python-3.x - 无法在 Ubuntu 18.04.2 LTS 上安装 python3-tk

Question

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:

user@vmubu01:~$ sudo apt-get install python3-tk

我也无法使用 pip 安装它，请参阅以下错误:

user@vmubu01:~$ pip3.6 install python3-tk
Collecting python3-tk
  ERROR: Could not find a version that satisfies the requirement python3-tk (from versions: none)
ERROR: No matching distribution found for python3-tk

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

user@vmubu01:~$ sudo apt --fix-broken install

请多多指教

Answer 1

不确定此解决方案是否适合所有情况，但这是对我有用的解决方案。

我有同样的问题(除了 Ubuntu 16.04)，也尝试了@Column01 在评论中写的:
sudo apt-get install python3.6-tk

同样的问题。但这给了我一个主意。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
