Problems about building an executable using py2exe

I tried to build an executable following steps in https://www.psychopy.org/recipes/appFromScript.html, but failed in the first step when I tried to install py2exe, the fault is as follows


I think it did not find the path of the standalone version of psychopy, then how can I deal with it? I am uising [StandalonePsychoPy3-3.2.4-win32.exe]
