Android Studio 电鳗：javaHome 似乎无效

Question

我正在开发一个 React Native - TypeScript 移动应用程序。我更新了 Android Studio，这破坏了我的应用程序的构建。我花了几个小时，但无法解决不断出现的 JAVA_HOME 错误。需要帮忙。

安装的Android Studio：

Android Studio Electric Eel | 2022.1.1
Build #AI-221.6008.13.2211.9477386, built on January 11, 2023

Registry:
    external.system.auto.import.disabled=true
    ide.text.editor.with.preview.show.floating.toolbar=false

JAVA_HOME被设定为C:\Program Files\Java\jdk-19。我可以更改为C:\Program Files\Android\Android Studio\jbr具有\bin\java.exe.

运行时出错react-native run-android：

info Starting JS server...
info Installing the app...

Answer 1

对于Windows：

问题是因为旧 Android Studio java 文件夹的痕迹，只需删除该文件夹即可开始工作：

C:\Program Files\Android\Android Studio\jre

新的 Android Studio Electric Eel 使用的是 jbr，而不是 jre。

对于macOS，如 @Jayanth 上面回复的：如果您使用的是 macOS，请替换 .bash_profile 或 .zshrc 中的路径

export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"

和

export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"

Answer 2

更新 android studio 后，我的 Kotlin Android 项目也遇到了同样的问题。这似乎是一个错误。以下步骤对我有用：

1. 更新JAVA_HOME至C:\Program Files\Android\Android Studio\jbr

2. 打开文件资源管理器并导航到C:\Program Files\Android\Android Studio\jbr并复制所有内容并将其粘贴到C:\Program Files\Android\Android Studio\jre

3. 重新启动您的电脑并尝试再次运行该项目。

Answer 3

如果您使用 MAC，请替换 .bash_profile 或 .zshrc 中的路径

export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"

和

export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"
