Temporarily enhancing PATH to include DevKit...
Building native extensions with: \'--with-opt-dir=c         


        

Answer 1

To give you a summary of things you need to do:

Download OpenSSL package for x64-windows (since you're using x64 version of Ruby): http://packages.openknapsack.org/openssl/openssl-1.0.0k-x64-windows.tar.lzma Extract the package, as indicated in several RubyInstaller posts Proceed again with gem installation and point to the directory where you extracted OpenSSL

The commands will be something like this:

C:\>mkdir C:\MyDir\x64-windows
C:\>cd C:\MyDir\x64-windows
C:\MyDir\x64-windows>bsdtar --lzma -xf openssl-1.0.0k-x64-windows.tar.lzma
C:\>gem install puma --platform=ruby -- --with-opt-dir=C:/MyDir/x64-windows

Answer 2

This worked for me (with x86 version), following these steps: 1.To install OpenSSL, I went here: https://www.tbs-certificates.co.uk/FAQ/en/openssl-windows.html. 2. Running windows cmd as administrator, I created the directory C:/OpenSSL-Win32. 3. Following the instructions from step 1, I went to https://www.openssl.org/source/ and downloaded the opensslpackage for x86 (openssl-1.0.1p-tar-gz) and extracted it via 7-Zip to C:/OpenSSL-Win32 4. Still as admin, ran C:>gem install puma --platform=ruby -- --with-opt-dir=C:/OpenSSL-Win32. Note: I was following the Hartl tutorial, and had specified gem 'puma', '2.11.1'. However, this method resulted in '2.14.0' being installed.
