[SOLVED] Error executing $jekyll serve --watch --baseurl ""

Error executing $jekyll serve --watch --baseurl ""

I want to make a blog using Jekyll, so have made a public repository in my GitHub account and made gh-pages branch and set it to default branch and later deleted master branch . Also, I have made _config.yml file whose contents are as follows:

markdown:redcarpet 
baseurl:/amar
exclude:['readme.md']

when I want to turn on Jekyll , using this command:

$jekyll serve --watch --baseurl ""

I am getting this error:

dhcp-54-132:amar Amar$ jekyll serve --watch --baseurl " "
           WARNING: Error reading configuration. Using defaults (and options).

Solution

There needs to be a space for the options and its values

markdown:redcarpet

should be

markdown: redcarpet

and so on in _config.yml file
