在conda的bash环境下进行catkin_make后出现报错

原因:在bash环境下无法正法编译

于是用 conda  deactivate 来退出bash环境

重新创建workspace后编译正常

永久解决问题方法:

使用的是anaconda的Python环境,用conda list 看看你有没有安装 empy,没有装的话就要在conda里面安装它,conda install -c conda-forge empy

还有个方法就是不用anaconda的Python环境,把.bashrc里面的 export PATH="/home/用户名/anaconda3/bin:$PATH" 注释掉,再source一下
