离子移动开发；在 Ionic 中准备 android 时出错
Ionic mobile development; Error when preparing android in Ionic
我在添加 android 平台并准备 android 时遇到错误。
当我运行以下命令时：-
ionic capacitor add android
我收到以下错误：-
[error] "android" platform already exists.
To add a new "android" platform, please remove "D:\ionic\myapp\android"
and run this command again.
WARNING! your native IDE project will be completely removed. [ERROR] An error occurred while running subprocess capacitor.
capacitor.cmd add android exited with exit code 1.
我使用以下命令更新了 android：-
ionic capacitor update android
它更新了我的 android : -
capacitor.cmd update android √ Updating Android plugins in 73.77ms
Found 0 Capacitor plugins for android: √ update android in 473.61ms
Update finished in 0.593s
然后我尝试准备 android 在 Android 工作室开始 :-
ionic cordova prepare android
我收到以下错误：-
cordova.cmd platform add android --save Error: npm: Command failed with exit code 1 Error output: npm ERR! code ENOLOCAL npm ERR! Could
not install from "android" as it does not contain a package.json file.

code: 1 } [ERROR] An error occurred while running subprocess cordova.
cordova.cmd platform add android --save exited with exit code 1.
Re-running this command with the --verbose flag may provide more information.
我尝试删除 cordova 并重新安装。但它不起作用。
我有没有漏掉什么插件。我在项目的开头添加了电容器。
任何人都可以提出任何解决方案吗？
要在 Android Studio 上启动 ionic 应用程序，请执行以下命令。
ionic capacitor run android
