安装的是Python3.7,装上依赖包和scrapy后运行爬虫命令出错
1 File "D:\Python37\lib\site-packages\scrapy\extensions\telnet.py", line 12, in <module>
2 from twisted.conch import manhole, telnet
3 File "D:\Python37\lib\site-packages\twisted\conch\manhole.py", line 154
4 def write(self, data, async=False):
5 ^
6 SyntaxError: invalid syntax
7
8 Process finished with exit code 1
解决方法:
1 def write(self, data, shark=False):
2 self.handler.addOutput(data, shark)
3
4 def addOutput(self, data, shark=False):
5 if shark:
6 self.terminal.eraseLine()
7 self.terminal.cursorBackward(len(self.lineBuffer) + len(self.ps[self.pn]))
8
9 self.terminal.write(data)
10
11 if shark:
12 if self._needsNewline():
13 self.terminal.nextLine()
14
15 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 |
