我正在用Python编写一个包。我使用virtualenv。我在virtualenv的.pth路径中设置了模块的根路径，这样我就可以在开发代码和测试时导入包的模块(问题1:这是一种好方法吗?)这很好(这是一个例子，这是我想要的行为):
(VEnvTestRc) zz@zz:~/Desktop/GitFolders/rc$ python
Python 2.7.12 (default, Jul 1 2016, 15:12:24)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from rc import ns
>>> exit()
(VEnvTestRc) zz@zz:~/Desktop/GitFolders/rc$ python tests/test_ns.py
issued command: echo hello
command output: hello
但是，如果我尝试使用PyTest，我会得到一些导入错误消息:
(VEnvTestRc) zz@zz:~/Desktop/GitFolders/rc$ pytest

我有点困惑，这似乎表明一个导入错误，但Python做得很好，为什么有一个问题，特别是与PyTest?对原因/补救(问题2)有什么建议吗?我在谷歌上搜索了PyTest的“ImportError: cannot import”错误，但我得到的点击率与丢失的python路径和补救措施有关，这似乎不是这里的问题。有什么建议吗?
