When installing on OSX Yosemite 10.10.1 with Ruby 2.2.0p0 I get the following error.

gem install eventmachine -v '1.0.3'
Building native extensions. This could take a while...
ERROR: Error installing eventmachine:

You need to update eventmachine to 1.0.4 in order to make it work with Ruby 2.2.0 (#509).

[davidbegin]

+1 upgrading to 1.0.4 got rid of this bug for me.

[jaredcwhite]

Yay! Works. Glad this update was ready to go for the official Ruby 2.2 release.

[tmm1]

eventmachine 1.0.4 was released with ruby 2.2 compatibility

[wagnerads]

+1 upgrading to 1.0.4

[jayperryworks]

I'm actually still running into this exact issue with 1.0.7, running OS X 10.10.2, and LLVM v6.1.0. I'm using ruby 2.2.1 via RVM (tried it on 2.2.0 and had same issue).

I'm completely stumped -- any suggestions hugely appreciated. A friend running LLVM 6.0 under the same setup had no issues, so my only guess is the command line tools update?

[zeroed]

@jayperryworks if I may suggest... I've solved installing Xcode 6.3 (you can find it here) ... not only the Command Line Tools, though.

[jayperryworks]

Thanks @zeroed! I wonder if the full Xcode ships with newer stuff that trickles down to command line tools later. I only need event machine for Livereload, so I'll hold off a little while and see if an update comes out for GCC.

[skunkworker]

You might try installing the 10.10.2 / Xcode 6.2 command line developer tools. The 6.3 ones don't include the right headers in the right location.

[michaelbarton]

The suggestion by @skunkworker worked for me. I was having a similar problem, where event machine installed fine last week but not today. The current release date on CL tools 6.3 is April 9 so I assume that 6.3 was installed in a software update at the end of last week. I installed 6.2 and eventmachine successfully installs on OS 10.10.

[skunkworker]

@michaelbarton It seems as though a certain header file was not being installed on a fresh 10.10.3 install if you had never installed 10.10.2. If you install the 10.10.2 then the 10.10.3 tools it still seems to work.

[ssenge]

Yes, this works for me as well. Installing 6.2. from developer.apple.com/downloads (although 6.3. was installed via automatic update) solved the issue.

[jayperryworks]

Worked for me too! Brilliant. Cheers, all, much appreciated.

[plicjo]

Nice! Thanks!

[garettarrowood]

+1 as well!

[1ak31sha]

I am having trouble installing eventmachine 1.0.3,1.0.4, or 1.0.7. Cant bundle install because of this. i have ruby 2.2.2 and OSX 10.11.4. Does anyone know how to solve this? Much appreciated!

[sodabrew]

I am happy to help debug problems with either of the most current revisions of EventMachine, which are 1.0.9.1 and 1.2.0.1.

[1ak31sha]

Thank you! but actually i figure it out. needed to install eventmachine which required 'brew install openssl' and then 'brew link openssl --force', then uploaded the new gemfile.lock

[vassilevsky]

I had to bundle an old project today on macOS Sierra. It has eventmachine v1.0.3 in the Gemfile.lock. There is no reason to upgrade it at this point.

A basic bundle failed:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/vassilevsky/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/eventmachine-1.0.3 for inspection.

An error occurred while installing eventmachine (1.0.3), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.

I had configured Bundler before to use OpenSSL installed with Homebrew:

  bundle config
Settings are listed in order of priority. The top value will be used.
build.eventmachine
Set for the current user (/Users/vassilevsky/.bundle/config): "--with-cppflags=-I/usr/local/opt/openssl/include"

Apparently this did not help.

I decided to see what OpenSSL formula has to say about all this:

  brew info openssl
openssl: stable 1.0.2l (bottled) [keg-only]
SSL/TLS cryptography library
https://openssl.org/
/usr/local/Cellar/openssl/1.0.2l (1,709 files, 12.2MB)
  Poured from bottle on 2017-06-01 at 16:10:01
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/openssl.rb
==> Dependencies
Build: makedepend ✘
==> Options
--without-test
	Skip build-time tests (not recommended)
==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

I decided to set these environment variables and see if it makes a difference:

  LDFLAGS='-L/usr/local/opt/openssl/lib' CPPFLAGS='-I/usr/local/opt/openssl/include' PKG_CONFIG_PATH='/usr/local/opt/openssl/lib/pkgconfig' bundle

This totally helped! The bundle has been installed without errors.

Hope this helps the next googler ❤️

[kuangda]

Thank you! It fails to work well

@googya this is already fixed please update to EM 1.2.6 or newer.

@googya this is already fixed please update to EM 1.2.6 or newer.

yes, I know, there is no problem when installing 1.2.6 or newer. But my old project needs 1.0.4, how to deal it ? @sodabrew

[sodabrew]

The issue is resolved in a newer version of EM. There may be some workarounds in the relevant tickets in the issue tracker. But I strongly advise that you work through updating.

[googya]

ok, I will try, thanks for your advice, @sodabrew
