Seems you only have the C++ executables that get built in this project.

Did you install this from source or via apt-get?

If from source, double check if the python scripts in mavros/scripts/ are actually executable...

EDIT

@YingHua you then probably lost the file permissions due to a USB Drive which was formatted with a filesystem that does not support file permissions (e.g. NTFS or FAT, if I'm not mistaken). If you want to transfer data from one PC to another via USB, best use an EXT formatted dive to avoid this problem.

Also: please answer @mig's question: how did you install the mavros files? scripts/mavsys should have executable permissions already set, a git clone or installation through apt-get should not change that.

@gvdboorn :OK,Thanks for reminding me!

Dear @mig : there is some problem with my platform internet so that I download source code form github and move that to platform with usb.

@YingHua Thanks a lot! That solved my problem too. But, the first time I executed, I don't remember doing this. why are the permissions lost?
