所以我从FParsec示例运行下面的代码,但它似乎并不想运行。FParsec示例为什么不运行?
namespace Test
open FParsec.CharParsers
module Stuff =
let main = run pfloat "1.25E3"
let str s = pstring s
let floatBetweenBrackets = str "[" >>. pfloat .>> str "]"
的问题是最后一行 - 我得到这个错误:
Error 1 Expecting a type supporting the operator '>>.' but given a function type. You may be missing an argument to a function. C:\Users\...\Documents\Visual Studio 2013\Projects\Solution2\ConsoleApplication1\load.fs 6 42 Formatting
的代码是从这里:

如果它的事项,F#的版本,我运行是:
Microsoft (R) F# Interactive version 12.0.30110.0
我觉得'(>>。)'是在'FParsec.Primitives'模块中定义的,所以您需要打开代码进行编译。 – kvb
