python - 如何正确地将“脚本轮”添加到 python 路径？

Question

我刚刚从python.org安装了 Python 3.7 。我按照这个StackOverflow 帖子将我的默认 Python 更改为 Python 3。从那里我运行了 Update Shell Profile.command 和 Install Certificates.command（Finder > Applications > Python 3.7）。

然后我发现我无法运行 pip 命令

> $ pip --version

> -bash: pip: command not found

随后我运行了以下2个命令..

> $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
> 
> $ python get-pip.py

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'
Consider using the `--user` option or check the permissions.

然后我添加了--user标志

> $ python get-pip.py --user

这是我不明白的

什么是轮子，如何将其添加到正确的路径？

> $ which python

> /usr/local/opt/python/libexec/bin/python
