1. 问题
使用 rospy 时遇到报错 SyntaxError: invalid syntax
Traceback (most recent call last):File "rtsp_to_rostopic.py", line 4, in <module>import rospyFile "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/__init__.py", line 49, in <module>from .client import spin, myargv, init_node, \File "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/client.py", line 60, in <module>import rospy.impl.initFile "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/impl/init.py", line 54, in <module>from .tcpros import init_tcprosFile "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/impl/tcpros.py", line 45, in <module>import rospy.impl.tcpros_serviceFile "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/impl/tcpros_service.py", line 54, in <module>from rospy.impl.tcpros_base import TCPROSTransport, TCPROSTransportProtocol, \File "/usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/impl/tcpros_base.py", line 160(e_errno, msg, *_) = e.args^
SyntaxError: invalid syntax
2. 解决问题
参考连接：https://answers.ros.org/question/368457/do-i-have-an-error-with-rospy-file-tcpros_basepy/
修改报错文件 /usr/local/miniconda3/envs/py2/lib/python2.7/site-packages/rospy/impl/tcpros_base.py 其中 160 行即可
# (e_errno, msg, *_) = e.args 原文件内容
(e_errno, msg) = e.args
3. 备注：pip 安装 rospy
pip install --extra-index-url https://rospypi.github.io/simple/ rospy
