Rails Console Error Output

Question

I just recently updated Ruby(2.3.1) and Rails(5.0.0.1). Now, when I get an error ( any type of error) on the rails console, it's followed by about 15-20 lines starting with 'from/Users....../.rvm/..etc'. Any idea why I am getting so many lines of this error output and if it's normal? How could I fix it? Everything else regarding Ruby/Rails works perfectly fine for me otherwise, so maybe it's just normal output. However, it is a bit of an annoyance.

The commonality in each path seems to be '.rvm'. For example:

  2.3.1 :031 > test
ArgumentError: wrong number of arguments (given 0, expected 2..3)

Rails console uses IRB under the covers, so you're going to have to edit your IRB configuration file, usually located at ~/irbrc, and change the BACK_TRACE_LIMIT value:

IRB.conf[:BACK_TRACE_LIMIT]=0

During a Rails console session, you can also run:

conf.back_trace_limit = 0

There are many more configuration options for IRB (and by extension, Rails console). Check them out at ruby-doc.org.
