当我尝试导入matplotlib时出现错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/__init__.py", line 128, in <module>
  from matplotlib.rcsetup import defaultParams, validate_backend, cycler
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/rcsetup.py", line 29, in <module>

    from backports.functools_lru_cache import lru_cache
ImportError: No module named functools_lru_cache

backports本身导入正常.当我尝试手动安装functools时

sudo pip install backports.functools_lru_cache

我得到的信息

Requirement already satisfied: backports.functools_lru_cache in /usr/local/lib/python2.7/dist-packages

然而,当我尝试

import backports.functools_lru_cache

我得到的信息

ImportError: No module named functools_lru_cache

系统信息Ubuntu 16 Python 2.7.12 Pip 9.0.1
