Ironpython和C#/VS 2010调试错误“未命名模块"尝试运行时选择 [英] Ironpython and C#/ VS 2010 debug error "No module named" optparse when trying to run

问题描述

大家好，
我正在尝试从C#表单应用程序中调用python脚本中的方法.我已经安装了IronPython 2.7，并且正在使用Visual Studio2010.(仅供参考，我尝试了一个简单版本，没有从脚本中导入任何内容，并且可以正常工作，我能够调用该方法)
该应用程序编译得很好，但是当我尝试运行它时，出现如下IronPyhton运行时错误:没有名为optparse的模块.这是我从python脚本文件导入的模块.似乎某处缺少python dll或错误的dll，因为如果我注释掉导入optparse行，则错误将移至下一个模块，即"os"模块.如果我注释掉该行，则错误将移至下一个导入，依此类推，我什至尝试重新排列导入模块的顺序.
我在VS项目中添加了对ipy，ironpython，ironpython.module和几个Microsoft建议的DLL的引用，例如Microsoft.Dynamic.
无济于事.可能有路径问题吗?我可以引用错误的DLL吗?
我在C:\ WINDOWS \ Microsoft.NET \ assembly \ GAC_MSIL下找到了这些DLL
所以这是它们被引用的地方.

其他人以前有类似的问题吗?

这是我包含在表单文件中的内容:

Hi all,
I am trying to make calls to methods in a python script from within my C# form app. I have installed IronPython 2.7, and I am using visual studio 2010. (FYI, I tried a simple version of this with no imports from my script, and it worked, I was able to make calls to the method)
The application compiles just fine, however when I try to run it, I get a IronPyhton runtime error like this: No module named optparse. This is a module I am importing from my python script file. It appears that there is a missing python dll somewhere, or the wrong dlls, because if I comment out the import optparse line, then the error moves to the next module which is the "os" module. If I comment out that line, the error moves to the next import, and so on,,,, I even tried re-arranging the order of the imported modules.
I have added references in my VS project to the ipy, ironpython, ironpython.module, and several Microsoft suggested DLLs, like Microsoft.Dynamic.
To no avail. Could there be a path issue? Could I be referencing the wrong DLLs?
I found these DLLs under the C:\WINDOWS\Microsoft.NET\assembly\GAC_MSIL
so this is where they are referenced to.

Anybody else have a similar issue like this before?

Here is what I am including in my form file:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using IronPython.Hosting;
using IronPython.Modules;
using IronPython.Runtime;
using System.IO;

这是我实现此功能的一小段代码，

Here is the little snippet of code where I implement this,

public Form1()
{
    InitializeComponent();

    var ipy = Python.CreateRuntime();
    try
    {
        dynamic logfile = ipy.UseFile("logparser.py");
    }
    catch (FileNotFoundException)<pre>
    {
        MessageBox.Show("unable to open logparser.py");

    }
 }

这是我要在脚本中导入的模块:

And here are the modules I am importing in my script:

import System
import os
from datetime import datetime, timedelta
import sys
import re
import thread 
import time
from optparse import OptionParser

推荐答案

我遇到了类似的问题，并找到了一种解决方法，即将带有导入模块的目录附加到路径中.
即

I had a similar issue and found a workaround by putting appending the directory with the imported module to the path.

i.e.

sys.path.append(r''c:\python\mylibrary'')

即使目录与主脚本文件所在的目录相同，我也必须这样做.

我还发现，如果我将带有导入模块的文件复制到正在加载并运行脚本的C#程序的工作目录中，则问题就消失了.

但是，我不太喜欢这两种解决方案，并且仍在寻找更好的解决方案.

I had to do this even if the directory was the same directory that the main script file lived in.

I also found that the issue went away if I copied the the file with the imported module to the working directory of the C# program that is loading and running the script.

I don''t like either solution particularly well, however, and am still trying to find a better one.
