python 2.7无法导入地理编码器库

win32上的Python 2.7.10。windows 8.1

https://pypi.python.org/pypi/geocoder/1.8.0

>>> import geocoder

我以为只要安装一个decorator库就能解决这个问题,但这个库已经安装好了

C:\Python27\ArcGIS10.4\Scripts>pip install decorator
Requirement already satisfied: decorator in c:\python27\arcgis10.4\lib\site-packages

C:\Users\rizagha>python --version
Python 2.7.10

让这件事变得复杂的是,我通过arcgis安装了32位和64位python。。。
