Homebrew vim 和 Numpy 不再支持选项了？答案

【问题描述】：

我通过brew install numpy --with-python3 安装了我的 Numpy，它运行良好。但是现在，我试图用brew upgrade numpy升级它，然后它迫使我安装python@2。

当我执行brew info numpy 时，我得到python@2 现在是必需的。这有什么问题吗？为什么python@2 会成为必需选项，而现在根本没有其他选项。

> brew info numpy

==> 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@987654328@ 做了同样的检查，我很确定我安装了brew install vim --with-python，然后它没有为我安装Lua。但是现在，Lua 也是必需的，所有选项都没有了。知道我的啤酒发生了什么吗？

您可以在此处阅读从 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。

用户现在需要在个人水龙头 (https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap) 中维护公式，因此请搜索旧的有效公式并使用它。
