Question

我尝试在其页面上PyGame构建opencv.js。

我已经完成了除最后一步之外的所有步骤来构建它：

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.

我尝试使用它然后

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

使用--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)

OSError: [WinError 193] %1 is not a valid Win32 application

我已经搜索了这个问题差不多2天但没有解决它。

我使用的是Windows 10 64位。

打开opencv\platforms\js\build_js.py文件，并替换此行：

ret = subprocess.check_output([os.path.join(emscripten_dir, "emcc"), "--version"])

用这个：

ret = subprocess.check_output([os.path.join(emscripten_dir, "emcc.bat"), "--version"])

希望这将在下一个opencv版本中修复。

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