Need help switching from RVM to RBENV - ruby

Question

Alright so I imploded RVM and switched to rbenv but now I think I'm having all kinds of problems with the gem path. I think some part of my system still thinks gems are supposed to be found with RVM and it's messing everything up. I'm terrible at fixing config issues like this so your help is greatly appreciated.
This is my $PATH:
/Users/home/.rbenv/shims:/Users/home/.rbenv/bin:/Users/home/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/home/.rvm/bin
So as you can see .rvm is still in the $PATH, is this my problem? How do I fix it?
Here is my gem env(This was what I got before I manually moved some directories to better match the path, now I get the same error(below)
as when I run ruby or bundle):
RubyGems Environment:
- RUBYGEMS VERSION: 2.2.2

My current version of ruby is 2.1.2 and it is looking into 2.1.0 still.
Here is my .bash_profile
[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile
export PATH="$HOME/.rbenv/bin:$PATH"
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
Here is my .profile
eval "$(rbenv init -)"
When I run the ruby or bundle command I get this error:
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
from <internal:gem_prelude>:1:in `<compiled>'
I did some tinkering with the path and manually relocated the gem directories, and I think I've done more harm than good. Thanks for the help. If you don't know the answer could someone please comment the best way to completely scrub ruby and the gem path settings so I can get a fresh reinstall? Do I just uninstall rbenv?

Answer 1

My RVM implode script is here -- you can edit is as you like.
https://github.com/sixarm/rvm-implode-systemwide-danger
The script does RVM implode, systemwide, and is dangerous. The script will seek and destroy RVM installations, rvm gems, .rvmrc files, and then search your entire system for lingering files and and references.
Suggestions and pull requests are very welcome. I'm the author.
The entire script is copy/paste below for reference. The link above is probably better because it will have any updates, changes, improvements, etc.
#!/bin/sh
#
# Uninstall RVM (Ruby Version Manager) systemwide:
# THIS IS DANGEROUS.
#
# This script tries to eliminate RVM everywhere on the system,
# by doing these steps:
#
# * Run `rvm implode`
# * Delete all known RVM-related files everywhere on the system.
# * Delete all users' home directory `.rvm` directories and `.rvmrc` files.
# * Uninstall all known RVM gems.
# * Search the system for potential lingering items and print them.
#
# ## Use at your own risk
#
# This script is not advanced:
#
# * it does not do any error checking
# * it does not ensure anything worked
# * it does not guarantee success
#
# If it doesn't work for you, please let us know and we'll improve it.
#
# We welcome feedback, patches, and pull requests.
#
# ## Warnings
#
# Some of the script lines may report missing directories.
#
# For example, a Mac system typically has a /Users/ directory,
# whereas a Linux system typically has a /home/ directory.
# You can delete the lines that you don't need, if you like.
#
# If rvm implode gives errors like this loop:
#
# line 72: /usr/local/rvm/scripts/rvm: No such file or directory
#
# then the rvm setup is bonked and we can delete the rvm script
# by hand then run this script again; rvm implode won't work,
# but the rest of the script will do a decent job of deleting
# any lingering rvm files and reporting any remainders.

Ensure that you are checking all of your "rc" files. This includes ~/.bashrc and ~/bash_login, if they exist.
Using a tool like grep can help you find them.
grep 'rvm' -l ./.* maybe, to get the filenames that any reference to rvm may be in.
