Deploy to gh-pages from a nested folder.

Trying to deploy from a inner folder to gh-pages, you must have the transpiled assets in the desired directory.

If you want to deploy from the dist folder you should commit it to gh-pages branch.

  • Run this git subtree push --prefix dist origin gh-pages
  • In the GitHub project Settings, down to Github Pages, and in Source branch select: gh-pages.

That's it

PG::ConnectionBad: could not connect to server in Rails

Trying to run a rails console in my development env, It has thrown this error:

PG::ConnectionBad: could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?

$ brew uninstall postgresql
