Install Psychopy3 into Vizard7

[Roy]

Does anyone know how to install and use psychopy3 in vizard7?
When I tried to install it from vizard's package manager, I got error as below,


error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\VC\\Tools\\MSVC\\14.28.2 9333\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly.


This error is involved in cryptography, how to fix?

Thanks
