I have this line eval "$(rbenv init - zsh)" in my .zshrc. But it's throwing the command not found error for rbenv every time I start a new terminal. But rbenv works if I type it in manually, it only breaks when I start a new terminal. So in order for me to set a specific version for ruby, I need to run eval "$(rbenv init - zsh)" manually every time instead of relying on the terminal itself to run it automatically.
PS: I installed rbenv with Homebrew.
I have this line eval "$(rbenv init - zsh)" in my .zshrc.
The line should be after the rbenv binary location is loaded to the PATH environment variable.
Example:
export PATH="/home/someusername/.rbenv/bin:$PATH"
eval "$(rbenv init - zsh)"

I read a few Stack Overflow posts on a similar question, however, I cannot seem to fix my issue.
How do I get ruby --version to match the rbenv version?
rbenv version
2.6.5 (set by /Users/user/rubyonrails/lists/.ruby-version)
ruby --version
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
When I run
rbenv init
# Load rbenv automatically by appending
# the following to ~/.bash_profile:
eval "$(rbenv init -)"
I read a few other questions on Stack Overflow and modified my bash_profile accordingly, however it has not remedied the faulty rbenv init command.
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
export PROJECT_HOME=$HOME/Django
source /usr/local/bin/virtualenvwrapper.sh
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
Only add these lines on your .bashrc
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
later use this command $ rbenv install version-ruby
and for switch use $ rbenv global version-ruby
(replace version-ruby for the number of the version.)
When switching from bash to zsh, I looked up how to resolve an issue with my rbenv folder not being used correctly by zsh and found this:
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshenv
$ echo 'eval "$(rbenv init -)"' >> ~/.zshenv
$ echo 'source $HOME/.zshenv' >> ~/.zshrc
$ exec $SHELL
I ran all of these and seem to be using the correct rbenv folder now, but I get this error message whenever I open a new iTerm window:
/Users/myname/.zshenv:2: command not found: rbenv
What am I doing wrong? Any help would be very appreciated.
You need to add two things to your PATH.
First rbenv itself and second the ruby shims.
Part 1 rbenv
Installation
Homebrew
If you installed rbenv with brew,
then the rbenv executable should be linked to /usr/local/bin/rbenv.
See homebrew installation documentation for details.
Please add /usr/local/bin to your path PATH, if it is missing.
# in ~/.zshrc
export PATH=/usr/local/bin:$PATH
Github Checkout
If you install rbenv via a Github checkout, then the rbenv executalbe should be stored in ~/.rbenv/bin.
See github installation documentation for details.
Please add ~/.rbenv/bin to your path PATH, if it is missing.
# in ~/.zshrc
export PATH=$HOME/.rbenv/bin:$PATH
Verfiy
Please verify that rbenv is in your path by calling which rbenv.
The installation path should be returend.
Part 2 shims
Add the ruby shims to you path.
# in ~/.zshrc
eval "$(rbenv init -)"
Instead of the eval "$(rbenv init -)" command you can also add the shims folder directly.
# in ~/.zshrc
export RBENV_ROOT=$HOME/.rbenv
export PATH=$RBENV_ROOT/shims:/versions:$PATH
Part 3 rbenv doctor
You might also run the rbenv-doctor script mentioned here,
to check your installation.
I had the same problem...
when I ran ruby or rbenv, I got this error "command not found"
try this:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshenv
echo 'eval "$(rbenv init - zsh)"' >> ~/.zshenv
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.zshenv
I had this same error. I could run which rbenv and rbenv just fine, but no matter what I would get command not found: rbenv. The issue was that I had eval "$(rbenv init -)" in my ~/.zshenv and not my ~/.zshrc file. You may still have the path to rbenv be added to $PATH within ~/.zshenv for it to work.
I'm trying to install ruby in terminal via homebrew.
So far I've entered:
brew install rbenv
and then I rain
rbenv init
after the command was run I received
# Load rbenv automatically by appending
# the following to ~/.bash_profile:
eval "$(rbenv init -)"
finally I entered:
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
I restarted my terminal per instructions and then received
rbenv: no such command `init-'
at the top of my new terminal.
error messages: rbenv: no such command `init-'
expected messages: nothing, blank terminal
The default shell (Bash before macOS 10.15) on macOS is a login shell. Only .bash_profile is used in initialization by default.
You need to put eval "$(rbenv init -)" into ~/.bash_profile but not ~/.bashrc.
Bash init files
login mode:
/etc/profile
~/.bash_profile, ~/.bash_login, ~/.profile (only first one that exists)
interactive non-login:
/etc/bash.bashrc (some Linux; not on Mac OS X)
~/.bashrc
non-interactive:
source file in $BASH_ENV
Check the path of the red line for an interactive, login shell on macOS.

We are trying to run rbenv on El-Capitan 10.11.6. When we try to run rbenv command in the terminal we got the following error message:
command not found
We googled how to solve that issue and one possible solution is to add the "rbenv" to the system PATH, we followed the steps stated in this link. When we run the "$PATH" to check whether or not the rbenv path was added properly into the system PATH, we got the the same result:
command not found
The result of "$PATH" command is:
qwe-Mac-mini:~ amrbakri$ rbenv
-bash: rbenv: command not found
qwe-Mac-mini:~ asd$ echo $PATH
/Users/asd/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/MacGPG2/bin
Can you please tell me how to add the path of rbenv properly? And what did I do wrong in the previous steps so that I can fix it.
rbenv isn't a normal command if you've installed it correctly:
$ type rbenv
rbenv is a function
. . .
According to Homebrew on Mac OS X:
You'll only ever have to run rbenv init once.
That's a bit misleading because the result of running the command is:
$ rbenv init
# Load rbenv automatically by appending
# the following to ~/.bash_profile:
eval "$(rbenv init -)"
So you need to manually add eval "$(rbenv init -)" to some file that bash will source on startup. For most people ~/.bash_profile is the right place.
I notice the commands you listed seem to be run from two different users: amrbakri and asd. Combined with the question's use of "we", I wonder if there might be a problem with the environment being set correctly for one user, but not the other. Can you try using just one user?
If you are running from a non-interactive shell (such as in a crontab), you might need to add eval "$(rbenv init -)" to the startup script.
I following the instructions about "bash" command, then do the "eval" operation.
I'm in MacOS 11.2.3, in your .bash_profile, add the two lines.
export PATH="$HOME/.rbenv/bin:$PATH"#this is the required step for my mac
eval "$(rbenv init -)"

Tried to install something via terminal and got sucked into a rabbit hole and accidentally deleted some shit (incl. Ruby & rbenv). Now whenever I open terminal it automatically feeds me this:
-bash: promlexport: command not found
-bash: rbenv: command not found
-bash: rbenv: command not found
-bash: rbenv: command not found
-bash: rbenv: command not found
I get that rbenv isn't working right now, but wtf is promlexport? I've googled it and literally 0 relevant searches come up… I'm working on a mac using the beta OS X Yosemite.
This is my .bash_profile (if that means anything to you — sure doesn't to me):
function proml {
case $TERM in
xterm*)
TITLEBAR='\[\0033]0;\u!\h:\w\007\]'
;;
*)
TITLEBAR=""
;;
esac
PS1="\u: \p\e[32m\1\W\[\e[0m\]l\n\[\e[0.31m\]❤️ \[\e[0m\]"
}
promlexport PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
PS – Might this be fixed when I update to the public OS X Yosemite?
I deleted the following from my .bash_profile:
promlexport PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
Of course, it fixed everything. Instead of trying to reinstall rbenv, I successfully installed rvn. Definitely a "duh" moment, but more importantly, a learning one.
