nativescript - TNS Doctor - JDK 配置不正确？

问题描述

Nativescript tns doctor 告诉我 JDK 配置不正确，即使看起来是这样。

我目前在 Mac 上运行 Big Sur。安装完所有 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) 并按照http://docs.nativescript.org/setup/ns-cli-setup/ns-中所述的系统要求对其进行配置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)"
export ANDROID_HOME=/usr/local/share/android-sdk
export ANDROID_SDK_ROOT=/usr/local/share/android-sdk

打印环境：

除了 tns 错误，JAVA_HOME 似乎配置正确；运行 avdmanager 运行良好。

（不太确定像素设备是什么）

解决方案

我的 .bash_profile 文件中的这个设置对我有用：

export JAVA_HOME=$(/usr/libexec/java_home)
