键错误：'kivy.garden.graph'

Question

我最近刚开始使用kivy，但是当我从kivy.garden.graph导入MeshLinePlot它会出错

 Traceback (most recent call last):
   File "<pyshell#0>", line 1, in <module>
     from kivy.garden.graph import MeshLinePlot
   File "<frozen importlib._bootstrap>", line 983, in _find_and_load
   File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked
   File "<frozen importlib._bootstrap>", line 668, in _load_unlocked
   File "<frozen importlib._bootstrap>", line 640, in _load_backward_compatible
 KeyError: 'kivy.garden.graph'

我已经使用windows安装指南安装了Kivy https://kivy.org/doc/stable/installation/installation-windows.html

Answer 1

如果没有安装matplotlib，就应该安装matplotlib

如果以上不起作用或仍然输出键错误kivy.garden.matplotlib在

您应该在命令窗口中键入以下内容

garden install matplotlib

I have already installed it you can view the picture here am using matplotlib 3.1.1 python 3.7

您需要先安装kivy garden模块：

pip install kivy-garden
