Installing OpenCV in Jetson NANO always get Error

I used the guide: https://github.com/AastaNV/JEP/blob/master/script/install_opencv4.0.0_Nano.sh
but when I build it always get [99%] sometimes [100%]. But It always fails :(( . Anybody help me

  • It loses my day :(, Does anyone have experience in this Case?
  • Do I need to setup/ install other libs first?
