win10 安装scrapy

时间：2023-09-05 20:49:44

在win10的环境下安装scrapy，并不能直接按照官网的手册（http://doc.scrapy.org/en/1.0/intro/install.html）一次性安装成功，根据我自己的安装过程中遇到的问题，特意整理了一下安装过程

1.下载安装python2.7.11

https://www.python.org/

 

2.安装完成之后，把安装路径和脚本路径添加到path中，譬如：C:\Python27\;C:\Python27\Scripts\;

 

3.安装pywin32，在下面的连接中下载最新版的pywin32

http://sourceforge.net/projects/pywin32/files/pywin32/

我在安装pywin32过程中遇到错误提示：

python version 2.7 required,which was not found in the registry

这是因为注册表不能识别出python2.7，解决方法就是新建一个register.py文件，运行下面的代码

#

# script to register Python 2.0 or later for use with win32all

# and other extensions that require Python registry settings

import sys

from _winreg import *

# tweak as necessary

version = sys.version[:3]

installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)

installkey = "InstallPath"

pythonkey = "PythonPath"

pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (

    installpath, installpath, installpath

)

def RegisterPy():

    try:

        reg = OpenKey(HKEY_CURRENT_USER, regpath)

    except EnvironmentError as e:

        try:

            reg = CreateKey(HKEY_CURRENT_USER, regpath)

            SetValue(reg, installkey, REG_SZ, installpath)

            SetValue(reg, pythonkey, REG_SZ, pythonpath)

            CloseKey(reg)

        except:

            print "*** Unable to register!"

            return

        print "--- Python", version, "is now registered!"

        return

    if (QueryValue(reg, installkey) == installpath and

        QueryValue(reg, pythonkey) == pythonpath):

        CloseKey(reg)

        print "=== Python", version, "is already registered!"

        return

    CloseKey(reg)

    print "*** Unable to register!"

    print "*** You probably have another Python installation!"

if __name__ == "__main__":

    RegisterPy()

运行成功后显示：python 2.7 is already registered，然后再次安装pywin32

 

4.接着安装lxml，并不能直接使用命令pip install lxml来安装，此时就使用第三方的安装方法，到这里（http://www.lfd.uci.edu/~gohlke/pythonlibs/）下载文件：

lxml-3.5.0-cp27-none-win32.whl

然后在存放该下载文件的目录下执行命令：pip install lxml-3.5.0-cp27-none-win32.whl

 

5.运行命令：pip install scrapy来安装scrapy，如果遇到如下错误提示：

Microsoft Visual C++ 9.0 is required Unable to find vcvarsall.bat

则到这里：https://www.microsoft.com/en-us/download/details.aspx?id=44266 下载并安装vc++插件
