使用Mono运行F#代码

Question

我安装了F#2.0.0,并使用mono 2.8.

let rec fib n =
    match n with
    | 1 | 2 -> 1
    | n -> fib(n-1) + fib(n-2)

let n = 40
let x = fib(n)
printfn "%d" x

我用fsc.exe编译了这段代码来获取fib.exe.使用mono fib.exe运行它会给我这个错误.

mono fact.exe 
Could not load file or assembly 'FSharp.Core, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Unhandled Exception: System.TypeLoadException: Could not load type 
'.$Factorial' from assembly 'factorial, Version=0.0.0.0,
 Culture=neutral, PublicKeyToken=null'.

可能有什么问题？

添加

sudo gacutil -i FSharp.Core.dll 

解决了这个问题.

F#程序集(如FSharp.Core.dll)可能只安装到.Net GAC.您需要将它们安装到Mono的GAC(Mono的gacutil.exe),或将程序集复制到与可执行文件相同的目录中.
