Deployment of Node native modules to Azure WebSites,I'm experiencing some problems - node.js

Question

I deploy a node application to the Azure website.
The tricky part is that I'm using a node module called "opencv" that needs to be compiled at install time using node-gyp.
I use the node-gyp rebuild --arch=ia32 command to compile it int the windows10. But when I used it in the Azure website， I get following problem:
Wed Apr 26 2017 04:48:35 GMT+0000 (Coordinated Universal Time): Application has thrown an uncaught exception and is terminated:
Error: The specified module could not be found.
\\?\D:\home\site\wwwroot\app\api\lib\opencv.node
at Error (native)
at Object.Module._extensions..node (module.js:434:18)
at Module.load (module.js:343:32)

at Module._compile (module.js:409:26)
at Object.Module._extensions..js (module.js:416:10)
at Module.load (module.js:343:32)
This is the code I call：
'use strict';
var fs = require('fs');
var path = require('path');
var opencv = require("./opencv.node");
function isContains(str, substr) {
return new RegExp(substr).test(str);
}
module.exports = {
post: function (imageInfo, data) {
if (isContains(imageInfo.imageName, ".yuv")) {
var imageName = imageInfo.imageName.substr(0, imageInfo.imageName.length - 3) + "jpg";
opencv.yuvToJpeg(path.resolve(__dirname, "../../image/" + imageName), imageInfo.width, imageInfo.height, Array.prototype.slice.call(data, 0));
} else if (isContains(imageInfo.imageName, ".jpg")) {
fs.writeFileSync(path.resolve(__dirname, "../../image/" + imageInfo.imageName), data);
}
return "success";
}
};
But that file is in-fact deployed on the server:
Please help me, and tell me what to do

Answer 1

Its readme says that "You'll need OpenCV 2.3.1 or newer installed before installing node-opencv". And as Azure Web Apps is a Software as a service (SaaS), we don't have the privilege to install arbitrary software there. But if that is a requirement for you, you'll need to use an alternative offering, like Cloud Service or VM.
