安装python3-tk包出错

Question

通过键入以下命令，我在安装python3-tk时收到以下错误：

apt-get install python3-tk

Need to get 34.4 kB of archives.
After this operation, 150 kB of additional disk space will be used.
WARNING: The following packages cannot be authenticated!
  python3-tk
Install these packages without verification? [y/N] y
Err http://us.archive.ubuntu.com/ubuntu/ wily/main python3-tk amd64 3.4.3-4
  404  Not Found [IP: 91.189.91.26 80]
E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/p/python3-stdlib-extensions/python3-tk_3.4.3-4_amd64.deb  404  Not Found [IP: 91.189.91.26 80]

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
I tried to run apt-get update and tried with --fix-missing but of no use. Can anybody help me figure out the way to solve this or provide alternate method to download tkinter for python3 ?

Answer 1

如果您使用的是Ubuntu，请先尝试添加deadsnakes：

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

然后，根据similar question的回答，这取决于您使用的python版本和您的项目配置：

为Python3.x.x安装tkinter：

sudo apt-get install python3-tk

对于Python 3.6虚拟环境，使用Python 3.5作为“系统”python：

sudo apt-get install python3.6-tk

“一般来说，如果使用的虚拟环境的python版本不同于基础机器的版本，则必须为虚拟环境中使用的python版本安装tk”：

sudo apt install python3.x-tk

‘其中3.x将与虚拟环境的版本相匹配。’

Answer 2

您不需要单独安装tkinter。只需使用from tkinter import *即可
