Answer 1

尝试安装 - npm install @ionic/cordova-builders

然后转到“ionic-cordova-build”和“ionic-cordova-serve”内的 angular.json 和 替换

"builder": "@ionic/angular-toolkit:cordova-build"

为

"builder": "@ionic/cordova-builders:cordova-build"，

Answer 2

以下解决方案对我有用：

步骤：1

• npm install @ionic/angular-toolkit@latest @ionic/cordova-builders

步骤：2

• 替换 angular.json 中的以下代码

•  "builder": "@ionic/angular-toolkit:cordova-build",
  

•  "builder": "@ionic/cordova-builders:cordova-serve",
  

步骤：3 - 非强制

• 删除node_module并重新安装

Answer 3

我使用这个解决方案解决了这个问题。

1. 运行
   sudo npm install -g @ionic/cli@latest
   安装最新的 ionic 包并运行
   npm 已过时
   获取过时的软件包。
2. 运行
   对于过时软件包列表中显示的每个软件包，npm install package_name@latest --force（将“package_name”替换为过时的软件包名称）
3. 忽略更新期间的任何警告。

   < br>
   提示：更新所有过时的软件包可以避免应用性能低下并提高安全性

Answer 4

供将来参考：这里有解释以及如何修复它。我还需要编辑 angular.json 来更改 cordova 构建器。

Answer 5

尝试安装 - npm install @ionic/cordova-builders

然后转到 angular.json 并替换

@ionic/angular-toolkit

为

@ionic/cordova-builders

The angular.json will be like this:

        "ionic-cordova-serve": {
          "builder": "@ionic/cordova-builders:cordova-serve",
          "options": {
            "cordovaBuildTarget": "app:ionic-cordova-build",
            "devServerTarget": "app:serve"
          },
          "configurations": {
            "production": {
              "cordovaBuildTarget": "app:ionic-cordova-build:production",
              "devServerTarget": "app:serve:production"
            }
          }
        },
        "ionic-cordova-build": {
          "builder": "@ionic/cordova-builders:cordova-build",
          "options": {
            "browserTarget": "app:build"
          },
          "configurations": {
            "production": {
              "browserTarget": "app:build:production"
            }
          }
        }
