自制-python @ 3和python3有什么区别? [英] Homebrew - What's the difference between `python@3` and `python3`?

问题描述

我通过自制软件安装了python 2.7.14，我也想通过自制软件安装最新版本的python 3.当我搜索"python3"时，我看到以下结果.

I have python 2.7.14 installed via homebrew, and I'd like to install the latest version of python 3 via homebrew as well. When I search for "python3" I see the following results.

$ brew search python3
==> Formulae
boost-python3                      python3                            python@3

If you meant "python3" specifically:
It was migrated from homebrew/cask to homebrew/core.

为什么同时存在python@3和python3?有什么区别?

Why is there both python@3 and python3? What's the difference?

推荐答案

目前，homebrew-core中只有两个不同的Python公式:

Right now, there are only two distinct Formula for Python in homebrew-core: python, and python@2.

python@3和python3都是Formula/python.rb的别名.因此，它们只是安装相同软件包的不同名称.

python@3 and python3 are both aliases to Formula/python.rb. Thus, they're just different names that install the same package.

请参阅两个别名:

• Aliases/python@3
• Aliases/python3

...都指向:

• Formula/python.rb

要自行查找，请使用brew info(例如brew info python@3)，然后在From:行中找到所用公式的URL.例如，此行可能看起来像:

To find this yourself, use brew info -- for example, brew info python@3 -- and look for the From: line with a URL to the formula which was used. For example, this line might look like:

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/python.rb
