我就很纳闷了，难道是安装失败了吗，然后又试了一下：scrapy startproject test
显示成功创建，很烦，莫名的错误，度娘一圈没找到什么结果，死马当活马医，打开c:\users\gismi\appdata\local\programs\python\python37\lib\site-packages\twisted\conch\manhole.py看了一眼，发现不对，如下：

为什么这个async的字体有颜色，跟其他变量颜色不一样，难道他是什么关键字？
我又去度娘scrapy async发现果然，async def用来标记一个异步模块。这可一脸懵逼的我在把async改成了async1，颜色变了

试一试，不行再改回来，嘿，这个错误没有了，当然还有其他错，不过也都是应为这个变量名的问题，全部更换成async1后就正常运行了
坑啊，这是什么鬼呦！！！！！
