i have problem with installing Rails on my server.
My server is not supporting GCC 4.7, i have only GCC 4.3.2.
I've read that unrecognized command line option "-flto" is a problem with GCC directly
When i install Rails, it shows me an error:
Installing sassc 2.2.1 with native extensions

Support told me, they can install 4.7 because they would need to rebuild almost half of libraries.
Is there easy way to fix this error?
What if i will exclude sassc from my installation? If this is a good idea, how can i do it?
I dont have this library in my Gemfile, can i delete those gems from my .gems folder? (i'm not that experienced in Ruby yet).
Thank you for your help
The option -flto is a link-time optimization flag. You do not need it. This flag is set in the sassc extconf.rb file, and can be disabled by doing:
export CONFIGURE_ARGS=--disable-lto
And then you can proceed to install Rails as normal.

Can anyone help me in solving this issue. I'd like to install it with sudo gem install cocoapods rather than brew
You should not use Apple's Ruby installation. That installation exists solely for internal use by Apple itself.
Since you have specified in your question that you want to use Apple's Ruby installation, I am afraid there is nothing that can be done to fix the problem.
If, on the other hand, you are willing to use a different Ruby installation (installed by hand, with Homebrew, with ruby-install, with ruby-build, with RVM, asdf, or any other way), then the problem should not present itself in the first place.
For more information, see for example

you need to install Xcode Command Line Tools。

How can I resolve this issue?
Versions
ruby : 2.2.1
rubyGem : 2.4.5
I was going through this very same issue.
Looked up the Git Repository for the Gem (HTTP_Parser) and found out the reason for my problem:
HTTP_Parser currently doesn't not support a Path with spaces
So I renamed my path and solved it.
To resolve attempt to add the devkit to Ruby like this:
Install Ruby+DevKit from RubyInstaller: Ruby Window Installers
Downloads
Check the "ridk install" checkbox at the end of the installer.
When RIDK runs, pick option 3 to install both MSYS and MINGW dev tools (make is provided with the MINGW stuff).
Open a fresh console (to get fresh environment variables), and rerun your gem or bundle command...and hope for the best.
I am using Rails 4. Bundle was working up until yesterday, when I had to reinstall Bundler because of a different error. Now, when I run "bundle install", a few gems are successfully installed and then I receive this error message:

I have no idea how to fix this. I have tried several solutions including:
-"rvm implode"
-"sudo gem update --system"
-"sudo gem update --system --no-user-install"
-"sudo chmod 755 /usr/local/lib/ruby/gems/2.0.0/gems"
-"xcode-select --install"
-running Disk Repair
I read a few things about making changes to the path and bash profile, but I am unclear on how to do that.
Thank you in advance! Already spent 2 hours trying to solve this.
Answered in this stack question : Insecure world writable dir /Users/username in PATH, mode 040777 when running Ruby commands
Your home folder should only be writable by you, not by anyone else. The reason gem is complaining about this is that you have folders in your PATH that are inside your (insecure) home folder, and that means that anyone who wants to could hack you by renaming/moving your .rvm folder and replacing it with an impostor.
To fix your home folder, run chmod go-w /Users/kristoffer. If there are any other insecure folders on the way to anything in your PATH, you should fix them similarly.
BTW, the reason that Disk Utility didn't repair this is that it only repairs files installed as part of the OS (see Apple's KB article on the subject). There is an option to repair home folder permissions if you boot from the install DVD and run Password Reset from the Utilities menu, but I'm not sure if it resets the permissions themselves or just ownership.
Update
Installing a new version of Ruby seemed to work. Previously I was using 2.0.0, and now I upgraded to 2.2.2. This seems to have made the issue go away.
I am trying to set up rails in my mac(Yosemite) machine. But when I do
gem install rails
I get the following error. Please help.

What am I missing here.??
I think rvm might be trying to use gcc 4.6, which doesn't work properly with rvm. I believe you can:
Uninstall gcc 4.6 (brew rm gcc46)
Pull the latest rvm (rvm get stable)
Retry gem install rails

I get the same error when I do 'gem install json....' as it suggests. I've installed the latest version of Xcode, with the command line tools. When I do:
which gcc
I get:
/usr/bin/gcc
I'm new to all this stuff really, so please try to keep things simple.
So, prior to XCode 5, there was a gcc-4.2 binary, which got removed in the upgrade.
I found this tutorial helpful in getting gcc-4.2 back and running with ruby. It assumes that you're using homebrew to manage packages on your Mac.
