nativescript - Nativescript 错误：执行 webpack 失败，退出代码为 1

问题描述

我已经按照说明（来自https://docs.nativescript.org/environment-setup.html#macos-ios ）在新的 iMac（运行 Big Sur）上完成了 Nativescript 的全新安装。

昨天安装后运行良好，但今天我无法在 ios 模拟器（或 Android 虚拟设备）中运行应用程序。

终端中的ns doctor命令最初给了我这个：

No issues were detected.
✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ The Android SDK is installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Xcode is installed and is configured properly.
✔ xcodeproj is installed and is configured properly.
✔ CocoaPods are installed.
✔ CocoaPods update is not required.
✔ CocoaPods are configured properly.
✔ Your current CocoaPods version is newer than 1.0.0.
✔ Python installed and configured correctly.
✔ The Python 'six' package is found.
✔ Xcode version 12.5.1 satisfies minimum required version 10.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 8.0.2 version and is up to date.

但是，当我创建一个新应用程序（ns create）然后尝试运行（ns run ios）时，我收到此错误：Executing webpack failed with exit code 1。

错误消息以此开头：TypeError: Cannot read property 'resolved' of undefined。

当我尝试在 Android 上运行它时，也会发生同样的事情。

在尝试在 ios 和 Android 上运行它之后，ns doctor添加了这些行：

✔ Component @nativescript/core has 8.0.8 version and is up to date.
✔ Component @nativescript/ios has 8.0.0 version and is up to date.
✔ Component @nativescript/android has 8.0.0 version and is up to date.

所以看起来平台正在被正确添加。

任何帮助将不胜感激！

标签： nativescript

解决方案

感谢您报告此问题，我们已确认最新 webpack 版本中的重大更改： https ://github.com/webpack/webpack/releases/tag/v5.51.1

您现在可以切换您的 package.json 以使用rc以下方法来解决此问题：

"devDependencies": {
  ...
  "@nativescript/webpack": "rc"
},

然后ns clean，您现在应该可以运行您的应用程序了。

我们还发布了另一个beta将 webpack 固定到 5.50.0 的标签，因此ns clean在您自己的 package.json 中不进行任何其他依赖项更改的情况下现在也应该可以工作。
