安装 Python 3.5.2，但安装 Python 2.6 的 pip

Question

VPS-server was a version Python 2.6, I installed version Python 3.5.2. When I try to install some packages with help pip , I got errors.

During installation packages:

DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

Versions:

# Python -V
# Python 3.5.2

# pip -V
# pip 8.1.2 from /usr/lib/python2.6/site-packages/pip-8.1.2-py2.6.egg (python 2.6)

# cat /etc/*-release
# CentOS release 6.8 (Final)

How to change path to pip from python 3.5 ?

Answer 1

if you haven't pip in server you can use get-pip file:

after install python usually installed pip and you can run by pip3 command

for example you can use:

pip3 install netaddr

Answer 2

Upgrading pip manually solved this issue for me once. Update pip Documentation

pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4 downloaded from python.org, but you'll need to upgrade pip.

On Linux or OS X:

pip install -U pip

On Windows [5]:

python -m pip install -U pip
