First, you could have ‘overshadowed’ the line function somehow. To determine that, run this from a script or your Command Window:
which line -all
The result should be similar to the displayed result. If it says anything else (particularly ‘line is a variable’ or something similar) that could be the problem. The solution would be to re-name the user function or variable.
If that is not the problem, try running these from a script or your Command Window:
restoredefaultpath
rehash toolboxcache
.
