Linux 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源码

1) 下载
# wget http://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz
2)解压
# tar -xvf Python-3.7.1.tar.xz && cd Python-3.7.1/

3.执行配置文件,编译,编译安装

# ./configure --prefix=/usr/local/python37
# make && make install

安装完成没有提示错误便安装成功了

4.建立软连接

# mv /usr/bin/python /usr/bin/python_bak
# ln -s /usr/local/python37/bin/python3.7 /usr/bin/python

# ln -s /usr/local/python37/bin/pip3.7 /usr/bin/pip

5.测试Python是否可用

# python
Python 3.7.1 (default, Jan 14 2019, 10:30:01) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print("hello world!")
hello world!
>>> exit()

# pip  --version
pip 10.0.1 from /usr/local/python37/lib/python3.7/site-packages/pip (python 3.7)

注:

安装完之后可能导致yum不能用,报错为:

# yum -y install redis 
  File "/usr/bin/yum", line 30
    except KeyboardInterrupt, e:
                            ^
SyntaxError: invalid syntax

解决办法:

# vi /usr/bin/yum  和 /usr/libexec/urlgrabber-ext-down

将第一行"#!/usr/bin/python" 改为 "#!/usr/bin/python2.7"即可。
