如何在 Nativescript-Vue 中调试 webpack 'Executing webpack failed with exit code 0'

Question

我尝试将 Nativescript-Vue 项目从 NativeScript 版本 6.2.1 更新到 6.5.0（在 upgrade instructions 之后）。尝试通过 "tns run android" 运行项目失败，关于原因的信息很少：

File change detected. Starting incremental webpack compilation...

webpack is watching the files…

Executing webpack failed with exit code 0

我对 webpack 了解不多，但 0 应该是成功的，对吧？无论如何，我认为导致构建失败的原因可能是某个地方被吞没的错误。因此，我尝试通过向 webpack-cli:s 代码（在 node_modules/.bin/webpack 中）添加数十个 console.logs 来进行调试，以查看是否发生了奇怪的事情。但是我找不到任何东西（我也不知道去哪里找）。只有一个地方 process.exit() 被显式调用而没有参数（退出代码默认为 0），但在我的情况下从未进行过该调用。

我想知道是否有一些方法可以在 NativeScript-vue 项目中调试 webpack 是否有用？我在配置中添加了 stats: 'verbose' 和 bail: true，但没有做任何事情。

以下是 package.json 中我认为相关的部分：

  "nativescript": {
    ...
    "tns-ios": {
      "version": "6.5.0"
    },
    "tns-android": {
      "version": "6.5.0"
    }
  },
  "dependencies": {
    ...
    "@vue/devtools": "^5.3.3",
    "nativescript": "^6.5.0",
    "nativescript-vue": "^2.5.1",
    "tns-core-modules-widgets": "^6.5.0",
    ...
  }
  "devDependencies": {
    ...
    "nativescript-dev-webpack": "~1.5.1",
    "nativescript-vue-template-compiler": "^2.5.1",
    "vue-loader": "^15.9.1"
    ...
  },

[编辑:]编译失败似乎是因为 NS 和 NativeScript-Vue 之间的兼容性问题，因为 NativeScript-Vue 2.5.1 依赖于旧版本的 NativeScript。

不过，我想知道是否有调试 webpack 的方法来找到导致编译失败的根源。

[Edit2:]更新到支持 NS 6.5.0 的 NS-Vue 2.6.1 但问题仍然存在。

使用 --log trace 选项会产生一些额外的日志行。以下为tnsrun android

Webpack process exited with code 0 when we expected it to be long living with watch.

Executing webpack failed with exit code 0.

运行 tns build android 产量：

有趣的是，调试日志显示 "Received result Success" 和 "build should be done"，但 gradlew 仍然失败。

问题原来是包 nativescript-worker-loader@0.11 中的错误。目前，该软件包需要降级到 v0.10 才能正常工作。
