如何在 USB 驱动器上便携式安装 pip？

Question

我正在尝试将 pip 安装在 USB 驱动器 F: 旁边的便携式 python 上，但它似乎无法正常工作。我使用 Git-bash (msys) 作为我的命令行。请参阅下面的我的尝试：

MYPC /f
$ which python
/f/ppython275/App/python    

MYPC /f
$ which pip    

MYPC /f
$ python get-pip.py

MYPC /f
$ which pip

我已经重新启动了命令行。但是“哪个点”仍然没有产生任何结果。我该如何解决这个问题？

Answer 1

您需要编辑您的 $PATH 环境变量以添加 /f/ppython275/App/Scripts，以便 shell 在该目录中查找可执行文件。

编辑您的 ~/.bashrc 或 ~/.bash_profile 并添加以下内容：

export PATH=$PATH:/f/ppython275/App/Scripts

保存，重新启动你的 shell，你应该已经准备好了。
