Fixed issue: setuptools keeps complaining about python2 #178

Closed samduy closed 4 years ago

samduy commented 4 years ago

Description:

On the system that has both python2 and python3 that have been running well together (like Kali Linux), it's unable to complete even the first step in setting up ctf-tools environment. When execute bin/manage-tools setup it always fails where setuptools complain about python2 (see details below).

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Analysis

The reason of this complaining is ctf-tools using the same script for both python2 and python3 environment and then forcing python2's pip to install setuptools even though setuptools can be (and is recommended) to installed with python3.

Solution

The fix is specifically call pip for python3 by python3 -m pip instead of just pip as currently used for both bin/ctf-tools-pip and bin/ctf-tools-pip3.

The Fix

Remove the symlink of ctf-tools-pip3 (that pointed to ctf-tools-pip), copy the content from ctf-tools-pip and replace exec pip by exec python3 -m pip
