解决方案

UPDATED - Homebrew version after 1.5

根据官方 Homebrew 页面:

<块引用>

在 2018 年 3 月 1 日，python 公式将升级到 Python 3.x，并且将添加一个 python@2 公式以安装 Python 2.7(尽管这将仅用于桶，因此 python 和 python2 都不会添加到 PATH默认情况下没有手动 brew 链接 --force).我们将维护 python2、python3 和 python@3 别名.

因此要安装 Python 3，请运行以下命令:

brew install python3

然后，pip或pip3会自动安装，你可以通过pip install 安装任何包.>

较旧版本的 Homebrew

不仅brew install python3，还有brew postinstall python3

所以你必须运行:

brew install python3酿造后安装python3

请注意，您应该检查控制台，因为它可能会给您带来错误，在这种情况下，pip3 未 安装.

I'm trying to install pip3, but I'm not having any luck. Also, I tried sudo install and it did not work. How could I install pip3 on my Mac?

sudo easy_install pip3
Password:
Searching for pip3
Reading https://pypi.python.org/simple/pip3/
Couldn't find index page for 'pip3' (maybe misspelled?)
Scanning index of all packages (this may take a while)

No local packages or download links found for pip3
error: Could not find suitable distribution for Requirement.parse('pip3')

解决方案

UPDATED - Homebrew version after 1.5

According to the official Homebrew page:

On 1st March 2018 the python formula will be upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7 (although this will be keg-only so neither python nor python2 will be added to the PATH by default without a manual brew link --force). We will maintain python2, python3 and python@3 aliases.

So to install Python 3, run the following command:

brew install python3

Then, the pip or pip3 is installed automatically, and you can install any package by pip install <package>.

---

The older version of Homebrew

Not only brew install python3 but also brew postinstall python3

So you must run:

brew install python3
brew postinstall python3

Note that you should check the console, as it might get you errors and in that case, the pip3 is not installed.
