How to import a package at startup in Julia REPL, if available

Question

I would like to import the package anytime when I run REPL. Inclusion ~/.juliarc.jlat the beginning:

if isinteractive()
    using Humanize
end

But if I run juliaon a machine without this package, REPL does not start.

So, I tried the following:

if isinteractive()
    try
        using Humanize
    catch
    end
end

but due to the rules of definition Julia is now Humanizenot even available in the global namespace.

What is the best solution?

Try the following: a hack bit until something better appears in the database:

humanize_exists = isdir(Pkg.dir("Humanize"))
if humanize_exists && isinteractive(); using Humanize; end
