我正试图在这个guide之后在我的mac中安装ros kinetic。 （我已经安装并更新了自制软件）在本指南的第一步中，我运行命令行：
brew tap ros/deps
这让我回到了以下错误

这是我的brew --config

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
python@2
numpy

这个错误避免我在我的mac mojave中安装ross kinetic，请帮帮我。
https://github.com/ros/homebrew-deps
我将此存储库放入/ usr / local / Homebrew / Library / Taps / ros / homebrew-dep，然后在gfortran.rb中，将“MacOS.prefer_64_bit”修改为“MacOS.is_64_bit”。并再次运行“brew tap ros / deps”。
它适用于我的Mac。
