Scrapy安装
一、安装python
官网下载python后安装,并将python路径(C:\Python27;C:\Python27\Scripts;)加入环境变量,验证是否安装ok:
>python Python 2.7.9 (default, Dec 10 2014, 12:28:03) [MSC v.1500 64 bit (AMD64)] on win 32 Type "help", "copyright", "credits" or "license" for more information. >>>
二、安装setuptools
官网下载setuptools(http://pypi.python.org/pypi/setuptools)安装
windows下可下载ez_setup.py文件,然后执行:
python ez_setup.py
进行安装。
三、安装Scrapy
第二步完成后,pip就已经被装好了,可以直接用下面的命令安装Scrapy。
pip install scrapy
四、Tips
1、ImportError: Error loading object'scrapy.core.downloader.handlers.s3.S3DownloadHandler'
如果运行scrapy后出现下面的错误:
ImportError: Error loading object'scrapy.core.downloader.handlers.s3.S3DownloadHandler': DLL load failed: Could not find the specified module.
可安装:pywin32-218.win32-py2.7.exe(选择你对应的机器版本)
2、You do not have the service_identity module installed
如果运行scrapy后出现下面的警告:
UserWarning: You do not have the service_identity module installed. Please install it from <https://pypi.python.org/pypi/service_identity>. Without the service_identity module and a recent enough pyOpenSSL tosupport it, Twisted can perform only rudimentary TLS client hostnameverification. Many valid certificate/hostname mappings may be rejected.
可以来这里下载安装:https://pypi.python.org/pypi/service_identity#downloads
windows平台下下载service_identity-14.0.0-py2.py3-none-any.whl (md5, pgp)后,需要把后缀名改为.egg,然后复制到python安装目录下的Scripts文件夹下,在命令行中执行:
C:\Python27\Scripts>easy_install.exe service_identity-14.0.0-py2.py3-none-any.egg
进行安装。
