Setting Up Environments on New Mac

You should run `brew doctor' *before* you install anything.
Now type: brew help

Hi hujiaweibujidao! You've successfully authenticated, but GitHub does not provide shell access.

hujiawei-MacBook-Pro:~ hujiawei$ brew install python
Warning: A newer Command Line Tools release is available
Update them from Software Update in the App Store.
==> Installing dependencies for python: readline, sqlite, gdbm
==> Installing python dependency: readline
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/readline-6.
==> Pouring readline-6.2.4.mavericks.bottle.2.tar.gz
==> Caveats
...

Warning: /usr/local/share/python is not needed in PATH.
Formerly homebrew put Python scripts you installed via `pip` or `pip3`
(or `easy_install`) into that directory above but now it can be removed
from your PATH variable.
Python scripts will now install into /usr/local/bin.
You can delete anything, except 'Extras', from the /usr/local/share/python
(and /usr/local/share/python3) dir and install affected Python packages
anew with `pip install --upgrade`.

hujiawei-MacBook-Pro:eclipse_cp hujiawei$ brew install rbenv
Warning: A newer Command Line Tools release is available
Update them from Software Update in the App Store.
==> Downloading https://github.com/sstephenson/rbenv/archive/v0.4.0.tar.gz
==> Caveats
To use Homebrew's directories rather than ~/.rbenv add to your profile:
  export RBENV_ROOT=/usr/local/var/rbenv
...

brew update
brew install rbenv
brew install ruby-build
rbenv install 1.9.3-p0
rbenv rehash
rbenv global 1.9.3-p0  #建议增加这句修改系统全局的ruby版本
ruby --version  #查看系统ruby版本
cd <path-to-octopress>
gem install bundler
rbenv rehash    # If you use rbenv, rehash to be able to run the bundle command
bundle install

gem install bundler
rbenv rehash    # If you use rbenv, rehash to be able to run the bundle command
bundle install

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
    cloog
    isl
