Install Agda on OSX El Capitan?

Question

I was trying to instal Agda on my mac, following the instructions http://wiki.portal.chalmers.se/agda/pmwiki.php?n=Main.MacOSX

But I get some problems:

1. When I typed cabal update in a Terminal window, it says Skipping download: Local and remote files match. I am not sure it means it worked or not.

2. I can't find my .bash_profile file, so I don't know how to update my PATH variable .

3. If I tried just skipping the first two steps above, typing cabal install happy alex directly, and it says the following:

The exception was: ExitFailure 1 happy-1.19.5 failed during the building phase. The exception was: ExitFailure 1 

   I think this means something failed, but I don't know what to do. Help please.

EDIT :

4. If I type cabal install agda directly, it gives me the following error:

Answer 1

I would try building Agda with stack.

1. Download stack for OSX using these instructions

2. Run:

    stack setup stack install Agda 

Both steps might take a while. Watch the output to see where stack places the Agda programs - it probably will be something like ~/.local/bin

Update

Some explanation of the $PATH environment variable and how to set it:

Answer 2

在无数次失败之后，我只是卸载了旧版本的Haskell并重新安装，然后http://wiki.portal.chalmers.se/agda/pmwiki.php?n=Main.MacOSX方法运行得很好...
