Angular 7 + Ionic 4 build failing "TypeError: Cannot read properties of undefined (reading 'kind')"

Question

我需要一些帮助来解决构建我的 Angular 7 和 Ionic 4 应用程序的问题...

如果我运行 ng build --prod 命令出现以下错误：

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):
TypeError: Cannot read properties of undefined (reading 'kind')

这是我的 package.json 文件：

我已经在谷歌上搜索这个问题几个小时了，但不知道该怎么做。这是我的第一个 Angular + Ionic 应用程序，所以我还在学习中...我做错了什么？我应该使用不同的构建命令吗？

Answer 1

在开发我的第一个 Angular 应用程序时，我一直在处理这个问题。网上没查到怎么处理这个问题，我试了没解决这个错误。直到我进入生产环境（错误似乎根本没有出现），然后我发现了 buildOptimizer.

我们正在开发 angular 7 应用程序 - 我有 Angular 的全球版本 13.0，所以版本不匹配 - 在我同事的电脑上，他安装了 ang7，他也没有得到错误。所以我假设这是因为版本不匹配。

此处包含 angular.json 的片段，在哪里可以找到 buildOptimizer。请注意，您必须将其从 true 更改为 false.
