在CentOS下安装idle-python2.7

Question

I am looking to install an IDE for Python. I am working on a VM with a Python version of 2.7.5, and under CentOS7.

I am trying to install it on the command line under my terminal. For now I only found commands with "apt-get" ..

When I try yum install idle-python2.7 , I get this:

No python3-tools package available.

And when I try "yum install python-tools", I get this as an error:

[root@nexus-chat1 ~]# idle
Traceback (most recent call last):
  File "/usr/bin/idle", line 5, in <module>
    main()
  File "/usr/lib64/python2.7/idlelib/PyShell.py", line 1507, in main
    root = Tk(className="Idle")
  File "/usr/lib64/python2.7/lib-tk/Tkinter.py", line 1745, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

Or do you know of other IDEs for Python that I could easily install?

Answer 1

You are right that idle is provided by package python-tools on CentOS 7.

And based on your description, it seems that the package is installed properly. You can verify that by running:

# rpm -q python-tools
python-tools-2.7.5-58.el7.x86_64

The error you see when you try to run it is caused by the fact that idle is a gui application, and you are likely connected via ssh without X forwarding enabled.
