nvcc not found, despite being on path

I just installed CUDA 8.0 on macOS using the nvidia installer. It was installed at /Developer/NVIDIA.. and as such I prepended my PATH with export PATH=/Developer/NVIDIA/CUDA-8.0.61/bin${PATH:+:${PATH}}.

For some reason, it can't find nvcc (or the other binaries for that matter), despite the path being set and permissions seemingly okay.

~$ echo $PATH /Developer/NVIDIA/CUDA8.0.61/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/share/dotnet:/Library/TeX/texbin ~$ nvcc -bash: nvcc: command not found

Any ideas why this would be the case?

I had this same issue on windows after I did a custom installation and only selected the "runtime". May be a total coincidence/bad-install but when I re-installed it with these options selected, it worked. It should update your PATH automatically with CUDA_PATH variable

Because this is not the correct path:

/Developer/NVIDIA/CUDA8.0.61/bin

As indicated in the install guide, the correct path is:

/Developer/NVIDIA/CUDA-8.0.61/bin
                      ^

Note the dash at the indicated location.
