在命令行中运行大多数 python 脚本时会收到以下类型的警告:
/Library/Python/2.6/site-packages/virtualenvwrapper/hook_loader.py:16: UserWarning: Module
pkg_resources was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.pyc, but /Library/Python/2.6/site-packages is being added to sys.path
import pkg_resources
/Library/Python/2.6/site-packages/virtualenvwrapper/hook_loader.py:16: UserWarning: Module site was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site.pyc, but /Library/Python/2.6/site-packages is being added to sys.path
import pkg_resources
我认为这与使用分布式和 virtualenv 的组合有关,但想检查是否有其他人遇到过这个问题或者知道如何修复它。
