Iron Python - Kein Modul mit dem Namen "os"

Habe ich versucht zu Debuggen dieses Beispiel-code, aber ich bin Probleme.

Hier ist der code:

import System
import get_events_devices
from System.Windows.Forms import *
from System.ComponentModel import *
from System.Drawing import *
from clr import *
clr.AddReference("IronPython") 

class Check: # namespace

    class Form1(System.Windows.Forms.Form):
        """type(_label1) == System.Windows.Forms.Label, type(_button1) == System.Windows.Forms.Button"""
        __slots__ = ['_label1', '_button1']
        def __init__(self):

            self.InitializeComponent()

        @accepts(Self(), bool)
        @returns(None)
        def Dispose(self, disposing):

            super(type(self), self).Dispose(disposing)

        @returns(None)
        def InitializeComponent(self):
            self._button1 = System.Windows.Forms.Button()
            self._label1 = System.Windows.Forms.Label()
            self.SuspendLayout()
            # 
            # button1
            # 
            self._button1.Location = System.Drawing.Point(58, 61)
            self._button1.Name = 'button1'
            self._button1.Size = System.Drawing.Size(75, 23)
            self._button1.TabIndex = 0
            self._button1.Text = 'Click'
            self._button1.UseVisualStyleBackColor = True
            self._button1.Click += self._button1_Click
            # 
            # label1
            # 
            self._label1.AutoSize = True
            self._label1.Location = System.Drawing.Point(190, 70)
            self._label1.Name = 'label1'
            self._label1.Size = System.Drawing.Size(0, 13)
            self._label1.TabIndex = 1
            # 
            # Form1
            # 
            self.ClientSize = System.Drawing.Size(292, 273)
            self.Controls.Add(self._label1)
            self.Controls.Add(self._button1)
            self.Name = 'Form1'
            self.Text = 'Form1'
            self.ResumeLayout(False)
            self.PerformLayout()

        @accepts(Self(), System.Object, System.EventArgs)
        @returns(None)
        def _button1_Click(self, sender, e):

            # Snippet Statement
            pass
            # End Snippet Statement
            self._label1.Text = 'mohsin'
            get_events_devices.units()

Habe ich gerade Hinzugefügt optparse.py, get_events_devices.py und Eisen python.dll.

Von wo bekomme ich ironpython_module.dll wie ich schon installieren, Iron Python bin ich nicht immer diese .dll?

Irgendwelche Ideen?
