Composer site errors?

My site is throwing these errors:

Warning: require(/home/bobrocke/public_html/ or/jakeasmith/http_build_url/src/http_build_url.php): failed to open stream: No such file or directory in /home/bobrocke/public_html/ ser/autoload_real.php on line 54

Fatal error: require(): Failed opening required '/home/bobrocke/public_html/ asmith/http_build_url/src/http_build_url.php' (include_path='.:/usr/local/php53/lib:/usr/lib/php:/usr/local/lib/php' ) in /home/bobrocke/public_html/ ser/autoload_real.php on line 54

What do I need to be doing to fix it?

It comes from this function:

It comes from this line:
function composerRequire28afe50b28cef70bede15e9cdc717d3b($file)
    require $file;

Looks like something has gone wrong with your composer vendor libraries. You could try removing the vendor folder and doing a bin/grav install again.

All fixed after installing a .dependencies file from the Atom GitHub repository and running bin/grav install. Thanks!
