我想一些帮助与建设我的Angular 7和离子4应用程序的问题...
如果运行ng build --prod命令，则会出现以下错误：
ERROR in ./node_modules/ionic4-auto-complete/fesm5/ionic4-auto-complete.js
Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):

在开发我的第一个Angular应用程序时，我一直在处理这个问题。在互联网上找不到如何处理这个问题的地方，我尝试过，但没有解决这个错误。直到我进入生产（在生产中，这个错误似乎根本没有出现），然后我发现了buildOptimizer。
我们当时正在开发angular 7应用程序--我的Angular是全球13.0版本，所以出现了版本不匹配的问题--在我同事的电脑上，他安装了ang 7，但也没有收到错误。所以我想这是因为版本不匹配。
这里包含angular.json的片段，在这里可以找到buildOptimizer。注意，你必须将它从true改为false。
