[yt-users] Readline service not available

[Elizabeth Tasker]

Hi Chao,

In case Jeff's solution doesn't work, try installing readline using "pip" which is part of the yt package:

~/yt/bin/pip  install readline

For some reason, I get similar problems with readline even though it's blatantly on the system already.
