OSError：[WinError 193]％1不是有效的Win32应用程序opencv.js

我试图opencv.js从他们页面上的教程中构建。

除了最后一个步骤，我已经完成了所有步骤：

C:\Users\student>python C:\Users\student\opencv\platforms\js\build_js.py documents

这给了我这个错误：

Args: Namespace(build_dir='documents', build_doc=False, build_test=False, build_wasm=False, clean_build_dir=False, config_only=False, emscripten_dir=None, enable_exception=False, opencv_dir='C:\\Users\\student\\opencv', skip_config=False)
Cannot get Emscripten path, please specify it either by EMSCRIPTEN environment variable or --emscripten_dir option.

我尝试使用这个

C:\Users\student>python C:\Users\student\opencv\platforms\js\build_js.py --emscripten=C:\Users\student\emsdk\emscripten\1.37.36 documents

带有--emscripten选项，但我得到了这个：

Args: Namespace(build_dir='documents', build_doc=False, build_test=False, build_wasm=False, clean_build_dir=False, config_only=False, emscripten_dir='C:\\Users\\student\\emsdk\\emscripten\\1.37.36', enable_exception=False, opencv_dir='C:\\Users\\student\\opencv', skip_config=False)

我已经搜索了此问题近2天，但没有任何解决方案。

我正在使用Windows 10 64位。
