cl.exe installed but not found

问题

I've looked at the other questions on this, all say install visual studio with c++, I have done this - 2017 version. I'm trying to build pypoisson in python3 which requires the c++ complier, I get this error:

cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\Users\garyn\PycharmProjects\pointcloudprocessor\venv\lib\site-packages\numpy\core\include -IC:\Users\garyn\PycharmProjects\pointcloudprocessor\venv\include "-IC:\Pr

error: command 'cl.exe' failed: No such file or directory

I looked in my system variables and in path there is a route to cl.exe

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\bin\Hostx64\x64\cl.exe

and

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\bin

My system is 64-bit OS and x64-based processor

Searching windows for cl.exe returns 8 possibilities all under the directory: C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\bin some in Hostx64 and Hostx86

Any ideas? I've been stuck on this for months.
