無法導入的SimPy

Question

我是新來的simpy我用的easy_install安裝的SimPy模塊，然後在命令行中，我只是試圖from SimPy.Simulation import *上，但我得到以下錯誤

Python 2.6.7 (r267:88850, Aug 22 2011, 14:13:38) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin 
Type "help", "copyright", "credits" or "license" for more information. 
>>> from SymPy.Simulation import * 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: No module named SymPy.Simulation 

我用easy_install的安裝包，我有simplejson安裝沒有任何問題，當我導入simplejson我沒有得到上述錯誤。我做了一個更新和easy_install的成功更新SymPy模塊但我仍然不能導入的SimPy模塊

[/Library/Python/2.6/site-packages]$easy_install -U SimPy

Best match: SimPy 2.2 
Processing SimPy-2.2-py2.6.egg 
SimPy 2.2 is already the active version in easy-install.pth 

Using /Library/Python/2.6/site-packages/SimPy-2.2-py2.6.egg

我還檢查easy-install.pth文件，看起來一切都已經正確添加。

[/Library/Python/2.6/site-packages]$more easy-install.pth 
import sys; sys.__plen = len(sys.path) 
./simplejson-2.1.3-py2.6.egg 
./SimPy-2.2-py2.6.egg 
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) 

這將是偉大的，如果我能得到任何幫助。

Best; NH
