python tox; “哪个”全局站点软件包目录？

问题描述

我正在尝试使用tox的sitepackages=true标志。

（我已经用下面的xxx代替了真正的内部软件包名称）

我尝试从源代码手动安装一个不在pip中的软件包，该软件包出现在我的27个站点软件包中：

ls /Users/tc677g/.pyenv/versions/2.7.17/lib/python2.7/site-packages | grep xxx             
drwxr-xr-x    - root   17 Aug  8:17 xxx-1.0.0-py2.7.egg-info

此外，当我点冻结时，我会看到它：

pip freeze | grep xxx                                                                       
DEPRECATION: Python 2.7 will reach the end of its life on January 1st,2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip,can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
xxx==1.0.0

此外，我似乎可以将其导入python中：

   python                                                                                   
   >>> import xxx
   >>> 

但是，当我尝试在该项目上运行单元测试时，我得到：

tox                                                                                     461ms  Mon Aug 17 12:30:57 2020

这使我认为，启用sitepackages=true时，它将尝试从“不同的”全局软件包目录中读取。如何确认/调试/修复此问题？
