Python3.7 Scrapy crawl 運行出錯解決方法

安裝的是Python3.7，裝上依賴包和scrapy后運行爬蟲命令出錯

 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

解決方法：

    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])

 

 

將源碼manhole.py中的async參數更改為shark（注意更換全部） 
可以直接點擊錯誤跳轉 
也可以通過文件路徑查找 
D:\Python37\Lib\site-packages\twisted\conch\manhole.py

改完再運行就OK了
