python - 如何在没有 pip 的情况下升级/安装软件包

问题描述

我的环境中有 pip2 和 pip3。

这是我尝试安装（尝试安装 geopy: pip2 install geopy）或使用 pip2 升级任何软件包时得到的：

完整的日志在这里（对不起要点）。

我无法升级 pip2（出现与上述相同的错误）。我也无法卸载 pip2，因为 pip2 uninstall pip 返回

不在 OS 拥有的 /usr/lib/python2.7/dist-packages 上卸载 pip

从源代码 ( ) 安装包python setup.py install也不起作用：

geopy setup 命令中的错误：“extras_require”必须是一个字典，其值是包含有效项目/版本要求说明符的字符串或字符串列表。

我认为这是因为未满足 setuptools 的版本（并且我无法通过 pip 升级它，如上所述）。请建议我摆脱这种混乱的方法。

解决方案

尝试从https://pypi.org/project/geopy/geopy下载包 并运行

python setup.py install
