MacOSX Ruby installation, GitHub.io and Jekyll

Under construction. Do not use.

Ruby installation on MacOSX is not clean...these are the steps I had to take to get it to work. There are all sorts of paths in packages such as Anaconda which conflict with the paths to packages installed by Brew which are required for the installation of Ruby. Thanks to the GitHub, stack overflow, and superuser posts I was able to install Ruby in the end.

$ xcode-select --install

0. brew unlink openssl
1. brew uninstall --ignore-dependencies openssl
2. Repeat number 2 until all deps are gone
3. brew install openssl
4. Follow post install instructions:

If you need to have this software first in your PATH run:

  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:

    LDFLAGS:  -L/usr/local/opt/openssl/lib

    CPPFLAGS: -I/usr/local/opt/openssl/include

For pkg-config to find this software you may need to set:

    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

$ export LDFLAGS=" -L/usr/local/opt/openssl/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl/include"
$ export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

"I'm not sure I installed rbenv and a ruby version correctly"
Yep, sure it can be tricky.

1. sudo xcode-select --install
2. Install rbenv with brew install rbenv
3. Add eval "$(rbenv init -)" to the end of ~/.zshrc or ~/.bash_profile
4. Install a ruby version rbenv install 2.3.0
5. Select a ruby version by rbenv rbenv global 2.3.0
6. Open a new terminal window
7. Verify that the right gem folder is being used with gem env home (should report something in your user folder not system wide)

"I want to use bundler and rbenv together"
Perfect match!

1. Make sure you installed rbenv correctly ☝️
2. Select a ruby version locally for the folder you are located in e.g. rbenv local 2.3.0 (this creates a file called .ruby-version in the directory)
3. Verify that the right gem folder is being used with gem env home (should report something in your user folder not system wide)
4. Run gem install bundler
5. Run bundle install
6. Run on of your favorite gems defined in the Gemfile by bundle exec ... e.g. bundle exec fastlane

set -ex
brew update
brew install rbenv ruby-build
rbenv install 2.5.3
rbenv global 2.5.3
ruby -v
gem install jekyll bundler
rbenv rehash

if ! type rbenv | grep function; then
  echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
fi

set +x
echo "Done! Close and reopen your terminal"
