The curious case of frozen/hanging terminal when you run a`rails g migration` command
Raw
rails_g_migration.md

Ref: https://stackoverflow.com/questions/24622568/rails-generate-model-hangs

So, I ran into a mysterious situation where running a rails g migration ... command on my terminal freezes/hangs for a really long time.

Running ps aux | grep spring gave me a clue into what was going on.

I got the following:

esther            4201   0.0  0.0  2480224   2692   ??  S     6Sep17   0:00.82 spring server | panacea | started 191 hours ago
esther           41548   0.0  0.0  2432804    840 s002  S+   12:00PM   0:00.00 grep spring

It turned out I had a rails console server that had been running for 191hrs... Stopping that server resolved the issue.

Have found this gist a couple of times when this happened, but I couldn't find a running rails console. The way to kill the server was by running spring stop
