dayna@dayna-virtual-machine:~/catkin_pih$ rosrun wrs_run pick_place_simu
[rosrun] Couldn't find executable named pick_place_simu below /home/dayna/catkin_pih/src/wrs-master/wrs/wrs_simu/wrs_run
根据网上的提示我把pick_place_simu的cpp文件属性设置为可以访问了，运行语句还是报错。

@小鱼 这个从哪改或者从哪找呢

@小鱼 好吧，确实是错了

升级了源，用的是Ubuntu18.04，对应melodic，都没错，就是安装不上roscpy，求解答！
