Trouble installing jekyll on macOS Sierra 10.12.6

Question

1. Tried the original method of gem install jekyll and I get this error:

   ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

2. Installed Xcode and command line tools. Then followed up with installing homebrew using this command:

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3. get this error after:

   Error: Failed to link all completions, docs and manpages: Permission denied - (../../../Homebrew/completions/zsh/_brew, /usr/local/share/zsh/site-functions/_brew) Failed during: /usr/local/bin/brew update --force

4. These are my ruby and gem version:

Did you try running the command with sudo ? for example sudo gem install jekyll bundler. This will ensure that you're running the command as an administrator.
