，我通常会以堆栈跟踪结束，如下所示:

<A FEW LINES OMITTED...>
File "/usr/local/lib/python2.7/dist-packages/_pytest/core.py", line 413, in __call__
    return self._docall(methods, kwargs)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/core.py", line 424, in _docall
    res = mc.execute()
  File "/usr/local/lib/python2.7/dist-packages/_pytest/core.py", line 315, in execute
    res = method(**kwargs)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/helpconfig.py", line 27, in pytest_cmdline_parse
    config = __multicall__.execute()
  File "/usr/local/lib/python2.7/dist-packages/_pytest/core.py", line 315, in execute
    res = method(**kwargs)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 636, in pytest_cmdline_parse
    self.parse(args)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 747, in parse
    self._preparse(args)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 709, in _preparse
    self._initini(args)
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 704, in _initini
    self.inicfg = getcfg(args, ["pytest.ini", "tox.ini", "setup.cfg"])
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 861, in getcfg
    if exists(p):
  File "/usr/local/lib/python2.7/dist-packages/_pytest/config.py", line 848, in exists
    return path.check()
  File "/usr/local/lib/python2.7/dist-packages/py/_path/local.py", line 352, in check
    return exists(self.strpath)
  File "/usr/lib/python2.7/genericpath.py", line 18, in exists
    os.stat(path)
KeyboardInterrupt

或者有时...

<STACK TRACE...>
  File "/usr/local/lib/python2.7/dist-packages/py/_iniconfig.py", line 50, in __init__
    f = open(self.path)
KeyboardInterrupt

也许 KeyboardInterrupt 之前的最后两个调用之一非常慢？

如果您需要，请询问更多详细信息!

干杯!

我有同样的问题。我的解决方法是设置 Working directory Run/Debug Configuration 中的设置到 manage.py 所在的文件夹位于。
