现在Feather包已经支持1.0了, 但是我安装老是出错:

具体报错如下

 Pkg.add("Feather")
ERROR: The following package names could not be resolved:
 * Feather (not found in project, manifest or registry)
Please specify by known `name=uuid`.

解决方法

删除registries文件夹, 建议删除前做一下备份

Windows

C:\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries

或者:

C:\Users\Name\AppData\Local\JuliaPro-1.0.1.1\pkgs-1.0.1.1\registries

提示: 实在找不到, 用everything软件找一下这个文件夹, 删除或者改成其他名称, 然后再运行代码

Linux

 ~/.julia/registries

或者:

/opt/Julia/JuliaPro-1.0.1.1/JuliaPro/pkgs-1.0.1.1/registries

删除之后, 重新运行

julia> using RData
