Sorry for late reply. I do not know sage (and assuming Linux) but I would start with checking if nvcc is in PATH. When you install cuda toolkit with default settings (/usr/local/cuda) nvcc is not in PATH. I added /usr/local/cuda/bin to PATH in ~/.bashrc If you add nvcc to PATH in other file (like /etc/profile, ~/.bash_profile, etc.) it might not be added every time. Similarly, when you run program as another user, (s)he does not have nvcc in the PATH.
