即使JRE 8安装在我的MAC OS Yosemite 10.10.3，而运行Android目前的工具在sdk -错误-“没有Java运行时目前，请求安装”会显示在终端-我如何解决这个问题?
我想安装Xamarin测试记录器-安装后 让我安装Android sdk SDK下载路径:Library/Developer/Xamarin/android-sdk 现在当我在工具文件夹中运行Android时，我得到了错误 没有Java运行时 我已经安装了JRE 8，并得到了验证 Java版本从他们的网站
有人能帮帮我吗!!
当前回答
通过以下命令工作
export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"
其他回答
下面是在macos mojave 10.14.6版本上为我工作的
我安装了当前的jdk(https://www.oracle.com/java/technologies/javase-downloads.html)
然后分别做;
vim . bash_profile 在bash_profile中添加export JAVA_HOME=$(/usr/libexec/ JAVA_HOME 源. bash_profile
完成了。可以使用java -version命令查看版本。
Pre-Requisite:
我已经在我的机器上使用brew安装了java11。
步骤1:酿造信息java11
输出:
/选择/自制/酒窖/openjdk@11
USER1-MacBook-Pro JavaVirtualMachines % brew info java11
openjdk@11: stable 11.0.12 (bottled) [keg-only]

==> Dependencies
Build: autoconf ✔
==> Requirements
Build: Xcode ✘
==> Caveats
For the system Java wrappers to find this JDK, symlink it with
sudo ln -sfn /opt/homebrew/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk
openjdk@11 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.
If you need to have openjdk@11 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc
For compilers to find openjdk@11 you may need to set:
export CPPFLAGS="-I/opt/homebrew/opt/openjdk@11/include"

步骤2:将openJDK路径附加到现有路径。
echo 'export PATH="/opt/homebrew/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc . bin:$PATH
步骤3:源现有shell或打开新终端以验证更改
来源 ~/.zshrc
步骤4:添加检查路径
而java
输出:/ opt /自制/ opt / openjdk@11 / bin / java
步骤5:
java——版本

如果在尝试生成jks文件(密钥库)时遇到错误，那么尝试添加
/Applications/Android\ Studio.app/Contents/jre/Contents/Home/bin/keytool
在运行命令之前，像这样:
/Applications/Android\ Studio.app/Contents/jre/Contents/Home/bin/keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
2022年:
一旦安装了Android Studio，就不需要再下载Java了。
尽管Java 11现在已经嵌入到Android Studio中，但在Mac上有时会出现这个问题，无法找到Java运行时。
所以，我通过以下两步解决了这个问题:
In Android Studio go to File > Project Structure. If, under the SDK entry, you can see there is no default SDK selected, but a text in red "No SDK", click on it and you will find an SDK / JDK list, select one of them. Thats it. Make sure you run Android Studio from Application Folder. For this copy the Android Studio launcher to the Application folder. Then in the Finder, go to the Application folder. Right-click on it. Click on "Show package contents", then navigate up to jre folder. Copy the folder and paste it into your home folder.
现在在终端上设置路径:你可以创建一个名为java_jre的文件夹，路径必须设置为jre/contents/Home:
Noors-Mac-mini:bin noorhossain$ export JAVA_HOME="/Users/noorhossain/java_jre/jre/Contents/Home"
//现在检查版本:
Noors-Mac-mini:bin noorhossain$ java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+0-b60-7772763)
OpenJDK 64-Bit Server VM (build 11.0.11+0-b60-7772763, mixed mode)
在使用brew安装openjdk并运行brew info openjdk后，我得到了这个
从那里我得到了这个命令，在运行它之后，我得到了Java工作
-操作系统?jdk / Library / Java / JavaVirtualMachines openjdk jdk。
