当我catkin_make时，我得到这个错误。

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
autorally_gazebo: Cannot locate rosdep definition for [effort_controllers]

我在 rosdep 安装时也遇到此错误。

我设法通过遵循卸载 em 并安装 empy 的旧解决方案解决了这个问题。但这还不够，因为 11 月 30 日的最新版本 empy (4.0) 似乎导致了这个新问题，所以我安装了一个旧版本，如下所示：

pip uninstall em
pip install empy==3.3.4
