Question

我在Linux mint 18.3上使用3个版本的python

explain analyze select * from my_table where label = '123456';

                                                     QUERY PLAN                                                     
--------------------------------------------------------------------------------------------------------------------
 Index Scan using my_index on my_table  (cost=0.42..8.44 rows=1 width=10) (actual time=0.288..0.290 rows=1 loops=1)
   Index Cond: (label = '123456'::text)
 Planning time: 80.753 ms
 Execution time: 0.476 ms
(4 rows)

我可以用python2.7和tkinter python3.6导入Tkinter ......

silvock@silvock-TM1701 ~ $ python -V
Python 2.7.12
silvock@silvock-TM1701 ~ $ python3 -V
Python 3.5.2
silvock@silvock-TM1701 ~ $ python3.6 -V
Python 3.6.5

...但是使用python3（python 3.5）它不起作用。

silvock@silvock-TM1701 ~ $ python 
Python 2.7.12 (default, Dec  4 2017, 14:50:18) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>> 


silvock@silvock-TM1701 ~ $ python3.6
Python 3.6.5 (default, May  3 2018, 10:08:28) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>>

而已经安装了python3-tk：

silvock@silvock-TM1701 ~ $ python3
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
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:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.5/tkinter/__init__.py", line 38, in <module>
    raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package
>>> quit()

我想使用python3.5进行工作。

我徒劳无功

silvock@silvock-TM1701 ~ $ sudo apt-get install python3-tk
