我已经在新的 iMac(运行 Big Sur)上按照说明仔细安装了 Nativescript(来自https://docs.nativescript.org/environment-setup.html#macos-ios https://docs.nativescript.org/environment-setup.html#macos-ios).
昨天安装后工作正常,但今天我无法在 ios 模拟器(或 Android 虚拟设备)中运行应用程序。
The 国民警卫队医生终端中的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时(ns 创建) 然后尝试运行 (ns 运行 ios),我收到此错误:执行 webpack 失败,退出代码为 1。
错误消息以此开头:类型错误:无法读取未定义的属性“已解析”。
当我尝试在 Android 上运行它时,也会发生同样的事情。
尝试在 ios 和 Android 上运行后,国民警卫队医生添加这些行:
✔ 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.
所以看起来平台的添加是正确的。
任何帮助将不胜感激!
