Julia Can'；t读取csv文件："；没有与解析器匹配的方法。选项“；,julia,Julia,读取csv文件应该是直截了当的，对吗？但当我这么做的时候： df = CSV.read("sources/diamonds2.csv") 我收到一些糟糕的错误消息： ERROR: MethodError: no method matching Parsers.Options(::Missing, ::UInt8, ::UInt8, ::UInt8, ::UInt8, ::UInt8, ::UInt8, ::UInt8, ::Nothing, ::Nothing, ::Nothing, ::Bo

解释 CSV.jl版本已通过

read

重新发布（请参阅）

无论是更新到

0.6.2

，还是降级到

0.5.26

（当您无法更新时），都应该非常有效

不是100%确定，但这看起来像是一些包不同步了-你能发布

]st-m的输出吗？好的，它可以工作。非常感谢。但是，孩子，这是一个麻烦。像读取csv文件这样简单的东西真的应该“像那样”工作。另外，我试图先只更新CSV包，但没有成功。我猜CSV
的人进行了大量的代码重新设计，结果出了问题。我自己也遇到了和你一样的问题，一段时间以来我不得不回到0.5.26。但我知道他们在加快CSV解析方面做了多么大的工作（当你真的想做的时候，这真的不是琐事）。所以，让我们希望它在某个时刻变得稳定。再次感谢你的回答。
