cordova 在运行项目时失败 - 未找到已安装的构建工具 - 未指定 compileSdkVersion

Question

我创建了一个新的 cordova 项目，但它没有启动。 我按照下面描述的步骤进行操作：

创建项目：

PS D:\MyProjects> npm install -g cordova
PS D:\MyProjects> cordova create mycordova

添加平台：

PS D:\MyProjects> cd mycordova
PS D:\MyProjects\mycordova> cordova platform add browser
PS D:\MyProjects\mycordova> cordova platform add android

设置环境：

PS D:\MyProjects\mycordova> $env:JAVA_HOME="C:\Program Files\Java\jdk8"
PS D:\MyProjects\mycordova> $env:ANDROID_SDK_ROOT="C:\Program Files\Android\Android Studio"
PS D:\MyProjects\mycordova> $env:GRADLE="C:\Gradle\gradle-7.0"
PS D:\MyProjects\mycordova> $env:SDKTOOLS="C:\Users\robin\AppData\Local\Android\Sdk\tools"
PS D:\MyProjects\mycordova> $env:PLATFORMTOOLS="C:\Users\robin\AppData\Local\Android\Sdk\platform-tools"
PS D:\MyProjects\mycordova> set-item -path env:path -value ($env:JAVA_HOME + "\bin;" + $env:ANDROID_SDK_ROOT + "\bin;" + $env:GRADLE + "\bin;" + $env:SDKTOOLS + ";" + $env:SDKTOOLS + "\bin;" + $env:PLATFORMTOOLS + ";" + $env:path)

验证先决条件：

PS D:\MyProjects\mycordova> cordova requirements

Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: installed android-30,android-29
Gradle: installed C:\Gradle\gradle-7.0\bin\gradle.BAT

Requirements check results for browser:

运行项目和结果：

PS D:\MyProjects\mycordova> cordova run android
Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=C:\Program Files\Android\Android Studio (recommended setting)
ANDROID_HOME=undefined (DEPRECATED)
Using Android SDK: C:\Program Files\Android\Android Studio
Subproject Path: CordovaLib
Subproject Path: app

NPM版本是6.14.2和NODE版本是14.16.1 。 在Windows 10上。

你能帮我找出为什么项目没有启动吗？

Answer 1

找到了一个解决方案，从

$env:ANDROID_SDK_ROOT="C:\Program Files\Android\Android Studio"

至

$env:ANDROID_SDK_ROOT="C:\Users\robin\AppData\Local\Android\Sdk"

添加

$env:BUILDTOOLS="C:\Users\robin\AppData\Local\Android\Sdk\build-tools"

并从

set-item -path env:path -value ($env:JAVA_HOME + "\bin;" + $env:ANDROID_SDK_ROOT + "\bin;" + $env:GRADLE + "\bin;" + $env:SDKTOOLS + ";" + $env:SDKTOOLS + "\bin;" + $env:PLATFORMTOOLS + ";" + $env:path)

至

set-item -path env:path -value ($env:JAVA_HOME + "\bin;" + $env:GRADLE + "\bin;" + $env:SDKTOOLS + ";" + $env:SDKTOOLS + "\bin;" + $env:PLATFORMTOOLS + ";" + $env:BUILDTOOLS + ";" + $env:PATH)
