Try the following

gem install puma -- --with-cppflags=-I/usr/local/opt/openssl/include
bundle install


You can also specify the gem version, like the following:

gem install puma -v '2.11.3' -- --with-cppflags=-I/usr/local/opt/openssl/include


gem install puma

ERROR: Failed to build gem native extension

gem install puma -v '2.11.2' -- --with-opt-dir=/usr/local/opt/openssl

gem install puma -v '3.6.0' -- --with-opt-dir=/usr/local/opt/openssl

I'm on OS X 10.12.4 and the comment @mahi added worked for me:

gem install puma -v '3.6.0' -- --with-opt-dir=/usr/local/opt/openssl


I had similar issue on OSx El Capitan. In order to fix the issue I had to do:

brew install openssl
brew link --force openssl


Warning: Refusing to link: openssl Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew's openssl. Instead, pass the full include/library paths to your compiler e.g.: -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

I've run into a similar error under Mac OS X 10.10.

Details in the mkmf.log showed that this was due to:

Agreeing to the Xcode/iOS license requires admin privileges, please
re-run as root via sudo.

Which was caused by the installation of a new version of Xcode.
This was easily solved by accepting the Xcode license from Apple:

sudo xcodebuild -license


Hope this might help someone in the future ;-)

It could be an open ssl error

gem install puma -v 2.11.2 -- --with-opt-dir=/usr/local/opt/openssl


When using bundler and homebrew:

$ bundle config build.puma --with-cppflags=-I$(brew --prefix openssl)/include
$ bundle install


I copied and adapted this answer from Lloeki here: https://stackoverflow.com/a/31516586/704499

I had to do this beforehand: sudo apt-get install libgmp3-dev

sudo apt-get install libgmp3-dev

sudo apt-get install libssl-dev

gem install puma -v '3.1.0'

sudo apt-get install libgmp3-dev

libssl1.0-dev installing helped to me. Try

apt-get install libssl1.0-dev


and then

gem install puma


apt install libssl-dev

The gem is looking for ssl libraries. So we have to provide the path to the lib containing the ssl lib

e.g. /usr/share/openssl

In my case the the ssl lib "libcrypto" was in /usr/local/lib. So let's pass /usr/local to it (excluding lib word).

For gem install

gem install puma -- --with-opt-dir=/usr/local

For bundle install

notice the name build.puma. where puma is the name of the gem.

The build config command adds the following to ~/.bundle/config

Run brew info openssl and follow the instructions there. Do not try to --force link the latest openssl with the one that comes installed with OSX by default. (0.9.8)

brew info openssl

--force

Specifically it'll ask you to add the Homebrew version of openssl (should be 1.0.2 as of this date) into your $PATH.
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

Note: Make sure to remove any export PATH lines from the bash_profile, since this line above exports it for you appending the rest of the $PATH variable to the end. To view the bash profile use vi ~/.bash_profile

export PATH

vi ~/.bash_profile

This fixed the problems for installing ruby gems that require compilation. (Puma in this case)

Have you tried

DISABLE_SSL=true gem install puma


Specify the version if you have version specific requirement like:

DISABLE_SSL=true gem install puma -v version_number
