我已经安装了matplotlib
Python,安装pip
过程没有出现任何错误。但是当我尝试导入它时,出现了这个错误:
import matplotlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/rishabh/.local/lib/python2.7/site-packages/matplotlib/__init__.py", line 131, in <module>
from matplotlib.rcsetup import defaultParams, validate_backend, cycler
File "/home/rishabh/.local/lib/python2.7/site-packages/matplotlib/rcsetup.py", line 29, in <module>
from matplotlib.fontconfig_pattern import parse_fontconfig_pattern

from backports.functools_lru_cache import lru_cache
ImportError: No module named functools_lru_cache
答案1
试试这个,我今天早上遇到了同样的问题
sudo apt-get install python-matplotlib
我安装了几个模块后,稍后也使用了 python3.7。我跑了。
pip3 install matplotlib
我现在可以导入 matplotlib。
答案2
首先卸载
pip uninstall backports.functools_lru_cache
然后重新安装
pip install backports.functools_lru_cache
就像描述的一样在这个答案中。
