Ubuntu16.04安装爬虫框架scrapy

321231255

scrapy框架需要在Python 2.7，lxml,OpenSSL,pip程序或库的基础之上创建。
因此 ，首先，先检查下是否包含上述四个程序或库

1 2 3 4 5

kuku@worker1:~$ python Python 2.7.12 (default, Jul  1 2016, 15:12:24) [GCC 5.4.0 20160609] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>

可以看到Ubuntu16.04已经预置了python 2.7
接着查看是否还有lxml

1 2 3 4 5 6 7

>>> import lxml Traceback (most recent call last):   File "<stdin>", line 1, in <module> ImportError: No module named lxml >>> >>> import OpenSSL >>>

发现没有lxml，有OpenSSL,于是先安装lxml

1	kuku@worker1:~$ sudo apt-get install python-lxml

重新进入

1 2 3 4 5 6

kuku@worker1:~$ python Python 2.7.12 (default, Jul  1 2016, 15:12:24) [GCC 5.4.0 20160609] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import lxml >>>

没有报错。为保证后续正确安装，需依次执行

1	kuku@worker1:~$ sudo apt-get install python-dev

1	kuku@worker1:~$ sudo apt-get install libevent-dev

1	kuku@worker1:~$ sudo apt-get install python-pip

1	kuku@worker1:~$ sudo pip install --upgrade pip

最后执行

1	kuku@worker1:~$ pip install Scrapy

即可完成Scrapy的安装，查看下scrapy相关命令

1	kuku@worker1:~$ scrapy

然后可以创建一个新的项目

1 2 3 4 5 6 7 8 9

kuku@worker1:~$ scrapy startproject newproject New Scrapy project 'newproject', using template directory '/usr/local/lib/python2.7/dist-packages/scrapy/templates/project', created in:     /home/kuku/newproject You can start your first spider with:     cd newproject     scrapy genspider example example.com kuku@worker1:~$ kuku@worker1:~$ sudo apt install tree

使用tree看下newproject文件目录

1	kuku@worker1:~$ tree newproject/

接下来可以根据自己需要对里面文件进行相应的编辑，以满足自己需求。
