Pip3无法找到/安装模块

Question

I'm trying to install packages in Python using pip3. I've definitely managed to install these packages on other systems, so I know they exist. But it's as if the pip3 repository I'm using doesn't contain then. The packages are shelve and os. The error I get is along the lines of:

    [root@host]# pip3 install shelve
Collecting shelve
  Could not find a version that satisfies the requirement shelve (from versions: )
No matching distribution found for shelve

I'm using RHEL 7 if that makes any difference.

Answer 1

The project has one release in 2011 and the release doesn't have downloadable files. Not a useable project by all accounts.

Do you mean shelve from the stdlib ? You don't need to install it, it's always available, just import it.

Answer 2

you cal also use for example for install tkinter package :

sudo apt-get install python-tk; if you have python installed

or you can use :

sudo apt-get install python3-tk; if you have python3 installed
