catkin\_make:build报错信息显示如下：

由于安装ROS时没有安装它的opencv模块，导致没有cv\_bridge库，输入命令安装即可：

sudo apt-get install ros-melodic-cv-bridge

然后会显示即将安装的软件列表，确认无误后输入y回车进行安装。

将会同时安装下列软件：
      liblept5 libopencv-calib3d-dev libopencv-contrib-dev libopencv-contrib3.2
      libopencv-dev libopencv-features2d-dev libopencv-highgui-dev
      libopencv-objdetect-dev libopencv-stitching-dev libopencv-videostab-dev
      libopencv3.2-java libopencv3.2-jni libtesseract4 python-opencv
    建议安装：
      opencv-doc
    下列【新】软件包将被安装：
      liblept5 libopencv-calib3d-dev libopencv-contrib-dev libopencv-contrib3.2
      libopencv-dev libopencv-features2d-dev libopencv-highgui-dev
      libopencv-objdetect-dev libopencv-stitching-dev libopencv-videostab-dev
      libopencv3.2-java libopencv3.2-jni libtesseract4 python-opencv
      ros-melodic-cv-bridge
    升级了 0 个软件包，新安装了 15 个软件包，要卸载 0 个软件包，有 417 个软件包未被升级。
    需要下载 8,128 kB 的归档。
    解压缩后会消耗 36.8 MB 的额外空间。
    您希望继续执行吗？ [Y/n] y

再次catkin\_make:build发现程序运行成功。
