我正在使用python 3.7.1，最近当我尝试运行matlplotlib时，它不起作用。我收到此错误：
AttributeError: module 'matplotlib' has no attribute '_get_configdir'
我尝试使用“ matplotlib.use（“ Agg”）“，但仍然出现相同的错误。
我尝试使用此命令在anacond中升级我的matlpotlib版本
pip install --upgrade matplotlib，我收到此错误。

chances 0.1.6 has requirement matplotlib==2.2.3, but you'll have matplotlib 3.1.1 which is incompatible.

有人可以指导我吗？ 我不知道该怎么办。谢谢。
