我正在尝试把我的第一个Flutter应用部署到VS Code、IntelliJ或 Android Studio的 Android模拟器上。它们都给出同样的错误。我一直在查找解决方法，但找不到。尝试在一个中等配置的Android模拟器上进行部署。我的应用在网页版本上运行正常。第一次尝试时，我的电脑崩溃了。自那以后，即使执行flutter clean也会出现这个错误。我已经运行过flutter doctor，结果显示一切正常，除了未安装Visual Studio。我也尝试过重新创建Android文件夹，但没有效果。

Many more lines like the prolog line above. Here is my pubspec.yaml

description: "A new Flutter project."
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
version: 1.0.0+1

environment:
  sdk: ^3.9.2

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.8
  http: ^1.5.0
  flutter_stripe: ^12.4.0
  flutter_stripe_web: ^7.4.0
  shared_preferences: ^2.5.4


dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^6.0.0

flutter:
  uses-material-design: true
  assets:
    - assets/images/


And my build.gradle.kts

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

val newBuildDir: Directory =
    rootProject.layout.buildDirectory
        .dir("../../build")
        .get()
rootProject.layout.buildDirectory.value(newBuildDir)

subprojects {
    val newSubprojectBuildDir: Directory = newBuildDir.dir(project.name)
    project.layout.buildDirectory.value(newSubprojectBuildDir)
}
subprojects {
    project.evaluationDependsOn(":app")
}

tasks.register<Delete>("clean") {
    delete(rootProject.layout.buildDirectory)
}

解决方案

我曾经遇到过这个错误一次 我通过修改Kotlin Gradle插件版本和AGP版本来解决的

但如果仍然不行，可以尝试在另一台电脑上运行你的项目。
