问题
First I installed macports
Then I installed Scala and Play through macports: To make sure installation works I run a "hello world" on eclipse. It works!
But since my objective is to use Intellij, I try to follow the instructions at http://confluence.jetbrains.com/display/SCA/Getting+Started+with+IntelliJ+IDEA+Scala+Plugin
On step 3 of the instructions (section
Creating a Project), underuse scala distribution, I am not sure what to type. Will someone please tell me what to type? I am using mac os x mountain lion. I don't know the path to my scala installation.
I appreciate the help. I have already looked at Intellij Idea setup for Scala, clarification needed. No help there. My Intellij version is 12.0.3 and my scala install is 2.10.
回答1:
I don't know OSX but presumably you can open a terminal, type ls -l `which scala` into it, and get the path to the scala executable.
You can then enter that path, without the /bin/scala on the end, into the intellij dialogue.
回答2:
Just for clarification: you can install scala in Mac OS X using Homebrew as @JasonG mentions:
$ brew install scala --with-docs
In that case, the selected solution won't work, as IntelliJ will still complain. Any way, as stated in the caveats of the formula, you will have a directory specially crafted for IntelliJ integration:
==> Caveats To use with IntelliJ, set the Scala home to: /usr/local/opt/scala/idea
Using this directory will make IntelliJ happy.
UPDATE for IntelliJ IDEA 13.x users: This doesn't seem to be needed any more. Just use SBT based projects, and everything will be downloaded and configured automatically (Scala compiler and libraries)
回答3:
You're much better served by letting existing tools do this sort of thing for you.
Define your project using SBT. Use PaulP's (Paul Phillips) SBT launcher and the sbt-idea plug-in that provides automatic generation of IDEA project and module files.
See my previous answer for some details
回答4:
- find and install scala plugin in "Preference" -> "Plugins" -> "Browse repositories" -> "Scala"
- open project and
- open"Project Structure"
- open "Facets"
- press "Add" / "Plus icon"
- select "Scala"
Then you can select scala version and setup compiler
回答5:
I actually downloaded the scala and scala docs from typesafe, unzipped them in a folder as per the instructions, and then pointed intellij at that. Use the sbt plugin as well - it makes life much better.
Alternatively you can use brew to install scala with docs:
$ brew install scala --with-docs
2.9.2 instructions here should work. http://scalacookbook.blogspot.ca/2012/09/scala-for-intellij.html
As a third option, you can just let intellij download scala for you. If it's not found, there is a download button you can hit. I'm not sure if it gets the docs though.
