宝塔面板Centos7环境下如何使Python2与Python3共存

青山 2021-11-2314:09:12评论567字

最近在研究一个爬虫应用，需要用到Python3，由于目前我的服务器是Centos7系统，默认装的Python2，为了不冲突服务器内的其他应用，想要看看可以让Python2与Python3共存，在网上搜寻了相关教程，发现有很多教程了，而且很简单，下面自己也备份一份。

下载python3安装包并解压

  1. wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz
  2. tar -xzvf Python-3.7.2.tgz

编译安装包

进入解压，编译安装包，指定安装路径，并执行安装命令

  1. cd Python-3.7.2
  2. ./configure --prefix=/usr/local/python37 #注意：prefix参数用于指定将Python安装在新目录，防止覆盖系统默认安装的python
  3. make && make install

建立软链接

  1. ln -s /usr/local/python37/bin/python3.7 /usr/bin/python3
  2. ln -s /usr/local/python37/bin/pip3 /usr/bin/pip3

输入python3检查状态

检查安装情况，按Ctrl+z或者输入exit()退出。

到这里，我们就已经实现了Python2与Python3共存，希望对有需要的朋友有所帮助。
