问题是当我检查/打印sys路径时，我在virtualenv中得到以下内容：
/Users/myuser/ais/bin
/Users/myuser/ais/lib/python27.zip
/Users/myuser/ais/lib/python2.7
/Users/myuser/ais/lib/python2.7/plat-darwin
/Users/myuser/ais/lib/python2.7/plat-mac
/Users/myuser/ais/lib/python2.7/plat-mac/lib-scriptpackages
/Users/myuser/ais/Extras/lib/python
/Users/myuser/ais/lib/python2.7/lib-tk
/Users/myuser/ais/lib/python2.7/lib-old
/Users/myuser/ais/lib/python2.7/lib-dynload
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/Users/myuser/ais/lib/python2.7/site-packages
我已经尝试了
which python
which pip
在虚拟环境中，它看起来很好。
我也试过
unset $PYTHONPATH
没有效果。
任何建议我如何解决这个问题？我希望virtualenv完全独立于我的全局设置和包。
提前多多感谢。 最好 SC
