【问题描述】：

我正在运行 Ubuntu 18.04.2 LTS：

user@vmubu01:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.2 LTS
Release:    18.04
Codename:   bionic

我无法使用“apt-get install”命令安装 python3-tk，如下所示：

我也无法使用 pip 安装它，请参阅下面的错误：

user@vmubu01:~$ pip3.6 install python3-tk
Collecting python3-tk

如果我尝试运行“apt --fix-broken install”命令，我会得到：

请多指教

【问题讨论】：

帮我个忙，检查/usr/lib/python3.6/tkinter 是否已经存在。它说它在安装时试图覆盖它。
也可以试试sudo apt-get install python3.6-tk
@Column01 是的，/usr/lib/python3.6/tkinter 存在，如果我运行 sudo apt-get install python3.6-tk，我会得到完全相同的错误。
这意味着 Tkinter 已经安装。尝试导入并使用它，但确保脚本使用正确的环境
@Column01 /usr/bin/python3.6 /home/user/Development/tturtle.py Traceback (most recent call last): File "/usr/lib/python3.6/tkinter/__init__.py", line 37, in <module> import _tkinter ModuleNotFoundError: No module named '_tkinter'

【解决方案1】：

不确定这个解决方案是否适合所有情况，但这里有一个对我有用。

我遇到了同样的问题（Ubuntu 16.04 除外），还尝试了@Column01 在 cmets 中写的内容：
sudo apt-get install python3.6-tk

同样的问题。但这给了我一个想法。已检查：

$ python --version
Python 3.5.2

所以解决方案很简单：

sudo apt-get install python3.5-tk
