If I try to compile a C++ extension (both JIT and setup.py variants) the first line of output is
which: no nvcc in ($PATH)

where $PATH is my actual path.
Since I installed the CPU optimized version without CUDA on my machine, I wonder whether this hints at either a problem in my installation or a bug.
My version is ‘1.3.1+cpu’, but the same occurs also for the nightly build. My python version is 3.7 and I installed with pip in a virtual environment.
