I'm trying to install the puma gem, but when I run

gem install puma

I get this error message:

Temporarily enhancing PATH to include DevKit Building native extensions. This could take a while... ERROR: Error installing puma: ERROR: Failed to build gem native extension.

Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/puma-2.6.0/ext/puma_http11/gem_make.out

Adding gem 'puma' to my Gemfile and running bundle install isn't an option, because that just doesn't work with any gem and gives me an error message (which is a separate issue, one that I've circumvented with the other gems I've used by installing them via gem install).

    It sounds like you might not have the openssl headers installed for your platform. Check out puma issue GH#202 for links to OpenSSL headers for Windows. Commented Nov 29, 2013 at 22:52

    I ran bundle update before bundle install and that solved the issue. I'm not sure if that was the only thing that helped, as I manually downloaded openssl and gem install puma -- --with-opt-dir=c:/RailsInstaller/openssl ruby -v -ropenssl -e "puts OpenSSL::OPENSSL_VERSION" Commented Feb 7, 2015 at 22:36

Came across very same issue.

sudo apt-get install libssl-dev

fixed it for me.

The OP is using windows, not linux.
But, this was helpful for me.

I ran bundle update before bundle install and that solved the issue for me.

I'm not sure if that was the only thing that helped, as I manually updated puma before that, using these steps:

  1. Checked which version of openssl Ruby is using by running ruby -v -ropenssl -e "puts OpenSSL::OPENSSL_VERSION"
  2. Downloaded the right openssl version from http://packages.openknapsack.org/openssl/openssl-1.0.0o-x86-windows.tar.lzma (got the link from https://github.com/hicknhack-software/rails-disco/wiki/Installing-puma-on-windows and edited it based on the output of #1).
  3. Extracted openssl using http://www.7-zip.org to C:\RailsInstaller\openssl
  4. gem install puma -- --with-opt-dir=C:/RailsInstaller/openssl

I think it was the manual update. I followed those steps and it worked. Note that it's important to use forward slashes (C:/RailsInstaller/openssl) instead of backslashes (C:\RailsInstaller\openssl).
This worked for me, but I had to go hunting for a 64-bit version of openssl as I'm using 64-but Ruby etc. For reference, I found it here: bintray.com/artifact/download/oneclick/OpenKnapsack/x64/…

Figured out the solution to the puma bundle. Followed directions from https://github.com/hicknhack-software/rails-disco/wiki/Installing-puma-on-windows

First you need to download:

  • DevKit compatible with your ruby version
  • OpenSSL Developer Package (contains header files and binaries)

And then:

  • Install DevKit, e.g. in c:\devkit
  • Unpack the OpenSSL Package, e.g. in c:\openssl (use 7Zip or PeaZip)
  • You need to copy the ddls from the bin directory (libeay32.dll and ssleay32.dll) to your ruby/bin directory.
  • Open a windows console
  • Initialize the DevKit build environment: c:\devkit\devkitvars.bat (except here, I used this in command prompt instead: ruby dk.rb init)

Now it’s possible to install the puma gem with the OpenSSL packages:

gem install puma -- --with-opt-dir=c:\openssl

This solution worked for me. Just in case someone need detail: gem install puma -v '2.9.1' -- --with-opt-dir=c:\openssl bundle install
ruby/bin already had the 2 dlls on my system, I tried to overwrite them with the ones in openssl and ruby started to complain about openssl support. Reverted to the original files and everything worked fine, thank you!

I think you hit issue #430 https://github.com/puma/puma/issues/430

Re-installing Ruby might help you as well as it closed this issue on GitHub.
