week3/Callback-Topic-Message-Service-Action-new.txt/line 186 roslaunch ros_hello_again ros_hello123.launch 出現error 螢幕報錯 RLException: Unable to launch [CYCUICE_Hello-1]. If it is a script, you may be missing a '#!' declaration at the top. The traceback for the exception was written to the log file 網路搜尋結果 https://blog.csdn.net/x3613389/article/details/115740527 解决: 可能是launch内部格式、参数不对 例如,使用node方法 启动 其他launch文件,正确应该用include方法 启动其他launch文件

以解決 詳見 #2 Callback-Topic-Message-Service-Action-new.txt/line 186

當出現 Error提示為 : ros /usr/bin/env: ‘python \r’: no such file or directory

原因:DOS系統下和Linux系統下對於換行健的表示不同

解決辦法:

sudo apt-get install dos2unix dos2unix

P.S. 必須cd至該檔案的資料夾下

week3 Callback-Topic-Message-Service-Action-new --line.473 catkin_make 無法編譯 image fatal error: talker_listener_msg/PersonInfo.h: No such file or directory 1.無法理解.cpp裡include的 talker_listener_msg/ 在哪裡,註解中標的地方沒找到。 2.找得到PersonInfo.h但不知道怎麼修改程式碼

image

以解決:詳見 #2 Callback-Topic-Message-Service-Action-new --line.473
