I am using Debian GNU/Linux 7.11 (wheezy), the default python is 2.7.3 and pip is 1.1 (which I have updated to 9.x). I installed python 3.6 to run some scripts, this error pops out,
Traceback (most recent call last):
File "place_fixed2_debugged.py", line 2, in <module>
ModuleNotFoundError: No module named 'requests'
so I tried
pip install requests, and it shows it is already installed, then I tried to install request module manually, I downloaded requests-2.18.4 and run
python3 setup.py, this error shows up,
File "setup.py", line 9, in <module>
from setuptools import setup
ModuleNotFoundError: No module named 'setuptools'
Then I tried
apt-get install python3-setuptools it shows also installed python3-setuptools is already installed as well.
I think the problem here is, pip and apt are installing all python related packages under a path links to the default python2.7, both requests module and setuptool are not linked to python3.
I tried virtualenv, it requires zlib module,
pip install zlib gives
root@localhost:~/Python-3.6.0# pip install zlib

Could not find a version that satisfies the requirement zlib (from versions: )
No matching distribution found for zlib
Is there any other more manageable ways to let me just link pip to python3.6? I don't really want to setup a virtualenv, thank you!
