为什么酿造的分期付款失败了？

Question

我使用家庭啤酒安装了java11，但失败了。因此，需要一些帮助才能使Java工作！

谢谢你的提前！

admin@mac ~ % brew install java11
Warning: openjdk@11 11.0.12 is already installed and up-to-date.
To reinstall 11.0.12, run:  
brew reinstall openjdk@11

然后brew重新安装java11

 admin@mac  ~ % brew reinstall java11

    ==> Reinstalling openjdk@11
    ==> Pouring openjdk@11--11.0.12.arm64_big_sur.bottle.tar.gz
    ==> 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"
    
    ==> Summary
      /opt/homebrew/Cellar/openjdk@11/11.0.12: 670 files, 273.0MB
    ==> Running `brew cleanup openjdk@11`...
    Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
    Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

重新安装后：

   admin@mac ~ % echo 'export PATH="/opt/homebrew/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc

和测试java -version

admin@mac ~ % java -version
The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.

另外：

admin@mac ~ %  sudo ln -sfn /opt/homebrew/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk
Password:
ln: /Library/Java/JavaVirtualMachines/openjdk-11.jdk: No such file or directory

Answer 1

/Library/Java/JavaVirtualMachines/openjdk-11.jdk：：

没有这样的文件或目录

链接命令的目的是在指定的目录中创建文件openjdk-11.jdk。这个错误表明这个目录实际上并不存在。

尝试创建目录/Library/Java/JavaVirtualMachines/并重新运行链接命令。
