OpenCV.js自定义生成在windows计算机中失败

Question

我正试图按照Open CV[官方文件][1]中提到的步骤构建opencv.js。

注意：我正在尝试进行自定义构建，而不是使用现有的[opencv.js][2]库，因为我也想添加一些contrib模块。

开放式简历源版本：4.5.1Cmake:32.00Python：3.7Emscriptem:[最新][3]操作系统：windows 64位

以下是我在windows powershell中尝试执行以下命令时遇到的问题的堆栈跟踪。。

emcmake python ./opencv/platforms/js/build_js.py build_js

堆栈跟踪

emcmake python ./opencv/platforms/js/build_js.py build_js

欢迎提出任何解决这一问题的想法。

Answer 1

在Windows上构建opencv.js将不起作用，至少根据这个悬而未决的问题。另一种选择是安装WSL并使用它进行构建。
