环境: linux(CentOS 7)
python3.6安装源：
下载地址：https://www.python.org/ftp/python
安装路径：
/usr/local/python3.6
首先，创建安装目录：
mkdir /usr/local/python3.6
然后，下载安装并解压：
wget --no-check-certificate 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
编译安装：
./configure --prefix=/usr/local/python3.6
make
make install
安装完成后，创建python3链接：
ln -s /usr/local/python3.5/bin/python3 /usr/bin/python3
这里抛出了一个error：
zipimport.ZipImportError: can't decompress data; zlib not available
需要下载zlib后，重新编译:
yum install zlib.i686
yum install zlib-devel.x86_64
make install
setuptools安装源：
https://pypi.org/project/setuptools/
接着安装setuptools：
wget https://files.pythonhosted.org/packages/1a/04/d6f1159feaccdfc508517dba1929eb93a2854de729fa68da9d5c6b48fa00/setuptools-39.2.0.zip
unzip setuptools-39.2.0.zip
cd setuptools-39.2.0/
python3 setup.py install
接着进入安装目录重新编译：
cd /usr/local/Python-3.6.5
make && make install
pip安装源：
https://pypi.org/project/pip/
接下来安装pip：
wget --no-check-certificate https://files.pythonhosted.org/packages/ae/e8/2340d46ecadb1692a1e455f13f75e596d4eab3d11a57446f08259dee8f02/pip-10.0.1.tar.gz
tar -zxvf pip-10.0.1.tar.gz
cd pip-10.0.1/
python3 setup.py install
接着进入安装目录重新编译：
cd /usr/local/Python-3.6.5
make && make install
创建pip3链接：
ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip3
下面使用pip3验证一下：
pip3 install requests
抛出异常：
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
安装openssl以及openssl-devel
yum install openssl
yum install openssl-devel
重新编译：
make && make install
将python路径添加至环境变量：
vi /etc/profile
添加：
export PATH=/usr/local/python3.6/bin:$PATH
source /etc/profile # 立即生效
