类型不匹配.期待
LexBuffer<char>但是给定aLexBuffer<byte>类型'char'与'byte'类型不匹配
这是我在使用fslex时收到的错误消息.我试过手动检查每次出现的lexbuf及其类型.它是LexBuffer<char>无处不在.但编译器仍然给我上述错误.你能否告诉我为什么会出现这种错误以及如何解决它.

let newline (lexbuf:LexBuffer<char>) = lexbuf.EndPos <- lexbuf.EndPos.NextLine
let unexpected_char (lexbuf:LexBuffer<char>) = failwith ("Unexpected character '"+(lexeme lexbuf)+"'")
}
let char = ['a'-'z' 'A'-'Z']
let digit = ['0'-'9']
let float = '-'?digit+ '.' digit+
let ident = char+ (char | digit)*

以上代码也在小提琴http://jsfiddle.net/uByVQ/中捕获.虽然,在小提琴中捕获的场景在Chrome中运行良好但在IE8中无法正常运行.我收到了错误
"不支持此命令".
我正在使用淘汰赛2.3
任何人都可以指点我的解决方案吗？
谢谢.
