Linux環境下配置python3環境

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

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

tar -xzvf  Python-3.6.5.tgz

cd Python-3.6.5

./configure --prefix=/usr/local/python3

make && make install

# 需要提前將/usr/bin/下的原python2環境的python、 pip名字改掉，以免發生衝突 
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python

ln -s /usr/local/python3/bin/pip3.6 /usr/bin/pip
