ANDROID_SDK_ROOT=undefined（推荐设置）JDK 8 需求检查失败

Question

我正在使用 IONIC 和 Cordova 构建 android 应用程序。 当我运行此命令时： sudo ionic cordova build android l 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.

我按照我的问题在stackoverflow上应用了所有答案，但是当我想构建android应用程序时我仍然遇到同样的问题。

有什么想法吗？

Answer 1

最后我解决了。 我编辑了~/.bash_profile

export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_251`
export PATH=$JAVA_HOME/bin:$PATH
export ANDROID_HOME=/Users/dylan/Library/Android/sdk
export ANDROID_SDK_ROOT=/Users/dylan/Library/Android/sdk
export ANDROID_AVD_HOME=/Users/dylan/.android/avd
export PATH=${PATH}:/$ANDROID_HOME/platform-tools:/$ANDROID_HOME/tools:/$ANDROID_HOME/tools/bin
export ANDROID_HOME=~/Library/Android/sdk
export ANDROID_SDK_ROOT=~/Library/Android/sdk
export ANDROID_AVD_HOME=~/.android/avd
export GRADLE_HOME=~/Development/gradle-6.5.1/bin
// Carefully add $GRADLE_HOME folder root . 
export PATH="$PATH:$ANDROID_HOME:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$GRADLE_HOME"

添加$GRADLE_HOME根文件夹以避免此问题非常重要

然后

source ~/.bash_profile 

Answer 2

首先，您的.bash_profile将大部分 var 导出两次，这是错误的。 但最主要的是，对于交互式 shell， ~/.bash_profile文件没有执行。 幸运的是~/.bashrc是从那里导出的。
