julia - 安装后在 Julia 1.3.1 中添加包时出错

Question

我是 Julia 的新手。我已经在我的 Mac 上成功安装了最新的 Julia 1.3.1 版本。安装后，我试图添加几个包，即 StatsBase.jl 和 DataFrames.jl。它向我抛出以下错误。我尝试清理 .julia 文件夹并重新安装。没有任何帮助。

julia> using Pkg

julia> Pkg.add("StatsBase.jl")
   Cloning default registries into `~/.julia`
   Cloning registry from "https://github.com/JuliaRegistries/General.git"
     Added registry `General` to `~/.julia/registries/General`
ERROR: The following package names could not be resolved:
 * StatsBase.jl (not found in project, manifest or registry)

引用包时不要包含 .jl 扩展名。正确的命令是 Pkg.add("StatsBase")。
