下载安装scrapy

告诉我我不是一个人被安装scrapy坑死

安装scrapy

python3.7 ,win10

1、下载wheel,twisted这两个我是直接用pycharm的setting下载的

下载pywin32

1、我使用pycharm安装pywin32不起作用只能去官网下载与python3.7对应的版本，下载的pywin32放在python的site-packages文件下

2、pywin32下载: https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/

3、安装pywin32一直next,但是我弄的时候报了如下错并解决如下：

    -Python version 3.7 required, which was not found in the registry

解决上面的错误，新建一个文件register.py,并把他和pywin32在同一个目录下，贴下如下代码：

from __future__ import print_function
 
 
import sys
 
try:
    from winreg import *
except ImportError:
    from _winreg import *
 
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
 
regpath = "SOFTWARE\Python\Pythoncore\{0}\".format(version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "{0};{1}\Lib\;{2}\DLLs\".format(
    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()

保存之后进入cmd，切换到存储该py文件的目录，执行python registed.py即可重新运行exe文件进行pywin32的安装。

用pytcharm下载scrapy

1、下载的文件是Scrapy我把他手动改成scrapy，scrapy-1.7.3.dist-info

2、配置环境变量把scrapy的路径
