haskell 错误 - 输入 '=' 上的解析错误

Question

我正在编译此代码并收到“输入 '=' 上的解析错误”错误

import System.IO  
import Data.List.Split
main = do  
   handle <- openFile "ac/abc" ReadMode  
   contents <- hGetContents handle  
   let xs = splitOneOf "; \n " contents       
   print xs   
   readStrList contents = do 
       print contents
   hClose handle

请指出错误之处

Answer 1

问题出在这几行:

readStrList contents = do 
    print contents

如果你试图定义readStrList，那么你需要把let放在前面:

let readStrList contents = do
        print contents
