Python出现'_warn_unsafe_extraction'解决方法

电脑技巧 python February 20 2014


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。

warn_unsafe_extraction

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!!!!!
