标签：/usr   变量   python版本   ++   centos6.9   pca   pip3   evel   依赖   

yum -y install wget zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel gcc gcc++

2、下载python包、解压、编译安装

wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
tar -xzvf ./Python-3.6.0.tgz -C /usr/local/src/
cd /usr/local/src/Python-3.6.0/
./configure --prefix=/usr/local/python
make
make install

3、更改环境变量并使其生效、验证

vim ~/.bash_profile
PATH=$PATH:$HOME/bin
# 改为：
PATH=$PATH:$HOME/bin:/usr/local/python/bin

source ~/.bash_profile

python3 -V

4、设置默认python版本

mv /usr/bin/python /usr/bin/python2.6
ln -s /usr/local/python/bin/python3.6 /usr/bin/python

5.核对Python版本

python -V
Python 3.6.0

python2.6 -V
Python 2.6.6

6、更改yum程序，yum程序要用到python 2.X

vi /usr/bin/yum
将
#!/usr/bin/python
改成
#!/usr/bin/python2.6

7、pip安装模块

pip3 install requests
