当编写一个脚本哈斯克尔，附近获得意外的标记语法错误 [英] When writing a haskell script, get syntax error near unexpected token

问题描述

当我写一个简单的脚本，并通过它来runhaskell，它工作正常，但不是当我添加家当，并尝试直接执行它。脚本是这样的：

When I write a simple script and pass it to runhaskell, it works fine, but not when I add a shebang and try executing it directly. The script is this:

#!/usr/local/bin/runhaskell

import Data.List (intercalate)

main :: IO ()
main = putStrLn $ intercalate " " $ map show [1..10]

如果我尝试 $ runhaskell count.hs Bash打印 1 2 3 4 5 6 7 8 9 10 作为预期，但如果我尝试 ./ count.hs 我收到以下错误：

If I try $ runhaskell count.hs bash prints 1 2 3 4 5 6 7 8 9 10 as expected, but if I try ./count.hs I get the following error:

./count.hs: line 3: syntax error near unexpected token `('
./count.hs: line 3: `import Data.List (intercalate)'

时对原产于bash或runhaskell这个错误？如何解决呢？

Is this error originating in bash or runhaskell? And how do I fix it?

推荐答案

请尝试使用：

#!/usr/bin/env runhaskell
...

请注意：这与OSX功能/问题，即家当间preters都要求是二进制文件。见<一href=\"http://stackoverflow.com/questions/9988125/shebang-pointing-to-script-also-having-shebang-is-effectively-ignored\">Shebang指向脚本（也有家当）被有效地忽略了解更多详情。

Note: this is a feature/issue with OSX where shebang interpreters are required to be binaries. See Shebang pointing to script (also having shebang) is effectively ignored for more details.
