自制的vim和Numpy不再支持选项了？

Question

我通过brew install numpy --with-python3安装了我的Numpy，它运行得很好。但是现在，我试图用brew upgrade numpy升级它，然后它强迫我安装python@2。在

当我做brew info numpy时，我得到现在需要python@2。这有什么问题吗？为什么python@2成为必需选项，而现在根本没有其他选项。在

> brew info numpy
numpy: stable 1.15.4 (bottled), HEAD
Package for scientific computing with Python

==> Options
--HEAD
    Install HEAD version
==> Caveats
If you use system python (that comes - depending on the OS X version -
with older versions of numpy, scipy and matplotlib), you may need to
ensure that the brewed packages come earlier in Python's sys.path with:
  mkdir -p     /Users/cheng/Library/Python/2.7/lib/python/site-packages
  echo 'import sys; sys.path.insert(1, "/usr/local/lib/python3.7/site-packages")' >> /Users/cheng/Library/Python/2.7/lib/python/site-packages/homebrew.pth

我对vim做了同样的检查，我确信我是用brew install vim --with-python安装的，然后它没有为我安装Lua。但是现在，Lua也是必需的，所有选项都不见了。知道我的啤酒怎么了吗？在

您可以在这里阅读从homebrew-core公式中删除所有选项的决定背后的依据：Remove all options from Homebrew/homebrew-core formulae #31510。在

用户现在需要在个人taps（https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap）中维护公式，所以搜索一个旧的工作公式并使用它。在
