Asked 17/11, 2019 at 0:11 Answered 15/6 at 8:33

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.

Try removing rbenv and reinstalling from scratch. – Guinness 17/11, 2019 at 10:31

You shouldn't need the last line; .zshenv is sourced automatically before .zshrc is. – Chitwood 17/11, 2019 at 14:55

Are you sure rbenv is, in fact, in $HOME/.rbenv/bin? – Chitwood 17/11, 2019 at 14:56

@Hustler did any of the comments or my answer help you? Can you please give us feedback or accept the answer? – Sulfonal 19/12, 2019 at 6:29

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.

Funnily enough, I skipped straight to the brew doctor script curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash and it identified the one thing I had missed, saving a lot of time – Adena 8/6, 2020 at 9:35

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 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
