这里有新鲜出炉的Python入门,程序狗速度看过来!

Python编程语言

Python 是一种面向对象、解释型计算机程序设计语言,由Guido van Rossum于1989年底发明,第一个公开发行版发行于1991年。Python语法简洁而清晰,具有丰富和强大的类库。它常被昵称为胶水语言,它能够把用其他语言制作的各种模块(尤其是C/C++)很轻松地联结在一起。


这篇文章主要为大家详细介绍了解决Python出现'_warn_unsafe_extraction'问题的方法,感兴趣的小伙伴们可以参考一下

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!!!!!
