Unable to find vcvarsall.bat

Hello. I am trying to build cupy from source(for development) in Windows with CUDA and the following error shows up :

Even though I run "pip install -e ." after initialising Visual Studio 2017 x64 environment (using vcvarsall.bat), this error still persists. Can anyone tell me what is going on.

Some Cuda packages like cuTensor is not found, but it was optional and package can be build without cuTensor also. So the main issue is that Unable to find vcvarsall.bat (which clearly is running fine in the same command prompt). Also Since I want to develop, installing from wheel is out of question. Somebody help please !! Thank you
