I only install it, and run it, and then I get this error.

BTW, how can I uninstall? just remove the code from my project?

Thanks.

this packages was made with an older version of jade. the jade files in your project need to be updated like so:

doctype html
html(lang="en")
  head
    title= pageTitle
    block content

@thebrianlopez I had fixed several days ago, but still thank you.
