python3之安装、pip、setuptools

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
mkdir -p /usr/local/python356
tar zxvf Python-3.6.5.tgz
cd Python-3.6.5
./configure --prefix=/usr/local/python356
make
make install
ln -s /usr/local/python356/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python356/bin/pip3 /usr/local/bin/pip3
pip3 install --upgrade pip  #更新pip
pip3 install ipython  #安装ipython

unzip setuptools-39.2.0.zip
cd setuptools-39.2.0
python33 setup.py build #测试环境
python33 setup.py install #安装

RuntimeError: Compression requires the (missing) zlib module

yum install zlib zlib-devel -y
#然后：进入到安装python的源码包目录下（这步很重要）我的是python33.6版本
cd /home/tools/python33.6
make #重新编译
make install #重新安装一下
#然后：进入要安装的setuptool源码目录下：
python33 setup.py install 
#使用新安装的python33.6安装，不要使用系统自带的python安装。
