我尝试安装时出现错误链选择在文件夹中的Python 自己的pip脚本上Python34。不知为何它无法安装。

pip install不知为何被打破了[.]

这似乎不太可能。

pip我在 Python 2.7.16 和 Python 3.x 中使用相对较新的版本（分别为pip版本 18.x 和版本 19.x）时都遇到了相同的错误pip。pip除此之外，对我来说一切正常。

更有可能的是，这opts是一个旧模块，并且在其脚本中使用了过时的参考和说明，从而导致了错误。

关于年龄，请考虑opts 于 2010 年发布，以及 Python 2.7目前Python 2.7 的官方支持将于 2020 年 1 月结束。

建议，如果这不仅仅是现有脚本的支持模块，你应该考虑使用除 之外的其他东西opts。一种选择可能是 Python 自己的参数解析图书馆。
