Issue with installing QuTip on Windows

[ravikish...@gmail.com]

Hello, 

I am installing QuTip on Windows, and get an error as shown below, until this point everything seemed ok :

cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -Iqutip/cy "-Id:\program files\python\python36\lib\site-packages\numpy\core\include" "-Id:\program files\python\python36\lib\site-packages\numpy\core\include" "-Id:\program files\python\python36\include" "-Id:\program files\python\python36\include" /EHsc /Tpqutip/cy/spmatfuncs.cpp /Fobuild\temp.win-amd64-3.6\Release\qutip/cy/spmatfuncs.obj /w /Ox

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

How can I fix it ?
