本文主要是介绍Ubuntu20.04 [Ros Noetic]版本——在catkin_make编译时出现报错的解决方案，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

今天在新的笔记本电脑上进行catkin_make的编译过程中遇到了报错，这个报错在之前也遇到过，但是，我却忘了怎么解决。很是头痛！

经过多篇博客的查询，特此解决了这个编译报错的问题，于此特地记录！！！

其实，关键的报错点如下:

CMake Error at /opt/ros/noetic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

根据这个报错提示，我找到了几篇相关的博客：

根据上面这2篇博客其实就可以解决问题了
