Native extension error installing JSON gem
native, ruby, ruby-2.1, ubuntu
Solution
I imagine you'll need to install the ruby2.1-dev package, rather than ruby2.0-dev, if you're using Ruby 2.1. I've not used the Brightbox packages though, so I'm only guessing I'm afraid.
Problem
I've set up the Brightbox Ruby 2.1.0 apt package and encountering a native compilation error installing `json` package. ``` $ sudo gem install json -v '1.8.1' Fetching: json-1.8.1.gem (100%) Building native extensions. This could take a while... ERROR: Error installing json: ERROR: Failed to build gem native extension. /usr/bin/ruby2.1 extconf.rb mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h extconf failed, exit code 1 ``` I've installed `ruby2.0-dev` as mentioned here, but it puts the headers in a different folder (/usr/include/ruby-2.0.0/ruby, and copying them to /usr/lib/ruby/include didn't help). Any idea how to install this gem?
