安装后在Julia 1.3.1中添加程序包时出错

我是朱莉娅的新手。我已在Mac上成功安装了最新的Julia 1.3.1版本。安装后，我尝试添加两个包，即StatsBase.jl和DataFrames.jl。这让我犯了以下错误。我已尝试清理.julia文件夹并重新安装。没有任何帮助

julia> using Pkg

julia> Pkg.add("StatsBase.jl")

参考软件包时，不要包括

.jl

扩展名。正确的命令是

Pkg.add（“StatsBase”）

或更简短的

Pkg“addstatsbase”

谢谢！答案奏效了。@PrzemyslawSzufel的缩写形式也适用！
