Python3.7 Scrapy crawl 运行出错解决方法

安装的是Python3.7,装上依赖包和scrapy后运行爬虫命令出错

  File "D:\Python37\lib\site-packages\scrapy\extensions\telnet.py", line 12, in <module>
from twisted.conch import manhole, telnet
File "D:\Python37\lib\site-packages\twisted\conch\manhole.py", line 154
def write(self, data, async=False):
^
SyntaxError: invalid syntax Process finished with exit code 1

解决方法:

     def write(self, data, shark=False):
self.handler.addOutput(data, shark) def addOutput(self, data, shark=False):
if shark:
self.terminal.eraseLine()
self.terminal.cursorBackward(len(self.lineBuffer) + len(self.ps[self.pn])) self.terminal.write(data) if shark:
if self._needsNewline():
self.terminal.nextLine() self.terminal.write(self.ps[self.pn])

将源码manhole.py中的async参数更改为shark(注意更换全部) 
可以直接点击错误跳转 
也可以通过文件路径查找 
D:\Python37\Lib\site-packages\twisted\conch\manhole.py

改完再运行就OK了
