Install PIP under multiple versions of Python

The day before yesterday installed in CentOS python2.7.12 and python3.5.2, today to install two versions of PIP, from the official download get-pip.py, using Python get-pip.py, error, unable to install. By looking for the reason, it was finally installed.

Let me explain here:

1. Problems that arise

1), no zlib library

2), no Httpshander library

2. Solution

Before the two versions of Python are installed, two libraries Zlib-devel and openssl-devel need to be installed, and after the installation is complete, the PIP can be installed properly after the Python is compiled and installed.

To summarize, install the process:

1. Installation Library

Yum Install Zlib-devel openssl-devel-y

Install the two development libraries, if not installed, there will be no zlib and httpshander libraries after the Python installation is complete.

2. Install Python

./configure--prefix=/usr/local/python27

Make && make install

Ln-s/usr/local/python27/bin/python2.7/usr/bin/python

python3.5.2

Similar to python2.7.12, slightly different, think about it yourself

3. Install Pip

wget https://bootstrap.pypa.io/get-pip.py--no-check-certificate

Python get-pip.py

Install PIP under python3.5.2 similar to 2.7, please think about it, there is no writing.
