Looks like you're trying to install with an RVM version of Ruby. https://github.com/Homebrew...

A comment is error:

# Then to load mysql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Shoulde be "postgresql", not "mysql"

in "brew install rbenv ruby-build" you can add rbenv-gem-rehash and never rehash again :) this is shown in railsgirls but still have to ask Chris if it is any good

Sweeet! I'm going to start using this from now on. Thanks for sharing!

After yosmite posters has stopped working

Same here:

rake db:create

Would now be a good time to upgrade to Yosemite if we already have Rails 4 installed on Mavericks?

Yeah, you may run into a few problems, but upgrading Homebrew and possibly a recompile or two and you won't have hardly any troubles. I updated my Macbook Air during the beta and didn't have hardly any trouble.

Worked a treat for a newbie thanks

I am following this guide strictly to install ROR on OS X Yosemite. I have installed ROR successfully but stucked on Configuring GIT. Got error, please help me to go further. Here is the error GIST - https://gist.github.com/tec...

Just press ENTER when it asks you where to save the file instead of typing "cat" and a filename. It will default to the correct location for you. You can then use the "cat" command to grab the public key after it is finished. Make sense?

Worked great. Thanks!

There is one step missing in the "Configuring Git" section.
After adding the key at Github and before testing:

# start the ssh-agent in the background
eval "$(ssh-agent -s)"
# Agent pid 59566
ssh-add ~/.ssh/id_rsa

as described in https://help.github.com/art...

How can i install Rails 4 on Mac OS version 10.7.5

Reply

Your best bet is to probably try following these steps. Homebrew should take care of getting everything installed properly for you.

For OS X Yosemite, you may need to remove ~/.rbenv/plugins/ruby-build before 'rbenv install 2.1.5'. See: https://github.com/sstephen...

Great tutorial - thanks.

'gem install rails' took so long I thought it was broken. 'gem install rails -V' is useful as it shows what it's doing. Also, I ended up having to use 'sudo gem install rails -V', but that could just me my setup.

i keep on getting the error "open cat ~/.ssh/id_rsa.pub failed: No such file or directory.

Saving the key failed: cat ~/.ssh/id_rsa.pub." during the "configuring Git" part of the article. I don't know what to do. :(

I feel like I'm missing out on something, did I ever make that directory? Was I supposed to? How was I supposed to? I don't think I missed any steps.

Hello, Sorry. Place for expert but I am a beginner...
I did the installation of Ruby and Rails but it was a mistake. Please could you tell me how to remove it ? I have no idea... I can not remove anything from my $username.
In advance, many thanks.

CTRL + C !

Hello,
"gem install rails" didn't work without "sudo". When running "$sudo gem install rails", it prompts error message:

ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary

need configuration options...

I appreciate any advice. Thanks

Make sure you installed all the dependencies (specifically zlib). Also, you almost never want to use "sudo" with this configuration.

Try this

sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -- --use-system-libraries -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include
