python中安装Scrapy模块依赖包汇总

本地虚拟环境开发完成之后，上线过程中需要一一安装依赖包，做个记录如下：

CentOS 安装python3.5.3

wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgztar -xf Python-3.5.3.tgz cd Python-3.5.3./configure --prefix=/usr/local/python353 make & make install

完成安装python3.5.3，在不删除系统自带的python2.x情况下，做几个软链：

#做python3软链ln -s /usr/local/python353/bin/python3 /usr/local/bin/#pip3软链ln -s /usr/local/python353/bin/pip3 /usr/local/bin/

上传程序，安装scrapy及其依赖包：

#user agent包pip3 install fake-useragent -i https://pypi.douban.com/simple/#pymysql包pip3 install pymysql -i https://pypi.douban.com/simple/#PooledDB依赖包pip3 install DBUtils -i https://pypi.douban.com/simple/#PIL模块依赖包pip3 install Image -i https://pypi.douban.com/simple/

在Centos系统中安装过程中，出现一个较为淡疼的问题：系统没有安装sqlite3，故此一直提示：
解决上面问题，下载sqlite3

sudo wget http://www.sqlite.org/2017/sqlite-autoconf-3190300.tar.gz

编译安装：

tar zxvf sqlite-autoconf-3190300.tar.gz cd sqlite-autoconf-3190300./configure --prefix=/usr/local/sqlite3make && make install

重新编译Python，找到Python3.5.3的安装文件路径，编辑setup.py脚本，找到 “sqlite3”

sqlite_inc_paths = [ '/usr/include','/usr/include/sqlite','/usr/include/sqlite3','/usr/local/include','/usr/local/include/sqlite','/usr/local/include/sqlite3',]

在最后一行加入sqlite3编译安装路径，如下：

sqlite_inc_paths = [ '/usr/include','/usr/include/sqlite','/usr/include/sqlite3','/usr/local/include','/usr/local/include/sqlite','/usr/local/include/sqlite3','/usr/local/sqlite3',]

重新编译Python3.5.3:

./configure --prefix=/usr/local/python353make && make install
