在CentOS 7上通过源码安装Python 3.7.4

1. 安装依赖包

sudo yum install gcc openssl-devel bzip2-devel libffi-devel

2. 下载Python

wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz

3. 解压缩Python的源码压缩文件

 tar -xf Python-3.7.4.tar.xz

4. 配置、编译、安装三部曲

./configure --prefix=/opt/python #安装路径根据自己需要设置
make
make install

5. 创建软连接

cd /opt/python/bin
ln -s python3.7 python

6. 将python所在路径添加到PATH变量

sed -i 's!PATH=!PATH=/opt/python/bin:!' ~/.bash_profile
. ~/.bash_profile

7. 验证

[marlonm@centos7 bin]$ which python
/opt/python/bin/python
[marlonm@centos7 bin]$ python -V
Python 3.7.4

8. 创建virtualenv (可选，如不使用virtualenv,可略过此步)

[marlonm@centos7 ~]$ cd /opt/
[marlonm@centos7 ~]$ python -m venv env
[marlonm@centos7 opt]$ source env/bin/activate
(env) [marlonm@centos7 opt]$ which python
/opt/env/bin/python
