rails: command not found

[Bill Barnett]

OK, seems I do this dance everytime I start a green field Rails project. Posting here so I'll have somewhere to consult the rest of my career...

Here's the deal (not rbenv)

chip: agilous/monmentum $ rails s

rbenv: rails: command not found

The `rails' command exists in these Ruby versions:

  1.8.7-p334

  1.9.3-p374

  1.9.3-p392

  1.9.3-p448

  2.0.0-p247

  2.0.0-p353

chip: agilous/monmentum $ which rails

./bin/rails

chip: agilous/monmentum $ echo $PATH

./bin:/usr/local/bin:/Users/bbarnett/bin:/Users/bbarnett/.rbenv/shims:/Users/bbarnett/.rbenv/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/go/bin:/usr/local/share/npm/bin

What am I continuing to miss?!

Thanks

`source ~/.bash_profile` and try again.

That's the secret sauce! Thank you!

[Chris Moore]

I wish someone smarter than me would explain why that happens.

rbenv rehash?  Any time you install a global gem that has an executable, you need to have it re-search your path and whatnot.  I may not be explaining that 100% right without diving into the rbenv internals.  Use meteor and npm, less issues ;)

Nope, it's not rbenv. It's the local bin folder. Doug says `hash -r` would update the lookup cache and achieve the same result.

It is rbenv, see below in the first error.  rbenv rehash does the same thing as hash -r, I believe.

What's interesting is that rbenv is recreating the shims based on what binstubs it thinks it needs for _any_ of it's versions. The trick is to not remove the shim, but the version's tracking of the bin:

$ find ~/.rbenv/versions/*/bin -name 'rails' | xargs rm

Then you can use 'rbenv rehash'. I have the same problem the heroku script as well. If you don't delete the file from the versions/*/bin directory then `rbenv rehash` will just recreate the shim.
