【python】ImportError: No module named '_tkinter', please install the python3-tk package

在python3.6下运行程序报错：

File "/usr/lib/python3.6/tkinter/__init__.py", line 37, in 
    import _tkinter
ModuleNotFoundError: No module named '_tkinter'

During handling of the above exception, another exception occurred:

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

根据这个报错信息尝试安装python3-tk，无对应包。

仔细查看错误信息是与matplotlib包有关，可能是配置问题，重新安装此包：

pip uninstall matplotlib
pip install matplotlib

重新运行程序，成功！
