Centos正确安装scrapy

1.安装环境

系统：Centos 6.8 python版本：2.7

2.安装步骤

1）python2.6升级到2.7

[[email protected] ~]#rpm -ivh http://mirrors.aliyun.com/epel/6/x86_64/epel-release-6-8.noarch.rpm
[[email protected] ~]#rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/ius/archive/CentOS/6/x86_64/ius-release-1.0-13.ius.centos6.noarch.rpm
[[email protected] ~]#yum install  python27 python27-devel python27-pip -y
[[email protected] ~]#mv /usr/bin/python /usr/bin/python2.6.6
[[email protected] ~]#ln -s /usr/bin/python2.7 /usr/bin/python
[[email protected] ~]#mv /usr/bin/pip /usr/bin/pip2.6
[[email protected] ~]#ln -s /usr/bin/pip2.7 /usr/bin/pip

2）解决升级python版本后yum不可用的问题

[[email protected] ~]#vi /usr/bin/yum

将#!/usr/bin/python修改为 #!/usr/bin/python2.6.6

3）安装scrapy 

[[email protected] ~]#pip install  scrapy

可以看到，安装过程报错。

解决办法如下：

 [[email protected] ~]#yum install python-devel gcc gcc-c++ openssl-devel -y     

 [[email protected] ~]#pip install  scrapy

ok，成功啦~~~
