如何将路径更改为正确的路径...

/usr/lib/jvm/jdk-21.0.5-oracle-x64/bin

许多解决方案都指向安装 Android Studio（确实如此）并安装 Android SDK 命令行工具（最新）。安装了命令行工具，并且 Android Studio > SDK 工具对话框中的复选框验证了这一点。

我认为 Java 的路径需要修改......出于某种奇怪的原因，它在末尾添加了“/javac/bin/java”。不知道那是从哪里来的！

Answer 1

您可以更新路径

1. 打开终端并运行以下命令来编辑.bashrc文件：

   纳米~/.bashrc

2. 查找任何错误地将 Java 添加到您的 PATH 的行，并删除任何引用 /javac/bin/java 的行。

   导出 PATH=$PATH:/usr/lib/jvm/jdk-21.0.5-oracle-x64/bin

3. 保存并重新加载文件

   源~/.bashrc

4. 再次运行 Flutter doctor 来确认您的环境
