async

是用于协同程序的python关键字，因此不能像变量一样正常使用它。尝试将该行（程序中的第224行）更改为

def expect（self、pattern、timeout=-1、searchwindowsize=-1、async\uxAE=False）：

在安装Python 3.8之后，我遇到了相同的错误

ipython

按照中的建议升级

pexpect

，为我解决了问题：

$ ipython
[ . . . ]
def expect(self, pattern, timeout=-1, searchwindowsize=-1, async=False):
                                                               ^
SyntaxError: invalid syntax

在这里添加你的代码谢谢你的回答，但我只是键入ipython命令，整个事情都是由zorin terminal给我的。我想也许我应该重新安装zorin操作系统我可能在安装ipythonI时做错了smth我不认为您使用的平台有任何问题，尽管重新安装可能会有所帮助

sudo apt-get remove python-pexpect python3-pexpect

sudo pip3 install --upgrade pexpect
