Linux CentOS服务器安装Python3.8环境
在Linux CentOS服务器中安装Python3.8环境,源码对于脚本编写、编译大数据框架、源码vc 获取网页源码数据分析和开源框架运行具有广泛用途。编译以下是源码买菜送菜app 源码详细的安装步骤:
### 安装前准备
在开始安装Python3.8之前,请确保您的编译联联生活源码系统中已安装以下开发工具:
<yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel gcc
接下来,进入Python3.8源码目录,源码并执行编译安装:
#cd python3.8/
./configure --prefix=/usr/local/python3
make && make install
### 配置环境变量
为了使Python3.8能够被系统识别,编译编辑/etc/profile文件以添加环境变量配置:
PYTHON_HOME=/usr/local/python3
PATH=$PATH:$JAVA_HOME/bin:$PYTHON_HOME/bin
export PATH JAVA_HOME CLASSPATH PYTHON_HOME
完成配置后,源码通过运行以下命令使环境变量配置立即生效:
source /etc/profile
至此,编译您已成功安装并配置了Python3.8环境。源码
### 设置默认Python版本
为了将Python3.8设为默认版本,编译可以备份旧的源码熊猫变声器源码Python2:
mv /usr/bin/python /usr/bin/python2.back
然后创建指向Python3的软链接:
ln -s /usr/local/python3/bin/python3 /usr/bin/python
若需要同时支持Python2和Python3,可以单独为Python3创建软链接:
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
这样,编译您便可以在不干扰现有Python2环境的源码吃瓜社区源码情况下,直接使用Python3进行工作。
