scrapy安装

刚买的阿里云服务器，准备安装scrapy

root登陆

首先安装下面这些~

apt-get install build-essential

apt-get install python-dev

apt-get install libxml2-dev

apt-get install libxslt1-dev

apt-get install python-setuptools

然后执行easy_install Scrapy

但是报错了：

in/ld: cannot find -lz所以安装apt-get install zlib1g-dev，之后easy_install Scrapy

再报错，需要pip install pyasn1，然后easy_install Scrapy

继续报错 c/_cffi_backend.c:15:17: fatal error: ffi.h: No such file or directory

需要 apt-get install libffi-dev，再次easy_install Scrapy

再报错 openssl.c:423:27: fatal error: openssl/e_os2.h: No such file or directory

于是apt-ge install openssl后easy_install Scrapy

但是不顶用，于是接下来安装这个：

apt-get install libssl-dev，安装完后easy_install Scrapy

Finished processing dependencies for Scrapy

安装成功~
