1 scala 2.11.12下载
brew search scala
scala scala@2.11 scala@2.12 ✔ scalaenv scalapack scalariform scalastyle
brew install scala@2.11
==> Caveats
scala@2.11 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have scala@2.11 first in your PATH run:
echo 'export PATH="/usr/local/opt/scala@2.11/bin:$PATH"' >> ~/.bash_profile
==> Summary
🍺 /usr/local/Cellar/scala@2.11/2.11.12: 51 files, 31.3MB, built in 58 seconds
scala安装完成。
