在python 2.7中没有发生pip升级

Question

I am in confusion. I have looked in other posts in regard to this problem. In terminal of conda env., when I ran

conda list

all the packages are displayed with versions. pip version is 8.0.2

When I tried

 python -m pip install --upgrade pip

The cursor move to next line and blinks for long time. I intend to update pip . The above line is suppose to upgrade pip. Am I missing something and what are possible solutions.

Answer 1

Upgrade pip:

pip install --upgrade pip

Upgrade all packages with pip:

import pip
from subprocess import call

for dist in pip.get_installed_distributions():
    call("pip install --upgrade " + dist.project_name, shell=True)
