学Python配置完了VScode，在安装easygui后遇到了一些问题。

代码如下：

import easygui
easygui.msgbox("Hello world.")

Ctrl+Shift+B，运行报错，报错如下：

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

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/hongludianxue/.local/lib/python3.5/site-packages/easygui/boxes/utils.py", line 29, in 
    import tkinter as tk  # python3
  File "/usr/lib/python3.5/tkinter/__init__.py", line 38, in 
    raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package

During handling of the above exception, another exception occurred:

  File "/home/hongludianxue/.local/lib/python3.5/site-packages/easygui/boxes/utils.py", line 36, in 
    import Tkinter as tk  # python2
ImportError: No module named 'Tkinter'

During handling of the above exception, another exception occurred:

    from . import utils as ut
  File "/home/hongludianxue/.local/lib/python3.5/site-packages/easygui/boxes/utils.py", line 43, in 
    raise ImportError("Unable to find tkinter package.")
ImportError: Unable to find tkinter package.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/hongludianxue/Documents/Python file/0x00.py", line 1, in 
    import easygui
  File "/home/hongludianxue/.local/lib/python3.5/site-packages/easygui/__init__.py", line 34, in 
    from .boxes.button_box import buttonbox
  File "/home/hongludianxue/.local/lib/python3.5/site-packages/easygui/boxes/button_box.py", line 18, in 
    import global_state
ImportError: No module named 'global_state'

看到ImportError: No module named '_tkinter'才知道，原来是没有tkinter这个模块。

在终端里面安装上tkinter：

sudo apt-get install python3-tk

完成之后在运行之前的Python代码，发现已经成功运行啦。
