python - 如何在 USB 驱动器上可移植安装 pip？

Question

我正在尝试将 pip 安装在 USB 驱动器 F: 旁边的可移植 python 上，但它似乎不起作用。我使用 Git-bash (msys) 作为命令行。请参阅下面我的尝试:

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

MYPC /f
$ which pip    

MYPC /f
$ python get-pip.py

MYPC /f
$ which pip

我已重新启动命令行。但“哪个 pip ”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 $PATH 环境变量以添加 /f/ppython275/App/Scr​​ipts，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，重新启动您的 shell，然后就一切就绪了。
