如何在生产模式下构建离子应用程序,离子构建的行为有所不同
N S*_*rma 8 javascript build ionic-framework ionic3 angular
我正在构建我的Ionic应用程序以进行生产.为此,我正在使用ionic build --prod命令并且应用程序正在成功构建,但是当我在服务器上运行我的应用程序时,它给出了以下错误:
cordova.js,main.js,Vendor.js.
(请忽略Firebase的错误)
网络标签的屏幕截图是:
当我看到我的构建文件夹时,运行上述离子命令即Pollyfills.js'sw-toolbox.js' 后只生成两个文件.
但是,当我使用Ionic serve命令,然后build文件夹中包含的所有文件即Pollyfills.js,main.js,main.css,vendor.js和"SW-toolbox.js".
我已经尝试了各种命令,如:
ionic cordova build android --prod --release 但它也导致Build文件夹中只有两个文件,因此在控制台上出错.
问题是什么以及如何使此应用适合生产模式.
请查看我的index.html文件,其中我给出了各种js文件的路径:

我已经找到了我的问题的解决方案。我去了 node_modules -> @ionic -> app-scripts -> config -> webpack.config
在该文件中，我注释了一行代码：
function getProdLoaders() {
if (process.env.IONIC_OPTIMIZE_JS === 'true') {
// 返回optimizedProdLoaders；<=这个
}
return devConfig.module.loaders;
}
现在，它正在发挥作用。
