Mac 上的 Python pip 安装无法运行

Question

我有一台 Macbook Air，想要安装 pip。我有更新的Python版本。我按照所有说明进行操作，但无法安装任何软件包。

我已经研究了1个多小时，看了很多文章和问题，但我无法弄清楚。

这是当我尝试安装 pip，然后安装一个名为 beautifulsoup 的包时，终端上显示的内容：

arnau@MacBook-Air-de-Arnau ~ % python --version
Python 2.7.16
arnau@MacBook-Air-de-Arnau ~ % curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

我不明白发生了什么或我应该做什么来解决该错误。

Answer 1

查看最后的警告，它说这些脚本不在 PATH 中。打开 Finder，将列出的文件复制到以下目录中：/usr/local/bin/

转到 /Users/arnau/Library/Python/2.7/bin。将列出的文件复制到 /usr/local/bin/ 中，以便命令行可以识别您的命令 pip。

\n

如果您不想执行此操作（我不建议执行此操作），您现在可以简单地使用其他答案，即使用 ，python -m pip它将命令行定向到当前目录这些文件的 /Users/arnau/Library/Python/2.7/bin。然而，您将来可能会遇到问题，所以我建议了上面的答案。

我还希望您\xe2\x80\x99 不会在每次必须安装软件包时额外键入 2 个关键字。

\n

Answer 2

尝试下面

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py
