Looks like bundler is not configured correctly. :(

Or alternatively: it's not put in your $PATH.

[zeljkofilipin]

What should I have there?

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Is there something I have to add to $PATH?

By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/2.2.0/bin

You may want to add this to your PATH.

This formula is keg-only, which means it was not symlinked into /usr/local.

macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/ruby22/lib
    CPPFLAGS: -I/usr/local/opt/ruby22/include

==> Summary
🍺  /usr/local/Cellar/ruby22/2.2.5: 1,091 files, 17.9M

This version of ruby does not put ruby executable in /usr/local/bin.

$ ls /usr/local/bin/*ruby*
ls: /usr/local/bin/*ruby*: No such file or directory

It is in /usr/local/Cellar/ruby22/2.2.5/bin/

$ ls /usr/local/Cellar/ruby22/2.2.5/bin/
erb gem irb rake    rdoc    ri  ruby

I am confused. Why would Ruby 2.2 "cause all kinds of trouble" and 2.3 would not.

[zeljkofilipin]

What I guess is the most confusing to me is that until recently I could just brew install ruby and homebrew would make sure all binaries are in correct places. I did not have to add anything to $PATH. I do not mind configuring my system, but I am not sure what I need to do.

[zeljkofilipin]

Looks like ruby 2.4.0preview2 installs executables (including bundle) in /usr/local/Cellar/ruby/2.4.0-beta2_1/bin/bundle so adding that to $PATH should work.

[viktorbenei]

We see the same error on a completely new/clean El Capitan virtual machine

1. MacOS 10.11.6 installed
2. Xcode 8.0 installed
3. nothing else's changed/installed
4. installing brew with the one liner from http://brew.sh/
5. brew install ruby

No error anywhere, but after this gem install ANYTHING fails with the

ERROR:  While executing gem ... (Errno::EINVAL)
    Invalid argument

error.

We do this VM setup every week on Friday, and it worked last week.

[zeljkofilipin]

Looks like everything works fine if Ruby is built from source.

brew install ruby --build-from-source

[byCedric]

I can confirm that I solved the same issue with building from source as @zeljkofilipin said!

[erhudy]

I tried building from source after uninstalling (brew uninstall ruby and brew install ruby --build-from-source) to no avail. Same gem error as reported elsewhere on 10.11.6 with Xcode 8.0.

[zeljkofilipin]

I am not sure if it is relevant, but in debugging this I have:

• uninstalled homebrew
• deleted /usr/local/
• installed homebrew
• installed ruby from source

[holybit]

Same issue here. Is there a PR in the works?

[MikeMcQuaid]

Not yet. Feel free to beat us to it.

[sherzberg]

To confirm some above advice, this got me at least working for now:

gem uninstall -aIx
brew uninstall ruby
brew install ruby --build-from-source

$ which ruby
/usr/local/bin/ruby
$ ruby --version
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
$ gem --version
2.5.1
$ bundle --version
Bundler version 1.13.1

[MikeMcQuaid]

Have opened a PR to reproduce and start working on this in https://github.com/Homebrew/homebrew-core/pull/5480. I've reproduced it locally in a 10.11 VM (it's specific to there).

[p-groarke]

Unfortunately uninstalling gem + ruby and building from source isn't working here. Curious what the difference is. Personally I am running zsh vanilla...

[ilovezfs]

ENV.delete("SDKROOT") fixes this.

Where does one add this? Ty
