linux中安装python3.7

1. 安装依赖包

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

2. 下载python3.7

# 下载wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz#解压tar -xvf Python-3.7.2.tgz

3. 执行配置文件，编译安装

mkdir -p /usr/local/python3.7cd Python-3.7.2/./configure --prefix=/usr/local/python3.7 make make install

4. 建立软连接

#建立python3连接ln -s /usr/local/python3.7/bin/python3.7 /usr/bin/python3#建立pip3连接ln -s /usr/local/python3.7/bin/pip3.7 /usr/bin/pip3

注意：

linux中自带的是python2，因为便于区分，便更名为python3、pip3

5. 测试

python3pip3 -V
