如何解决NativeScript Android 构建错误 - “版本无效:空”
我有一个 NativeScript 项目 (repo here),当我使用以下命令在 ios 模拟器上运行它时运行良好:
tns run ios
我现在正尝试在带有 tns run android
的 android 模拟器上运行它,但我不断收到错误消息“无效版本:null”,没有其他消息或解释...
我使用的是 mac 10.15.6 并安装了此版本的 Android Studio 和 sdk:
Android Studio 4.1.1
Build #AI-201.8743.12.41.6953283,built on November 4,2020
Runtime version: 1.8.0_242-release-1644-b3-6915495 x86_64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.15.6
GC: ParNew,ConcurrentMarkSweep
Memory: 1237M
Cores: 8
Registry: ide.new.welcome.screen.force=true,external.system.auto.import.disabled=true
这是我的 tns info
输出:
✔ Getting NativeScript components versions information...
⚠ Update available for component nativescript. Your current version is 7.0.8 and the latest available version is 7.0.12.
✔ Component tns-core-modules has 6.5.24 version and is up to date.
✔ Component tns-ios has * version and is up to date.
✔ Component tns-android has * version and is up to date.
我使用这些命令创建了一个新的 android 模拟器设备:
cd $ANDROID_HOME/tools/bin
avdmanager create avd -n test -k "system-images;android-25;google_apis;x86"
并接受许可。当我运行 avdmanager list
时,我可以看到大量的 android 设备模拟器:
bin ★ avdmanager list

但是,当我运行 tns device

当我尝试运行 tns run android
或 tns platform add android
时出现此错误:
Invalid Version: null
感谢有关如何通过此测试并为 ios 和 android 模拟器构建应用程序的任何建议。谢谢!
