Python错误：没有名为RuntimeError的模块

Question

Im trying to figured out this problem. Yesterday I installed PyScripter and since then, scripts doesnt work. When I run any script (in PyScripter or IDLE) and trying to "import arcpy", it gets this error:

import arcpy

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import arcpy
  File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\__init__.py", line 17, in <module>
    from geoprocessing import gp
  File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\geoprocessing\__init__.py", line 14, in <module>
    from _base import *
  File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\geoprocessing\_base.py", line 14, in <module>
    import arcgisscripting
  File "C:\Python26\ArcGIS10.0\lib\arcgisscripting.py", line 81, in <module>
    from RuntimeError import RuntimeError
ImportError: No module named RuntimeError

Have somebody any suggestion how to fix it?

Thanks to all very much!

Sounds like the module is not installed properly (or at all). To verify, do the following:

1. open a shell and start the python shell by typing python (If this doesn't display an error, check that python is added to your system path or if it is even installed at all. But if you've used Python on said machine maybe system path issue)

2. enter the commmand help('modules')

3. review the list of modules that's returned to see whether arcpy is included if not, then you may have to reinstall the module
