Java ANDROID_SDK_ROOT=JDK 8的未定义（推荐设置）需求检查失败

我正在用爱奥尼亚和科尔多瓦开发android应用程序。当我运行这个命令时：sudo ionic cordova build android我有以下问题：

ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=/Users/macbook/Library/Android/sdk (DEPRECATED)
Requirements check failed for JDK 8 ('1.8.*')! Detected version: 14.0.1
Check your ANDROID_SDK_ROOT / JAVA_HOME / PATH environment variables.

我遵循并应用了stackoverflow上的所有答案，但当我想构建android应用程序时，我仍然有同样的问题

有什么想法吗？

首先，您的.bash\u配置文件将大多数VAR导出两次，这是错误的。但最主要的是，对于交互式shell，~/.bash_概要文件不会执行。幸运的是~/.bashrc是从那里导出的。

我终于解决了这个问题。我编辑了~/.bash_配置文件

添加$GRADLE_HOME root文件夹以避免此问题非常重要

然后

谢谢你的回答。我是Mac os Catalina的新手。当我写~/.bashrc时，zsh:permission denied:/Users/macbook/.bashrc我必须做什么？当我编辑.bash_配置文件时，我执行以下步骤。打开-文本编辑~/.bash\u配置文件，然后源~/.bash\u配置文件bashrc不是可执行文件。如果你想重新加载它，你需要像这样设置源代码：source~/.bashrci也有同样的问题
