ROS wiki 教程中 “make install -j8 -l8” failed

之前一直跟着ros wiki 做遇到了一個問題，在生成msg 和 srv 的部分，

按照之前的步驟，一步步往下做，到了編譯的部分，就會出先如下圖所示的錯誤

一直摸索了半天沒搞明白

最後在師兄的幫忙下，解決了

huang@huang-Lenovo-Gaming:~/catkin_ws$ rm -rf build devel

個人推測的原因應該是之前編譯的過程中的生成文件（之前的tutorial）與結果衝突，導致不能成功編譯，在網上找了很久也沒有找到相關的解決辦法，自己mark一下，如果有大佬看到知道原因，歡顏糾正（小白一枚）
