【报错】QtCreator中导入ROS项目报错

解决

环境搭建好之后，在QtCreator中导入项目或执行cmake报错：

CMake Error at /opt/ros/melodic/share/catkin/cmake/safe_execute_process.cmake:11 (message):
  execute_process(/usr/bin/python2
  "/home/wheeltec_client/catkin_qt/build/catkin_generated/generate_cached_setup.py")
  returned error code 1
Call Stack (most recent call first):
  /opt/ros/melodic/share/catkin/cmake/all.cmake:208 (safe_execute_process)
  /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:20 (include)
  CMakeLists.txt:58 (find_package)

1.确保在系统环境变量中有QT的目录

打开~/.bashrc，加入目录，以下为我的路径：

export QT_HOME=/home/wheeltec_client/Qt5.12.9/Tools/QtCreator/bin

然后source一下

source ~/.bashrc

2.在Qt中加入ROS的环境

看下面的文章：
Qt导入CMake出现execute_process(/usr/bin/python2 "；…

重新Cmake一下
