pip3 未透過 Homebrew (macOS) 安裝最新的 python3

pip3在最新的 Homebrewpython3更新後消失了。

user:~$ python3 --version
Python 3.7.3
user:~$ pip3 --version
-bash: pip3: command not found

Homebrew 聲稱它安裝了符號鏈接，pip3但它們不存在：

user:~$ brew info python
python: stable 3.7.3 (bottled), HEAD
Interpreted, interactive, object-oriented programming language
https://www.python.org/
/usr/local/Cellar/python/3.7.3 (8,115 files, 114.3MB) *
  Built from source on 2019-04-02 at 15:12:30
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/python.rb
==> Dependencies
Build: pkg-config ✔
Required: gdbm ✔, openssl ✔, readline ✔, sqlite ✔, xz ✔
==> Options
--HEAD
    Install HEAD version
==> Caveats
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

brew cleanup並且brew reinstall python不工作。我也在使用pyenv，我想知道這是否會產生任何問題。現在我已經卸載了所有python版本pyenv並重新安裝了最新的 Homewbrew，仍然沒有成功。

PS 我知道python3 -m pip命令，但正在尋找一種恢復標準pip3呼叫的方法。
