使用PyInstaller将PyQt脚本编译为.exe时出现“ ModuleNotFound”

Question

我已经使用PyQt5 for GUI创建了finder.py脚本。

我已经在Windows上使用PyInstaller将脚本编译为.exe，并在virtualenv中运行以下命令：

pyinstaller finder.py

但是，当我尝试打开finder.exe时（无论是从virtualenv内部还是从外部），我都会得到

  

ModuleNotFoundError：没有名为“ PyQt5”的模块

根据其他SO答案，我尝试在创建可执行文件时将-c，-F，--windowed，--onefile的组合作为参数传递，但是没有用。

我该如何解决？
