Ruby/Rbenv for Jekyll Github Blog (MacOS)

1. Install Rbenv with Brew

brew update
brew install rbenv ruby-build

#check which versions are available
rbenv install -l

#install the specific version
rbenv install 2.6.10 (&& rbenv rehash)

#after installation
rbenv versions

* system	
  2.6.10
 
# if asterisk is before system, then command the line below to switch it. 

rbenv global 2.6.10

If you get the error indicating FilePermissionError below, then please try to add path.  

# open a vim 
vim ~/.zshrc

# set a path
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

# esc -> :w (to save changes) -> :q! (to exit)

source ~/.zshrc

 

Err) command 'source' returns the invalid message below. 

/Users/myname/.zshrc:export:2: not valid in this context: Code.app/Contents/Resources/app/bin

I'd recommend to remove the path of vscode in .zshrc and source ~./zshrc again. 

 

2. Install bundler

gem install bundler

output

3. Install jekyll

3-1. install nodejs as jekyll v2 requires it. 

brew install nodejs

3-2. install jekyll 

sudo gem install jekyll (full installation)
sudo gem install jekyll --no-rdoc --no-ri (w/o docs - fast installation)

output

3. check if jekyll has been installed successfully

jekyll -v
