can't manage to install correctly, test fail on my computer

[bcameron43]

I cannot use any of the Taro functions.

Pkg.test("Taro")
INFO: No packages to install, update or remove
ERROR: Taro did not provide a test/runtests.jl file

That is really strange. Taro does indeed provide a test/runtests.jl file, as you can see here: https://github.com/aviks/Taro.jl/blob/master/test/runtests.jl

What version of Taro do you see when you do a Pkg.status()? What happens when you do a using Taro in the REPL? Which OS are you using?

[bcameron43]

Using OS X 10.10.5, Taro v0.2.0

">using Taro" does not cause an error, but when I do "Taro.init()" it fails.

[aviks]

What error do you see when you run Taro.init()

[bcameron43]

init() not defined

[bcameron43]

Also, I now realise I have to rebuild each time I launch julia to avoid an error when 'using Taro'

See below

OK, so right there is your issue: ERROR: Cannot find java library libjvm.dylib ....

Taro (and its underlying JavaCall package) cannot find the JVM to load. It looks like you do not have a 1.7 version of the JDK installed in your machine. JavaCall, and hence Taro does not work with 1.6.

Please see http://aviks.github.io/JavaCall.jl/index.html for documentation relating to JavaCall.

PS. I will look at making the init() error better.

I have a similar problem on Windows:

julia> using Taro
ERROR: LoadError: LoadError: InitError: Cannot find java library jvm.dll
Search Path:
   C:\Program Files\Julia-0.4.5

I never used JavaCall.jl, but noticed it was installed when I Pkg.add'ed Taro. It seems the installation instructions assume you have a working JavaCall.

This package looks interesting, but not enough to get me to want to fiddle with getting a proper JVM installed at this time. Any chance to make the installation smoother?

Just tried to install/use Taro on 0.62 on a Mac and got a seg fault:
