  • Scrapy安装

    一、安装python

    官网下载python后安装,并将python路径(C:Python27;C:Python27Scripts;)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 (md5pgp)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:Python27Scripts>easy_install.exe service_identity-14.0.0-py2.py3-none-any.egg

    进行安装。
