【问题描述】：
Nativescript tns 医生告诉我 JDK 配置不正确，尽管看起来确实如此。
我目前在 Mac 上运行 Big Sur。 安装所有 iOS 和 Android 要求后，我不断从 TNS Doctor 收到此错误：
✖ Error executing command 'javac'. Make sure you have installed The Java Development Kit (JDK) and set JAVA_HOME environment variable.
您将无法为 Android 构建项目。 为了能够为 Android 构建，请确认您已安装 Java 开发工具包 (JDK) 并根据系统要求将其配置为 描述于http://docs.nativescript.org/setup/ns-cli-setup/ns-setup-os-x.html#system-requirements
✖ 警告：Java 开发工具包 (JDK) 未安装或配置不正确。
在我的 ~/.bash_profile 中，我将 JAVA_HOME 描述为：
export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"
我的整个 ~/.bash_profile：
Setting PATH for Python 3.9
The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}"
export PATH
export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"

除了 tns 错误，JAVA_HOME 似乎配置正确；运行 avdmanager 运行完美。
