在ubuntu里，zlib叫zlib1g，相应的zlib-devel叫zlib1g.dev。默认的安装源里没有zlib1g.dev。要在packages.ubuntu.com上找。

$sudo apt-get install ruby

然后再装zlib1g-dev就可以了

$sudo apt-get install zlib1g-dev

1. 安装必备的软件包

centos: yum -y groupinstall development zlib zlib-devel

ubuntu: sudo apt-get install zlib1g-dev

2. 下载python3.6

3. 检查是否成功

which python3

python3 -V

4. 创建软链接

cd /usr/bin

mv python python.backup

ln -s /usr/local/bin/python3 /usr/bin/python

检测

>>> python3.6

安装pip3

1.官网下载zip包。

https://pypi.python.org/pypi/setuptools

tar -zxvf setuptools-19.6.tar.gz //解压

cd setuptools-19.6

python3 setup.py build//编译

python3 setup.py install //安装

install 的时候会报错，我们需要在linux中安装zlib-devel包，进行支持。

yum install zlib-devel

需要对python3.5进行重新编译安装

cd Python3.5

make && make install

再重新安装setuptools

python3 setup.py build

python3 setup.py install

安装pip

wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

tar -zxvf pip-8.0.2.tar.gz

cd pip-8.0.2

python3 setup.py build

python3 setup.py install

ImportError: cannot import name 'HTTPSHandler'

yum install openssl-devel

==继续重新安装编译python3.5(其他的不需要重新编译)==

error
