Could not source the setup file for ROS distro "melodic"

[scout208]

I configured my distro to melodic through the pop-up msg, and now I get a notification that says Could not source the setup file for ROS distro "melodic". Furthermore my #include "ros/ros.h" and #include "std_msgs/String.h" statements are showing errors.

emmmmm，我的问题也找到了。把ros.h设置成g++的CPLUS_INCLUDE_PATH就好了。然后就不会再有烦人的红色波浪线了。emmmm这样一个小问题真是让人揪心啊，不过解决了就好哈哈哈哈。

Hi @scout208 , were you able to fix that issue? I have the same.
I can manually make the connections to the include files of ROS and get rid of wave underlines. I can also use ROS and Catkin commands from command line. But I still have that error message, and can not use the functionality of the extension in VSCode.

@kirillSum No, I gave up on my end.
