python3 安装 matplotlib 出现的错误

在Ubuntu16.04系统下

python3

在安装时，采用sudo pip3 install matplotlib

python3

>>import matplotlib.pyplot as plt

出现错误：

Traceback (most recent call last):
  File "/usr/lib/python3.5/tkinter/__init__.py", line 36, in <module>
    import _tkinter
ImportError: No module named '_tkinter'


During handling of the above exception, another exception occurred:

  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/matplotlib/pyplot.py", line 116, in <module>

    raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package

解决方案:

由上面错误可知，缺少tkinter

安装 tkinter

sudo apt-get install python3-tk

解决！
