require 'irbtools'

Hmm. Latest ruby version here. Not sure why I get this error in irb when I type that require.

Perhaps the message could be more indicative of what the problem is? I am not sure what live threads the message is talking about; all I tried was a require 'irbtools'

Thanks for the report. There must be a bug in the loading mechanism of irbtools, which uses threads for faster loading. Does requiring irbtools always lead to this error, or only sometimes? Does `irb -f -r irbtools' work?

[slbug]

same issue here. irb -f -r irbtools does not work too. gem cleanup helps tho.

Hey @shevegen and @slbug

Does this still happen with recent versions of Rails and irbtools?

Closing, please re-open if you still experience this problem…
