Summary of questions about installing Python under CentOS

Python (https://www.python.org/ftp/python/)

First, tool installation

1, the installation of Python

1 tar vxf Python-2.7.13. tgz2 cd Python-2.7.13. tgz3 ./Configure 4 make && make install

2, Installation Setuptools

1 tar vxf setuptools-21.0. 0.tar.gz2 cd setuptools-21.0. 03 python setup.py Install

3. Install Pip

1 tar vxf pip-8.1.1. tar.gz2 cd pip-8.1.13 python setup.py install

Second, problem solving

1. Problem: Configure:error:no acceptable C compiler found in $PATH

1 yum-y install GCC

2. Problem: Yum error occurred: No module named Yum
Workaround: Because the Yum command is incompatible with python2.7, the/usr/bin/yum file needs to be modified to change the first line from "#!/usr/bin/python" to "#!/usr/bin/python2.6"

3. Question: "Compression requires the (missing) zlib module"
Solve:

1 Yum Install zlib 2 Yum install Zlib-devel

After the download succeeds, go to the python2.7 directory and re-execute

1  Make 2 make install

The previously executed soft connection still takes effect

Then go to the Setuptool directory and reinstall

1 python setup.py install

4. Problem: Pip use error importerror:cannot import name Httpshandle
Workaround: The reason is that the Openssl,openssl-devel two packages are not installed correctly. Use down the command to install:

1 Yum install openssl-y2 yum install openssl-devel-y

After the installation is complete, reinstall [Python] (Http://lib.csdn.net/base/python):

1 cd python2.72 ./Configure3 make install

Install PIP again normally.
