我在用Julia语言导入数据帧时遇到问题

我不知道怎么解决，请帮帮我

julia> using DataFrames

julia> readtable("/home/ronald/Documentos/csv/model.csv")
Error showing value of type DataFrames.DataFrame:

以及“/home/ronald/Documentos/csv/model.csv”中的内容？请检查Pkd.dir（）*“DataFrames/test/data”以查看示例.csv文件列表，您可以复制一个并修改它…您应该尝试使用Julia版本0.5（当前的稳定版本），而不是开发版本0.6。
