Fabric ImportError:无法使用Python 2.7导入名称“isMappingType”

Question

我正试着让Fab在本地运行。为什么Fab要安装到/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5？系统Python版本为2.7.10，确认如下：

Toms-MBP:~ tom$ which python
/usr/local/bin/python
Toms-MBP:~ tom$ python --version
Python 2.7.10
Toms-MBP:~ tom$ head -1 `which fab`
#!/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5
Toms-MBP:~ tom$ fab
Traceback (most recent call last):

    from operator import isMappingType
ImportError: cannot import name 'isMappingType'
