看它的说明是把pkg打包下载到本地，但为什么下载完后再build的时候，又跑到网上下载去了，还没完没了?

主要是为了开发用的

(v1.0) pkg> ?dev
  develop [--shared|--local] pkg[=uuid] ...

  Make a package available for development. If pkg is an existing local path that path will be recorded in the
  manifest and used. Otherwise, a full git clone of pkg at rev rev is made. The location of the clone is controlled by
  the --shared (default) and --local arguments. The --shared location defaults to ~/.julia/dev, but can be controlled
  with the JULIA_PKG_DEVDIR environment variable. When --local is given, the clone is placed in a dev folder in the
  current project. This operation is undone by free.

  Example

  pkg> develop Example
  pkg> develop Example#master
  pkg> develop Example#c37b675
  pkg> develop https://github.com/JuliaLang/Example.jl#master
  pkg> develop --local Example

build 的下载估计是缺少依赖包吧，所以会自动去下载，吧依赖包都配好了就应该能本地 build 了。
