二、问题列表
问题一:但是如果执行上面的命令出现下面的错误的话
MacBook-Pro ~ % brew install adoptopenjdk8
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/cask-versions).
==> Updated Casks
Updated 1 cask.
Error: Cask adoptopenjdk8 exists in multiple taps:
homebrew/cask-versions/adoptopenjdk8
adoptopenjdk/openjdk/adoptopenjdk8
我们就需要使用下面的命令进行安全
brew install adoptopenjdk/openjdk/adoptopenjdk8
