我的计算机中安装了Julia、Juno和Atom。它运行良好。我正试图基于以下链接使用Pkg.clone((：https://github.com/uoa-ems-research/JEMSS.jl我收到如下错误消息：
julia> Pkg.clone("https://github.com/samridler/JEMSS.jl.git")

因此，看起来我需要清除/删除位于..的文件/用户/jack/.julia/dev/JEMSS，然后再试一次，对吗？也许是因为我不止一次克隆了这个文件？有我可以使用的命令吗？
这是因为Stats包与您的julia版本不兼容，根据消息，它看起来是0.7或1.0。只需rm包裹。现在，您必须手动加载JuliaStats包。
