Question

我正在尝试在linux上设置OPENCV.js.但是我在Empscripten路径上遇到了令人愤怒的问题。我正在关注此文档：https://docs.opencv.org/3.3.1/d4/da1/tutorial_js_setup.html

1-）我下载empscripten并执行以下代码。

./emsdk update
./emsdk install latest
./emsdk activate latest

2-）设置环境路径

source ./emsdk_env.sh

3-）用git克隆opencv

git clone https://github.com/opencv/opencv.git

4-）构建此目录（/ root / Downloads / opencvjspackage）

 python ./platforms/js/build_js.py /root/Downloads/opencvjspackage

我在第4部分得到了这个输出

root@kali:~/Downloads/opencvjs/opencv# python ./platforms/js/build_js.py /root/Downloads/opencvjspackage
Args: Namespace(build_dir='/root/Downloads/opencvjspackage', build_doc=False, build_test=False, build_wasm=False, clean_build_dir=False, config_only=False, emscripten_dir=None, enable_exception=False, opencv_dir='/root/Downloads/opencvjs/opencv', skip_config=False)
Cannot get Emscripten path, please specify it either by EMSCRIPTEN environment variable or --emscripten_dir option.

我试试这个

python ./platforms/js/build_js.py /root/Downloads/opencvjspackage --emscripten_dir=/root/Downloads/emsdk-portable/emscripten/1.37.33

获得此输出：

usage: build_js.py [-h] [--opencv_dir OPENCV_DIR]
                   [--emscripten_dir EMSCRIPTEN_DIR] [--build_wasm]
                   [--build_test] [--build_doc] [--clean_build_dir]
                   [--skip_config] [--config_only] [--enable_exception]
                   build_dir
build_js.py: error: too few arguments

Answer 1

=和Empscripten路径之间不应该有--emscripten_dir。输出文件夹也应该是最后一个参数。试试这样：

python ./platforms/js/build_js.py --emscripten_dir /root/Downloads/emsdk-portable/emscripten/1.37.33 /root/Downloads/opencvjspackage

提示：确保/root/Downloads/opencvjspackage存在，并且您希望将opencv.js置于其中。还要确保已安装cmake。

OPENCV.js无法获得Emscripten路径
