Question

我正在尝试构建 pwa。所以先运行 ng add @angular/pwa 效果很好。

但是 ionic build --prod 失败了

This version of CLI is only compatible with Angular versions 0.0.0 || ^11.0.0-beta || >=11.0.0 <12.0.0,
but Angular version 9.1.13 was found instead.

Please visit the link below to find instructions on how to update Angular.

我在这里缺少什么？

Answer 1

看起来您必须安装一些软件包才能使其正常工作。

sudo npm install -g ionic cordova native-run cordova-res
cordova platform rm android
cordova platform add android
ionic cordova run android --prod

Answer 2

卸载当前的angular cli：

npm uninstall @angular/cli

在其版本 10.2.1 中安装 angular cli：

npm install @angular/cli@10.2.1 --save-dev

由于 Angular 版本，离子构建失败
