This article introduces the "CentOS7 installation and use of Python3 tutorial" related knowledge, in the actual case of the operation process, many people will encounter such a dilemma, and then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

Brief introduction

Python2 is installed by default on CentOS7, but now many programs need Python3 by default to run properly.

If you use the Python environment of the system, the update package may break the dependency when the system is updated.

The best way is to compile and install a Python3, and then use a virtual environment to run our Python program.

The reason why we use the virtual environment is so that the Python3 we install can be used by multiple programs, and the installation packages will not conflict with each other.

Compilation and installation

When compiling, you need to install some dependent packages

#! / bin/bash VERSION='3.10.0' yum-y install xz tar gcc make tk-devel wget sqlite-devel zlib-devel readline-devel openssl-devel curl-devel tk-devel gdbm-devel xz-devel bzip2-devel libffi-devel cd / root/ wget-c https://mirrors.huaweicloud.com/python/${VERSION}/Python-${VERSION}.tgz tar xvf Python-$ {VERSION} .tar.xz cd Python-$ {VERSION}. / configure-- prefix=/opt/python3 Make make install echo 'export PATH=/opt/python3/bin:$PATH' > > / etc/profile use test source / etc/profile python3-V to set the mirror source mkdir ~ / .pip cat > ~ / .pip/pip.conf
