pip - 可移植 python - 无法安装 pip

Question

我正在尝试在我的 USB 驱动器上获取 pip。按照 this web sit 上的说明进行操作, 我下载了 get-pip.py并运行 python get-pip.py ( python 在环境路径中)。不幸的是脚本通过一个错误。我已将日志文件上传到 here .错误本身是:

Exception:
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

任何人都可以向我解释我做错了什么吗？

我使用的是可移植 python 3.2.5.1，从安装开始直到我尝试安装 pip 时它都是全新的。

Answer 1

我在使用相同版本的 Portable Python 3.2.5.1 时遇到了同样的问题。由于脚本内部的一些语法错误，位于 App\Scripts\easy_install.py 中的 easy_install.py 脚本对我来说也被破坏了。

经过无数个死胡同，我找到了https://winpython.github.io/ .它从可移植 Python 停止的地方开始。
