麻烦大家我想问一个问题 
：
更新到JuliaPro 1.0.1.1（Julia 1.0.1）之后，安装一个JuliaFEM的包时，发生了如下问题：
julia> using Pkg
julia> Pkg.add("JuliaFEM")
Updating registry at `D:\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries\JuliaPro`
Updating git-repo `https://pkg.juliacomputing.com/registry/JuliaPro`

有的库可以安装成功，有的就不行，请问一下这是为什么啊 
但是好像还是不行…
