Python3 was working successfully but without pip3. Tried many advises from stackoverflow, quora and others. (numerous installs and uninstalls)
Python3 运行成功，但没有 pip3。尝试了来自 stackoverflow、quora 和其他人的许多建议。（无数次安装和卸载）
Python3 was always fine but without pip3. Finally I downloaded Python3 from: https://www.python.org/downloads/

UPDATED - Homebrew version after 1.5
更新 - 1.5 之后的 Homebrew 版本
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.
2018 年 3 月 1 日，python 公式将升级到 Python 3.x，并且将添加 python@2 公式以安装 Python 2.7（尽管这将仅用于桶，因此默认情况下 python 和 python2 都不会添加到 PATH 中手动 brew 链接 --force）。我们将维护 python2、python3 和 python@3 别名。
So to install Python 3, run the following command:
因此，要安装 Python 3，请运行以下命令：
brew install python3
Then, the pipor pip3is installed automatically, and you can install any package by pip install <package>.
然后，pip或pip3将自动安装，您可以通过pip install <package>.
The older version of Homebrew
旧版本的 Homebrew
Not only brew install python3but also brew postinstall python3
不仅brew install python3而且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 pip3is NOT installed.
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，未pip3安装。

It has to do with homebrew does not have permission to /usr/local
它与自制软件没有权限有关 /usr/local
Create the directory if not exist
如果目录不存在则创建
sudo mkdir lib
sudo mkdir Frameworks
Give the permissions inside /usr/localto homebrew so it can access them:
将内部权限授予/usr/localhomebrew，以便它可以访问它们：
sudo chown -R $(whoami) $(brew --prefix)/*
Now ostinstall python3
现在 ostinstall python3
brew postinstall python3
This will give you a successful installation
这将使您安装成功

After upgrading to Mac OS Catalina, and upgrading all my vEnv modules, pip3 stopped working (gave error: "TypeError: 'module' object is not callable").
升级到 Mac OS Catalina 并升级我所有的 vEnv 模块后，pip3 停止工作（给出错误：“TypeError: 'module' object is not callable”）。
Found question 58386953which led to here and solution.
发现问题58386953导致这里和解决方案。
- Exit from vEnv (I started fresh shell)
sudo python3 -m pip uninstall pip(this is necessary, but did not fix problem, because it removed the base Python pip, but didn't touch my vEnv pip)sudo easy_install pip(reinstalling pip in base Python, not in vEnv)- cd to your
vEnv/binand type "source activate" to get into vEnv rm pip pip3 pip3.6(seems to be the only way to get rid of the bogus pip's in vEnv)- Now pip is gone from vEnv, and we can use the one in the base Python (I wasn't able to successfully install pip into vEnv after deleting)
- 从 vEnv 退出（我开始了新的 shell）
sudo python3 -m pip uninstall pip（这是必要的，但没有解决问题，因为它删除了基本的 Python pip，但没有触及我的 vEnv pip）sudo easy_install pip（在基本 Python 中重新安装 pip，而不是在 vEnv 中）- cd到你的
vEnv/bin并输入“source activate”进入vEnv rm pip pip3 pip3.6（似乎是摆脱 vEnv 中虚假 pip 的唯一方法）- 现在 pip 从 vEnv 中消失了，我们可以使用基础 Python 中的那个（删除后我无法将 pip 成功安装到 vEnv 中）
