package.json根据以下内容更改

 "dependencies": {
            "@angular/common": "4.4.3",
            "@angular/compiler": "4.4.3",
            "@angular/compiler-cli": "4.4.3",
            "@angular/core": "4.4.3",
            "@angular/forms": "4.4.3",
            "@angular/http": "4.4.3",
            "@angular/platform-browser": "4.4.3",
            "@angular/platform-browser-dynamic": "4.4.3",                
            "@ionic-native/splash-screen": "3.12.1",
            "@ionic-native/status-bar": "3.12.1",                
            "@ionic/storage": "2.0.1",
            "ionic-angular": "3.7.0",
            "ionic-plugin-keyboard": "^2.2.1",
            "ionicons": "3.0.0",
            "rxjs": "5.4.3",
            "sw-toolbox": "3.6.0",                
            "zone.js": "0.8.17",
            // ...
        },
        "devDependencies": {
            "@ionic/app-scripts": "3.0.0",
            "typescript": "2.3.4"
        },

然后只是（不要忘记node_module从项目目录中删除该文件夹）

npm install

完毕 ：）
