# How to install Ruby 2.0.0-p247 on Mac OSX 10.7+

## RVM:

```
rvm get stable && rvm reload
```

Firstly, the OpenSSL comes with your OSX 10.7+ is outdated, you need to get latest version

```
rvm pkg install openssl
```

Secondly, the readline library on OSX 10.7+ suffers UTF-8 issue in which method in UTF-8 is converted to characters under `irb`, the
fix is to use latest version

```
rvm pkg install readline
```

And you can install Ruby 2.0.0-p247 with:

```
rvm reinstall 2.0.0 --with-readline-dir=$rvm_path/usr --with-openssl-dir=$rvm_path/usr
```

Please note that `clang-425.0.24` that comes with Xcode successfully compile the source, should you bump into any compilation issue, you could try compiling it with `gcc-422`

## rbenv

Make sure your `ruby-build` is up-to-date:

```
cd ~/.rbenv/plugins/ruby-build && git pull
```

rbenv does not fetch fixed readline lib, thus you are required to install them manually with `brew`:

```
brew update
brew install readline openssl
CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" rbenv install 2.0.0-p247
```

## chruby + ruby-build

If you happen to use something simpler than rbenv and rvm, such as chruby, you can still use ruby-build to compile ruby into
your local `~/.rubies` folder with:

```
brew update
brew install readline openssl
CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" ruby-build 2.0.0-p247 ~/.rubies/ruby-2.0.0-p247
```

then insert into the top of your `~/.bash_profile` to use it by default:

```
chruby ruby-2.0.0-p247
```
