ERROR: unable to process source [https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml]: <urlopen error [Errno 111] Connection refused> other link

你可以尝试使用以下链接来解决这个问题：

- https://raw.githubusercontent.com/ros/homebrew-rosdep/master/rosdep-10.12-homebrew.yaml
- https://raw.githubusercontent.com/ros/homebrew-rosdep/master/rosdep-10.13-homebrew.yaml
- https://raw.githubusercontent.com/ros/homebrew-rosdep/master/rosdep-10.14-homebrew.yaml

根据你的 macOS 版本选择对应的链接，然后将这个链接添加到你的 rosdep 源中。例如，如果你的 macOS 版本是 10.13 High Sierra，你可以使用以下命令将第二个链接添加到你的 rosdep 源中：

sudo rosdep init
rosdep update
sudo rosdep add-source https://raw.githubusercontent.com/ros/homebrew-rosdep/master/rosdep-10.13-homebrew.yaml

这样，你就可以通过 rosdep 来安装 ROS 所需的依赖了。
