我无法在macOS Sierra上安装自制软件.安装暂停

brew update
brew upgrade
brew tap ethereum/ethereum
brew install solidity

brew linkapps solidity

正如在solidity#binary-packages所建议的那样.但是当我尝试brew install solidity时,安装boost时安装过程就会卡在这里：

bash-3.2$brew install solidity

我确实找到了这个brew hanging thread,并试图修复brew医生给我的一切,我安装了最新的命令行工具.我无法让它工作.有任何想法吗？
