TabError: inconsistent use of tabs and spaces in indentation

[qingchunlizhi]

When I run "rosrun teleop_twist_keyboard teleop_twist_keyboard.py",I get this error:
File "/opt/ros/melodic/lib/teleop_twist_keyboard/teleop_twist_keyboard.py", line 83
pub = rospy.Publisher('cmd_vel', Twist, queue_size = 1)
^
TabError: inconsistent use of tabs and spaces in indentation

then I replace all the "Tab" to "space" ,it works!!
So, does this code need to be modified?

That's odd. There were definitely mixed tabs and spaces in that file, but they'd been there for quite a few years, so I'm surprised that this is the first time it's been a problem.

Anyway, this will be fixed in the next release.

The fix for this has been released in version 0.6.2 . Please keep an eye on the release tag on ROS Discourse to see when this reaches the public repositories for your version of ROS.
