Question

我创建了Angular 2 nativescript项目，在添加了android平台后，我在一个连接的nexus 6p中使用android版本7.1.1运行该项目，当app部署到设备时，我收到了这个错误：

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.

任何想法如何解决这个错误？

更新

我使用tns create name --ng创建项目，然后使用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>",
    "nativescript": {
        "id": "org.nativescript.Bazim",
        "tns-android": {
            "version": "2.4.1"
        }
    },

Answer 1

您发布的package.json文件错误。

app文件夹中应该有另一个。看起来应该是这样的：

{
  "name": "name",
  "main": "app.js", //THIS IT THE ENTRYPOINT
  "version": "X.X.X",
  "author": {
    "name": "Name",
    "email": "some@email.com"
  },
  "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

问题来自节点版本，我更新了节点并解决了问题！

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，我在测试和子应用程序中都遇到过，我在tsconfig中将其排除，现在它可以工作了

Answer 4

就我而言，它与我的NativeScript CLI版本有关。更新了版本，问题已解决。仅供参考，我将angular-cli 7.3.6和NativeScript-cli 5.4.0（已解决问题）更新为NativeScript-cli 5.4.2以解决此问题。任何面临类似问题的人，请尝试更新您的NativeScript CLI版本。

找不到应用程序入口点文件。 nativescript
