我正在尝试使用Homebrew在High Sierra上安装cmake。无论我使用什么功能，它都会开始下载
public space使用
时也是一样internal space我绝对可以同时连接到Bintray和Github，所以它不是连接的问题。此外，我已经成功更改了某些目录的所有者。
brew install cmake

Do not file an issue on GitHub about this: you will need to
figure out for
yourself what issue with your internet connection restricts your
access to
both Bintray (used for Homebrew bottles/binary packages) and
GitHub
(used for Homebrew updates).
Error: Failed to install vendor Ruby.
我还注意到Bintray上没有brew doctor
brew cleanup
，但是我可以从Github下载它。有人可以帮忙吗？
