CentOS 6.5 下安装python 2.7.8+Scrapy环境
一、安装Python2.7.8
- 更新CentOS lib库文件
yum -y update
- 安装开发工具包
yum groupinstall -y development
- 安装扩展包
yum install -y zlib-dev openssl-devel sqlite-devel bzip2-devel
- 下载Python2.7.8
wget http://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz
- 解压Python2.7.8
tar -xvf Python-2.7.8.tar.xz
- 进入Python2.7.8目录
cd Python-2.7.8
- 编译安装Python2.7.8
./configure
make && make altinstall
二、解决Yum不支持Python2.7的问题
- 将老的Python程序进行备份
mv /usr/bin/python /usr/bin/python2.6.6
- 建立新的Python链接
ln -s /usr/local/bin/python2.7 /usr/bin/python
- 修改/usr/bin/yum文件
vi /usr/bin/yum
将第一行的 #!/usr/bin/python 改为 #!/usr/bin/python2.6.6
三、安装setuptools 和 pip
- 下载setuptools
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz
- 解压setuptools
tar -xvf setuptools-1.4.2.tar.gz
- 进入setuptools目录
cd setuptools-1.4.2
- 通过已安装的Python2.7.8安装setuptools
python setup.py install
- 安装 pip
easy_install pip
-
curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python2.7 -
四、安装libxslt-devel支持lxml
