无法在Python2.7中导入socketio (python-socketio)

Question

在python 2中尝试导入socketio时出现此错误：

root@udacity:~/Desktop/CarND-Capstone-master/ros# python
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import socketio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/socketio/__init__.py", line 3, in <module>
    from .client import Client
  File "/usr/local/lib/python2.7/dist-packages/socketio/client.py", line 6, in <module>
    import engineio
  File "/usr/local/lib/python2.7/dist-packages/engineio/__init__.py", line 3, in <module>
    from .client import Client
  File "/usr/local/lib/python2.7/dist-packages/engineio/client.py", line 302
    'Unexpected response from server') from None
                                          ^
SyntaxError: invalid syntax

尝试重新安装/安装socketio和engineio，但似乎无法使其正常工作。我应该提一下，我是在Ubuntu虚拟机上运行的。

Answer 1

我找到了答案，如上所述，这是一个引擎故障。在我的需求文件中的socketio之前安装它起作用了。特别是，我使用python-socketio==4.4.0和python-engineio==3.11.2

python-engineio==3.11.2
python-socketio==4.4.0
