ubuntu16.04下安装的ros kinetic版本,之前roscore打开很正常,今天打开时报错,错误信息如下:
Invalid <param> tag: Cannot load command parameter [rosversion]: command [rosversion roslaunch] returned with code [1].
Param xml is <param command="rosversion roslaunch" name="rosversion"/>
The traceback for the exception was written to the log file
No handlers could be found for logger "roslaunch
先source了一下,并没有得到解决,后来回忆了一下,前一天修改了某个包里的package.xml文件,修改出了问题,把这个文件修正后解决了这个问题。
