Installing compass on Linux Mint.
I ran into problems installing Compass on Linux Mint and wanted to share the solution I found.
I got this error on installation:
ted@ted-Lenovo-G770 ~ $ sudo gem install compass [sudo] password for ted: Building native extensions. This could take a while... ERROR: Error installing compass: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:4:in `<main>' Gem files will remain installed in /var/lib/gems/1.9.1/gems/ffi-1.9.8 for inspection. Results logged to /var/lib/gems/1.9.1/gems/ffi-1.9.8/ext/ffi_c/gem_make.out ted@ted-Lenovo-G770 ~ $
The issue ultimately was not having the dev tools installed. There is a package in Mint called ruby1.9.1-dev that needed to be installed first (as of 6/5/2015).
I still get the following error when checking the version, however.
ted@ted-Lenovo-G770 ~ $ compass -v --trace Errno::ENOENT on line ["25"] of /usr/lib/ruby/vendor_ruby/compass/version.rb: No such file or directory - /usr/lib/ruby/vendor_ruby/compass/../../VERSION.yml /usr/lib/ruby/vendor_ruby/compass/version.rb:25:in `read_version' /usr/lib/ruby/vendor_ruby/compass/version.rb:13:in `version' /usr/lib/ruby/vendor_ruby/compass/commands/print_version.rb:59:in `long_output_string' /usr/lib/ruby/vendor_ruby/compass/commands/print_version.rb:94:in `execute' /usr/lib/ruby/vendor_ruby/compass/commands/default.rb:46:in `execute' /usr/lib/ruby/vendor_ruby/compass/exec/sub_command_ui.rb:43:in `perform!' /usr/lib/ruby/vendor_ruby/compass/exec/sub_command_ui.rb:15:in `run!' /usr/bin/compass:30:in `block in <main>' /usr/bin/compass:44:in `call' /usr/bin/compass:44:in `<main>' ted@ted-Lenovo-G770 ~ $
I will update if and when I find the solution for this problem.
I don't recall now, but I have since discovered that compass is in the Software Manager..........
