This article mainly introduces the process of CentOS7 source code compilation and installation of Python3.9. In daily operation, I believe that many people have doubts about the process of CentOS7 source code compilation and installation of Python3.9. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "CentOS7 source code compilation and installation of Python3.9". Next, please follow the editor to study!

Brief introduction

The default version of Python on CentOS7 is python2, and if you need Python3, you need to install a third-party source, or install it using source code.

Install compilation tools and dependency packages

Yum-y install wget xz tar gcc make tk-devel sqlite-devel zlib-devel readline-devel openssl-devel curl-devel tk-devel gdbm-devel xz-devel bzip2-devel

download

Download the source code package directly from the official website

Wget-t 100-c https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz

Compilation and installation

Tar zxvf Python-3.9.1.tgz cd Python-3.9.1. / configure-enable-optimizations-prefix=/opt/python39 make make install

Use

The time used to prevent the environment from interacting with each other can be isolated using a virtual environment.

/ opt/python39/bin/python-m pip install virtualenv cd / opt/ / opt/python39/bin/python-m virtualenv python3/ opt/python3/bin/python-m pip install pymysql

When in use, call / opt/python3/bin/python, if different applications can create different virtual environments, it will not cause package conflicts.

At this point, on the "CentOS7 source code compilation and installation of Python3.9 process" on the end of the study, I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
