使用pip install
了显然与蟒蛇2.7.11+我的Ubuntu 16.04系统中的任何模块抛出这个错误:
TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'
点子有什么问题?如有必要,如何重新安装?
更新:下面是完整的追溯

pip
通常将使用嵌入式requests
程序包,并且requests
通常将使用嵌入式urllib3
程序包。这些轮子不是嵌入式版本,可能与pip
某些代码的子类不兼容。移动/usr/share/python-wheels
一边吧?
pip
使用pip/_vendor/requests/
和pip/_vendor/requests/packages/urllib3/
,而不是/usr/share/python-wheels/requests-2.9.1-py2.py3-none-any.whl/requests
或/usr/share/python-wheels/urllib3-1.13.1-py2.py3-none-any.whl/urllib3
。
requests
并pip
嵌入它们的依赖关系。您的追溯显示未使用任何嵌入式版本,但是我不知道为什么这样做。
