Question

我最近将我的Ubuntu更新为18.04，现在使用Python（2.7）时我无法再导入matplotlib。导入时出错：

>>> import matplotlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "~/.local/lib/python2.7/site-packages/matplotlib/__init__.py", line 131, in <module>
from matplotlib.rcsetup import defaultParams, validate_backend, cycler
File "~/.local/lib/python2.7/site-packages/matplotlib/rcsetup.py", line 29, in <module>
from matplotlib.fontconfig_pattern import parse_fontconfig_pattern
File "~/.local/lib/python2.7/site-packages/matplotlib/fontconfig_pattern.py", line 28, in <module>
from backports.functools_lru_cache import lru_cache
ImportError: No module named functools_lru_cache

我通过

安装了matplotlib

pip install --user matplotlib

与matplotlib一样，functools_lru_cache-module安装在

中

~/.local/lib/python2.7/site-packages

我在这里缺少什么？

我尝试卸载并重新安装“functools_lru_cache”模块，如下所示： python 2.7 functools_lru_cache does not import although installed 但这没有帮助。还是一样的错误。

通过pip卸载matplotlib并安装旧版本（2.0.2）为我解决了这个问题。请参阅：https://stackoverflow.com/a/49335954/1627966

由于缺少“functools_lru_cache”，无法在更新到Ubuntu 18.04后导入matplotlib
