Install python environment

• Install python Library

  pip install -i http://pypi.douban.com/simple --trusted-host pypi.douban.com -r requirements.txt

• Install Python dependencies

  yum -y install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

• Release file:

  tar -xvzf Python-3.5.6.tgz

• Enter the directory:

  cd Python-3.5.6/

• Add configuration: (configure your own installation directory here)
  /configure --prefix=/usr/local/python

• Next, compile the source code:

  make

• Perform the installation:

  make altinstall

  We need to install Python 2.7.5 ourselves. But it is worth noting that we must not destroy the environment of the system. Because several key utility applications rely on Python 2.4.3. If the python environment of the system is replaced, many unforeseen errors will occur, leading to system reinstallation.

• Soft link
  A very important step is that we use make altinstall. If you use make install, you will see that there are two different versions of Python on the system in the / usr/bin / directory. This will lead to many problems and is not easy to deal with.

  Although we can use the commands of python3 and pip3 in this path (/ usr/local/python3.6.3/bin), or use them in any path after adding the path environment variable, we should always add "3" instead of the usual Python and pip.

  Toggle (modify default link)
  The python and pip commands we usually use are in the / usr/bin / directory, so,
  We need to make the python and pip commands here soft link to our python 3 and pip3 commands.

  There are two ways (choose 1 from 2):

  1. Manual
  2. By command
  Manual:
  1),# cd /usr/bin
  2) , MV python. Back / / back up the original Python
  3),# ln -s /usr/local/bin/python3.6 /usr/bin/python
  4),# ln -s /usr/local/bin/python3.6 /usr/bin/python3
