Rbenv does not rephrase correctly and makes pads

Question

The bottom line is that rbenv does not do gaskets. I have run out of ideas on what might be the problem. After a few days hitting my head against the wall to fix it, but it didn’t help, I think the time has come to ask for help.

I'm trying to make the switch from RVM to rbenv, so this obviously could be a factor here. Any ideas / help would be great.

Here's what happens:

[09:38] ~ $ gem install pry Fetching: pry-0.10.2.gem (100%) Successfully installed pry-0.10.2 1 gem installed [09:39] ~ $ rbenv rehash [09:40] ~ $ pry bash: pry: command not found [09:40] ~ $ rbenv which pry rbenv: pry: command not found [09:40] ~ $ which pry which: no pry in (/home/caveman/.rbenv/plugins/ruby-build/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/home/caveman/.rbenv/plugins/ruby-build/bin:/home/caveman/.rbenv/shims:/home/caveman/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl) [09:41] ~ $ ~/.gem/ruby/2.2.0/bin/pry [1] pry(main)> puts "I'm working now" I'm working now [09:43] ~ $ gem list | grep pry pry (0.10.2) 

Here is my gem environment:

 [09:44] ~ $ gem env RubyGems Environment: - RUBYGEMS VERSION: 2.4.8 - RUBY VERSION: 2.2.0 (2014-12-25 patchlevel 0) [x86_64-linux] - INSTALLATION DIRECTORY: /home/caveman/.gem/ruby/2.2.0 - RUBY EXECUTABLE: /home/caveman/.rbenv/versions/2.2.0/bin/ruby - EXECUTABLE DIRECTORY: /home/caveman/.gem/ruby/2.2.0/bin - SPEC CACHE DIRECTORY: /home/caveman/.gem/specs - SYSTEM CONFIGURATION DIRECTORY: /home/caveman/.rbenv/versions/2.2.0/etc - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /home/caveman/.gem/ruby/2.2.0 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :backtrace => false - :bulk_threshold => 1000 - "gem" => "--no-document" - REMOTE SOURCES: - https://rubygems.org/ - SHELL PATH: - /home/caveman/.rbenv/versions/2.2.0/bin - /usr/lib/rbenv/libexec - /home/caveman/.rbenv/plugins/ruby-build/bin - /home/caveman/.rbenv/shims - /home/caveman/.rbenv/bin - /home/caveman/.rbenv/shims - /home/caveman/.rbenv/bin - /home/caveman/.rbenv/plugins/ruby-build/bin - /home/caveman/.rbenv/shims - /home/caveman/.rbenv/bin - /usr/local/sbin - /usr/local/bin - /usr/bin - /usr/lib/jvm/default/bin - /usr/bin/site_perl - /usr/bin/vendor_perl - /usr/bin/core_perl 

Here is my .bashrc file:

 [09:46] ~ $ cat .bashrc # If not running interactively, don't do anything [[ $- != *i* ]] && return # If I don't set this, gem reverts back to nonexistent RVM directory. export GEM_HOME=$(ruby -e 'print Gem.user_dir') export GEM_PATH=$(ruby -e 'print Gem.user_dir') export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)" export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH" 

And here is the .bash_profile:

 [09:52] ~ $ cat .bash_profile [[ -f ~/.bashrc ]] && . ~/.bashrc source ~/.profile export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)"

I suspect a problem with your .bashrc. It should not contain:

 # If I don't set this, gem reverts back to nonexistent RVM directory. export GEM_HOME=$(ruby -e 'print Gem.user_dir') export GEM_PATH=$(ruby -e 'print Gem.user_dir') export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)" export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH" 

Of my ~ / .bashrc, ~ / .profile and ~ / .bash_profile files, only the latter has a configuration for rbenv:

 # echo Using rbenv... export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)" 

This was created when I installed rbenv, which matches the settings for my other systems on which I use rbenv, including those that were previously installed by RVM.

Your dual PATH assignments look like a criminal. Compare PATH for my system with yours specified in gem env :

  - /Users/ttm/.rbenv/versions/2.2.3/bin - /Users/ttm/.rbenv/libexec - /Users/ttm/.rbenv/plugins/ruby-build/bin - /Users/ttm/.rbenv/plugins/rbenv-whatis/bin - /Users/ttm/.rbenv/plugins/rbenv-vars/bin - /Users/ttm/.rbenv/plugins/rbenv-use/bin - /Users/ttm/.rbenv/plugins/rbenv-update/bin - /Users/ttm/.rbenv/plugins/rbenv-update-rubies/bin - /Users/ttm/.rbenv/plugins/rbenv-gemset/bin - /Users/ttm/.rbenv/plugins/rbenv-env/bin - /Users/ttm/.rbenv/plugins/rbenv-each/bin - /Users/ttm/.rbenv/shims - /Users/ttm/.rbenv/bin 

Similarly, my which pry returns:

 /Users/ttm/.rbenv/shims/pry 

Using the rbenv env plugin shows:

 RBENV_VERSION=2.2.3 RBENV_GEMSET_ALREADY=yes RBENV_ROOT=/Users/ttm/.rbenv RBENV_HOOK_PATH=:/Users/ttm/.rbenv/rbenv.d:/usr/local/etc/rbenv.d:/etc/rbenv.d:/usr/lib/rbenv/hooks:/Users/ttm/.rbenv/plugins/rbenv-default-gems/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-gemset/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-readline/etc/rbenv.d:/Users/ttm/.rbenv/plugins/rbenv-vars/etc/rbenv.d PATH=/Users/ttm/.rbenv/versions/2.2.3/bin:/Users/ttm/.rbenv/libexec:/Users/ttm/.rbenv/plugins/ruby-build/bin:/Users/ttm/.rbenv/plugins/rbenv-whatis/bin:/Users/ttm/.rbenv/plugins/rbenv-vars/bin:/Users/ttm/.rbenv/plugins/rbenv-use/bin:/Users/ttm/.rbenv/plugins/rbenv-update/bin:/Users/ttm/.rbenv/plugins/rbenv-update-rubies/bin:/Users/ttm/.rbenv/plugins/rbenv-gemset/bin:/Users/ttm/.rbenv/plugins/rbenv-env/bin:/Users/ttm/.rbenv/plugins/rbenv-each/bin:/Users/ttm/.rbenv/shims:/Users/ttm/.rbenv/bin:/Users/ttm/.pyenv/shims:/Users/ttm/.pyenv/bin:/Users/ttm/perl5/perlbrew/bin:/Users/ttm/perl5/perlbrew/perls/perl-5.18.1/bin:/Users/ttm/bin:/usr/local/mysql-5.6.16-osx10.7-x86_64/bin:/Users/ttm/libsmi/bin:/usr/local/git/bin:/usr/local/bin:/Library/PostgreSQL/9.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin RBENV_SHELL=bash RBENV_DIR=/Users/ttm RUBYLIB=/Users/ttm/.rbenv/rbenv.d/exec/gem-rehash: 

I would take the following steps:

• Modify ~ / .bashrc and others by removing any lines related to rbenv and / or RVM. RVM uses all three init files, plus .zshrc, while rbenv only seems to concern ~ / .bash_profile.
• Close the terminal session. Restore it.
• Confirm that PATH is free of all references to RVM and rbenv.
• Reinstall rbenv according to the Installation instructions. It will not undo the current installation, but instead will reinstall the changes to the ~ / .bash_profile file.
• Close the terminal session again and open it again.

rbenv must be properly initialized.
