我正在尝试从Angular 6升级到Angular 7到Angular8。所以我更新了软件包和其他内容。新的Package.json文件如下所示
但是当我现在尝试npm start时。我收到此错误：
ERROR in Tried to overwrite C:/Source/nien/vital10-frontend/node_modules/ng2-dragula/dist/components/dragula.directive.d.ts.__ivy_ngcc_bak with an ngcc back up file, which is disallowed.
** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **
i ｢wdm｣: Failed to compile.
好的，我的packackage.json文件现在看起来像这样：

但随后出现此错误：

我从tsconfig.json中注释了AngularCompilerOptions，如下所示：
{
"compileOnSave": false,
"compilerOptions": {
"outDir": "./dist/out-tsc",
"baseUrl": "src",
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2016",
"dom"
]
},
// "angularCompilerOptions": {
// "enableIvy": true
// }
}
但是还是红色错误。
如何运行该应用程序。现在的版本是：8.1.2。
但仍然会收到以下警告：
./ node_modules / typescript / lib / typescript.js 94814：19-45中的警告 关键依赖项：依赖项的请求是一个表达式
WARNING in ./node_modules/source-map-support/source-map-support.js

i ｢wdm｣: Compiled with warnings.
如果我这样做：
"angularCompilerOptions": {
"enableIvy": true
}
}
比我还不能编译。但是，如果我启用enableIvy，则为false。然后就可以了
