According to the jekyll site, this is how you make a new website with jekyll:

~ $ gem install jekyll

~ $ jekyll new myblog

~ $ cd myblog

~/myblog $ jekyll serve

gem install jekyll didn't work, nor did sudo gem install jekyll:

└─>gem install jekyll

I also tried following the answer here, but that doesn't help. sudo apt-get install jekyll works. Even then, though, running jekyll new myblog returns this error:

└─>jekyll new myblog

Anyone know what's causing this?
