找不到应用程序入口点文件。 nativescript

Question

我创建了Angular 2 nativescript项目，在添加了android平台之后，我在一个连接的nexus 6p中使用android版本7.1.1运行该项目，当应用程序部署到设备时，我收到此错误：

An uncaught Exception occurred on "main" thread.
java.lang.RuntimeException: Unable to create application com.tns.NativeScriptApplication: com.tns.NativeScriptException: Application entry point file not found.

任何想法我怎么能解决这个错误？

更新：

我使用tns create name --ng创建项目，我只需使用tns run android命令运行它。 package.js文件：

{
    "description": "NativeScript Application",
    "license": "SEE LICENSE IN <your-license-filename>",
    "readme": "NativeScript Application",
    "repository": "<fill-your-repository-here>",

Answer 1

您发布的package.json文件是错误的。

app文件夹中应该有另一个。应该看起来像这样：

{
  "name": "name",
  "main": "app.js", //THIS IT THE ENTRYPOINT
  "version": "X.X.X",
  "author": {
    "name": "Name",
    "email": "[email protected]"
  },
  "description": "some desc!",
  "repository": {
    "url": "https://github.com/yourrepo"
  }
}

验证入口点文件是否存在（它必须是.js文件而不是打字稿文件），你应该好好去。

Answer 2

问题是从节点版本，我更新了节点，问题解决了！

Answer 3

入口点在angular.json中定义

"architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/output",
            "index": "src/index.html",
            "main": "src/main.ts",

但是如果我们有任何编译错误就会发生这样的错误，我将它与测试和子应用程序一起使用，我在tsconfig中将其排除，现在它可以正常工作
