在linux环境中调用科大讯飞SDK，与ROS 相结合实现语音控制.APPID对应的就是我申请的SDK包
catkin_make没有出现任何错误，但是在进行语音识别时却出现了用户校验失败错误：

libmsc.so文件用的就是我下载的SDK包里的，也放进了路径里面，还是报错，该怎么解决呢？
/usr/lib
系统：Linux ubuntu16.04 环境：ros kinetic
研究了两天时间，发现是在复制libmsc.so文件时的路径错误
指令如下：
sudo cp libmsc.o /usr/local/lib
少写了一个字母
sudo cp libmsc.so /usr/local/lib
