libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/aarch64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) 

libGL error: failed to load driver: swrast 

不能加载swrast ，上网查后，我安装了sudo apt-get install libgl1-mesa-glx，还有加入环境变量export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/dri:$LD_LIBRARY_PATH,仍未能解决。
