pyspider

环境：centos6.4

1.安装Python

wget https://www.python.org/ftp/python/3.5.4/Python-3.5.4.tar.xz
xz -d ***.tar.xz
tar -xvf  ***.tar
cd Python3 
yum install -y gcc 
./configure --prefix=/usr/local/python3 
make && make install 

[pip error while installing Python: “Ignoring ensurepip failure: pip 8.1.1 requires SSL/TLS”](https://stackoverflow.com/questions/37723236/pip-error-while-installing-python-ignoring-ensurepip-failure-pip-8-1-1-requir)
解决：
CentOS
yum install openssl-devel
In addition it is recommended to install the following.
yum install zlib-devel bzip2-devel sqlite sqlite-devel openssl-devel

(Unix设计思想是一个工具只做一件事，tar是文件打包，gzip是压缩。）
（.tgz是.tar.gz格式的简写）

使用--prefix的原因：配置安装的路径

建立软连接，在命令行输入python3，即可调出Python3，即多版本共存

ln -sf /usr/local/python3/bin/python3.5 /usr/local/bin/python3

pip

wget --no-check-certificate https://github.com/pypa/pip/archive/9.0.1.tar.gz
tar -zvxf 9.0.1
cd pip-9.0.1
# 使用 Python 3 安装
python3 setup.py install
创建链接：
sudo ln -s /usr/local/python3/bin/pip /usr/bin/pip3

virtualenv

pip3 install virtualenv
python3 -m virtualenv env
source env/bin/activate

pyspider
pip install pyspider
