$ bundle
zsh: command not found: bundle

Question: why bundle command not found?

With $ gem content bundler I found bundle executable file:

$ /usr/local/lib/ruby/gems/2.3.0/gems/bundler-1.16.4/exe/bundle --version

Bundler version 1.16.4

Why bundle executable isn't in /usr/local/opt/[email protected]/bin?

I see Bundle command not found mac question, must I use rbenv? I can't just use brew install [email protected]?

More information:

$ brew --version
Homebrew 1.7.2-112-g0dc2c72
Homebrew/homebrew-core (git revision bc34; last commit 2018-09-02)

And :

$ brew info [email protected]
[email protected]: stable 2.3.7 (bottled) [keg-only]
Powerful, clean, object-oriented scripting language
https://www.ruby-lang.org/
/usr/local/Cellar/[email protected]/2.3.7 (15,093 files, 38.3MB)

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/[email protected]
==> Dependencies
Build: pkg-config ✔
Required: libyaml ✔, openssl ✔, readline ✔
==> Caveats
By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/2.3.0/bin

You may want to add this to your PATH.

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

For pkg-config to find [email protected] you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"

  • macOS comes with its own version of ruby as well, so bundler gem may be installing for one version and not the other. Check out using rbenv, it makes working with multiple versions of ruby easier. https://github.com/rbenv/rbenv – Hayden Sep 02 '18 at 22:45

I'd recommend using rvm or rbenv. otherwise you will end up with multiple rubies without any control on them and their different contexts.

It'll be very messy. You just hit the start of this mess!
