当我在python空闲中导入arcpy时，我收到一个错误

Question

当我键入import arcpy时出现此错误

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    from arcpy import da
  File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\__init__.py", line 21, in <module>
    from arcpy.geoprocessing import gp

    env = GPEnvironments(gp)

    return GPEnvironment(geoprocessor)

    envset = (set(env for env in self._gp.listEnvironments()))
RuntimeError: NotInitialized

我该怎么办？ 我也需要在日食中使用arcpy，我不能！
