OSError：[WinError 193]％1不是有效的Win32应用程序opencv.js [英] OSError: [WinError 193] %1 is not a valid Win32 application opencv.js

问题描述

我尝试从 opencv.js 。 htmlrel =nofollow noreferrer>教程在他们的页面上。

I have tried to build opencv.js from the tutorial on their page.

我已经完成了除最后一个步骤之外的所有步骤来构建它：

I have done all the steps except the last one to build it:

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

- emscripten 选项，但我得到了这个：

with the --emscripten option but I got this instead:

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。

I have searched for this problem for almost 2 days but nothing solve it.

我正在使用Windows 10 64位。

I'm using Windows 10 64bit.

推荐答案

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

Open opencv\platforms\js\build_js.py file, and replace this line:

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

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。

Hope this will be fixed in next opencv version.
