我正在尝试使用/opt/moose/miniconda/bin/python环境（由我的工作设置的环境）来处理一些单独的代码，并且在尝试使用鼻子模块运行测试时遇到错误。
要回到我的问题开始的地方，我在运行时收到此错误：
pip install nose
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/opt/moose/miniconda/lib/python2.7/site-packages/nose'
Consider using the `--user` option or check the permissions.
然后我跑了
pip install nose --user
The scripts nosetests and nosetests-2.7 are installed in '~/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
然后我将其添加到〜/ .bashrc文件中
export PATH=$PATH:~/.local/bin
现在，当我在主目录中打开python解释器时，我可以成功运行：
Python 2.7.15 |Anaconda, Inc.| (default, Dec 14 2018, 13:10:39)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import nose
>>> nose.main()
----------------------------------------------------------------------
Ran 0 tests in 0.002s
OK
但是，当我移至要在其中实际运行测试的目录时，我得到：
$ cd Documents/projects/neml
$ python
Python 2.7.15 |Anaconda, Inc.| (default, Dec 14 2018, 13:10:39)

>>> import nose
>>> nose.main()
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6
任何想法我为什么会收到此错误，似乎我在两个目录中都运行相同的python。这似乎是一个环境问题，但如果不是，请指出正确的方向。谢谢。
