解决Python出现_warn_unsafe_extraction问题的方法
在Python项目中运行出现了“AttributeError: ResourceManager instance has no attribute ‘_warn_unsafe_extraction'”问题,研究了一下,发现是setuptools在MacOS下的一个问题(见下图),我出现问题的是pymongo的库,需要删除pymongo,然后降级setuptools再重新安装。
解决方法:
1、删除pymongo:
sudo easy_install -mxN pmongo
2、降级setuptools:
sudo easy_install -mxN setuptools sudo easy_install "setuptools<0.7"
3、重装pymongo:
sudo easy_install pymongo
问题解决!!!!!
