CUDA 10.1 & VS2019 - Environment problem?

Accelerated Computing CUDA CUDA Setup and Installation
1

I have recently installed VS2019 & CUDA 10.1 and am trying to compile simple *.cu files at the command line however nvcc is reporting ‘nvcc fatal : Could not set up the environment for Microsoft Visual Studio’

The attempt to run nvcc gives me the error and a long path to vcvars64.bat. The error encapsulates the path with single quotes.

Trying to run the batch file with the single quote encapsulation results in a further error, however running the batch file from the same location using double quotes results in success. Further more running just the vcvars64.bat from the same location (relying on a the preconfigured environment) also works.

Below are the results I am getting:

Can anyone suggest why this is happening and what I am doing wrong.

Thanks in anticipation of your help.

Double-check the installation guide of CUDA for windows and make sure you are using supported versions of VS, driver, and set the environment variables as the guide says.
I don’t know what is in your system, but your description shows 2 versions of VS installed.

Update - Issued resolved by reinstalling in an account which does not include spaces within the account name. Come on Nvidia, your testing should pick this sort of thing up.

During installation, think I recall instructions about not having spaces in the path. Anyway, if you are admin on your workstation, you can put Visual Studio into location with simpler path. For example, instead of having to struggle with:

…Studio/2019/Community/VC/Tools/MSVC/14.20.27508/bin/HostX86/x64/…/…/…/…/…/…/…/VC/…

we can tell Visual Studio where to go, e.g.,

D:/VS/VC/…

Then all those vcvars*.bat files are easier to find(!)

D:/VS/VC/Auxiliary/Build/vcvars*.bat
