ruby - 第 1 行中的非法引用。 (CSV::MalformedCSVError)

Question

当我尝试读取使用 Selenium WebDriver 下载的 CSV 文件时，我在第 1 行收到了一个Illegal quoting. (CSV::MalformedCSVError)。

CSV.foreach( "foo.csv" ) do |row|
  # anger :(
end

但是当我复制内容并将其粘贴到一个新文件中并再次保存时，它工作得很好:

CSV.foreach( "bar.csv" ) do |row|
  # works fine
end

这是有问题的 CSV 的前 5 行，以防有帮助...

我一直无法找到或想出一种方法来正确读取我的原始、selenium 下载的 CSV。任何人遇到这个问题或对我的数据可能有什么问题有任何想法，或者我如何以编程方式解决这个问题？

谢谢!

很可能你的文件开头有一个字节序标记U+FEFF。当您再次复制和粘贴时，您可能会丢失它。

正确的解决方法是:

CSV.foreach("foo.csv", "r:bom|utf-8") { ... }
