Question

我最近开始研究朱莉娅的并行处理，我遇到了一个我不太懂的问题。

用julia -p 4执行Julia之后我想在所有进程中加载Distributions模块，我想定义一个依赖于Distributions的Type。

以下内容显然可以正常使用：

 @everywhere using Distributions

 type TypeDistrib{T <: Float64}
      d::Distributions.Normal{T}
 end

如果我编写与模块完全相同的代码，那么它就不会：

 module test

    @everywhere using Distributions

    type TypeDistrib{T <: Float64}
         d::Distributions.Normal{T}
    end

    export TypeDistrib
 end

以上显示以下错误消息：

错误：LoadError：UndefVarError：未定义的分布在include_from_node1（:: String）at ./loading.jl:488 在include_from_node1（:: String）/Applications/Julia-0.5.app/Contents/Resources/julia/lib/julia/sys.dylib：？加载/***/test.jl时，从第4行开始的表达式

请你澄清一下我在这里做得不好吗？

注意：我用***替换了错误消息中的完整路径，因为它很混乱。

也许

test

是什么意思。

并行处理：@everywhere，发行版和类型
