Python can'；进口是安全的运输

我正在使用python的TwitterAPI（ubuntu+pycharm）

我通过“pip安装networkx TwitterAPI”安装TwitterAPI。 我只是按照如下方式导入TwitterAPI：

from TwitterAPI import TwitterAPI

  File "/home/hanlu/PycharmProjects/cs579/a1.py", line 29, in <module>
    from TwitterAPI import TwitterAPI
  File "/home/hanlu/.local/lib/python2.7/site-packages/TwitterAPI/TwitterAPI.py", line 7, in <module>
    from requests_oauthlib import OAuth1
  File "/home/hanlu/.local/lib/python2.7/site-packages/requests_oauthlib/__init__.py", line 3, in <module>
    from .oauth2_auth import OAuth2
  File "/home/hanlu/.local/lib/python2.7/site-packages/requests_oauthlib/oauth2_auth.py", line 3, in <module>
    from oauthlib.oauth2 import is_secure_transport
ImportError: cannot import name is_secure_transport

>> python
python 2.7.7
>>import oauthlib
>>oauthlib__version__
  '0.6.3'

执行python文件时，出现如下错误：

from TwitterAPI import TwitterAPI

  File "/home/hanlu/PycharmProjects/cs579/a1.py", line 29, in <module>
    from TwitterAPI import TwitterAPI
  File "/home/hanlu/.local/lib/python2.7/site-packages/TwitterAPI/TwitterAPI.py", line 7, in <module>
    from requests_oauthlib import OAuth1
  File "/home/hanlu/.local/lib/python2.7/site-packages/requests_oauthlib/__init__.py", line 3, in <module>
    from .oauth2_auth import OAuth2
  File "/home/hanlu/.local/lib/python2.7/site-packages/requests_oauthlib/oauth2_auth.py", line 3, in <module>
    from oauthlib.oauth2 import is_secure_transport
ImportError: cannot import name is_secure_transport

>> python
python 2.7.7
>>import oauthlib
>>oauthlib__version__
  '0.6.3'

我仍然不明白，我的环境出了什么问题？

使用oauthlib-0.7.1来解决这个问题

  sudo pip install oauthlib --upgrade

---

删除旧的oauthlib包

apt-get remove python-oauthlib

并安装最新的oauthlib版本0.7.1

pip install oauthlib -U

你找到这个问题的解决办法了吗。。？？
