错误：wasm的异步和同步获取均失败

Question

我正在IONIC4中开发混合应用程序。对数据库使用typeorm。重叠错误

core.js:9110 ERROR Error: Uncaught (in promise): abort("abort(\"both async and sync fetching of the wasm failed\"). Build with -s ASSERTIONS=1 for more info."). Build with -s ASSERTIONS=1 for more info.

我在Google搜索了很多东西。我浪费了时间。但是没有得到任何解决方案。请给我建议。

Answer 1

将已编译的文件（starfield.html，starfield.js，starfield.wasm）放入Web服务器并使用http运行。

Answer 2

Angular 12 和 ionic 5 也有同样的问题，我认为这可能是由 webpack 和 sql.js 引起的。这里是我的 custom.webpack.config.js：

const webpack = require('webpack');
console.log('The custom config is used');
module.exports = {
    plugins: [
        new webpack.ProvidePlugin({
            'window.SQL': 'sql.js/dist/sql-wasm.js'
        }),
        new webpack.NormalModuleReplacementPlugin(/typeorm$/, function (result) {
            result.request = result.request.replace(/typeorm/, "typeorm/browser");
        })
    ],
   
    resolve: {
        fallback: {
          fs: false,
          net: false,
          tls: false
        }
      }
};
