96、python version 3.6 required,which was not fount in the registry（python3.6安装scrapy），fountscrapy,在安装scrapy时

在安装scrapy时遇到问题

环境：win10(64位）， Python3.6（64位）

安装scrapy：

1、安装wheel（安装后，便支持通过wheel文件安装软件）

pip3 install wheel

2、安装lxml、pyopenssl

lxml：解析XML的库，很强大，做爬虫BS4,selenium,XPATH都会用到

pip3 install lxmlpip3 install pyopenssl

3、安装pywin32

下载网址：https://sourceforge.net/projects/pywin32/files/pywin32/

根据自己python版本下载64位或32位（(注意：pywin32版本跟随Python版本，即如果win是64位，但python是32位，pywin32要装32位的，与win无关））

双击安装（可能会遇到下列错误是注册表问题）

安装第三方库出现Python version 3.6 required, which was not found in the registry错误解决

建立一个文件 register.py 内容如下. 然后执行该脚本.

import sysfrom winreg import *# tweak as necessaryversion = sys.version[:3]installpath = sys.prefixregpath = "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()

4、下载twisted

下载twisted的wheel文件：http://www.lfd.uci.edu/~gohlke/pythonlibs/

pip3 install 下载目录\Twisted-17.9.0-cp36-cp36m-win_amd64.whl

安装可能会报错

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

说明电脑需要安装visual C++ Build Tools 2015

5、安装scrapy

pip3 install scrapy

6、大功告成

这是今天安装scrapy时遇到的问题 明天会发一篇关于scrapy的详细随笔有兴趣的可以关注
