找不到应用程序入口点文件。本机脚本

Question

我创建了 Angular 2 nativescript 项目并在添加 android 平台后，我运行该项目在连接的 nexus 6p 中 android 版本 7.1.1 以及何时部署到设备的应用程序出现此错误：

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.

知道如何解决这个错误吗？

更新：

我使用 tns create name --ng 创建项目，我只是运行使用 tns run android 命令。 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 文件夹中应该还有一个。它应该看起来像这样：

{
  "name": "name",
  "main": "app.js", //THIS IT THE ENTRYPOINT
  "version": "X.X.X",
  "author": {
    "name": "Name",
    "email": "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 typescript 文件），你应该可以开始了。

Answer 2

问题出在节点版本上，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，我在测试和子应用程序中有它，我在 tsconfig 中排除了它，现在它可以工作了

Answer 4

在我的例子中，它与我的 NativeScript CLI 版本有关。更新版本，问题解决。仅供参考，我在 angular-cli 7.3.6 和 NativeScript-cli 5.4.0（得到问题）更新到 NativeScript-cli 5.4.2 以解决问题。遇到类似问题的任何人，请尝试更新您的 NativeScript CLI 版本。
