You get that message if the file can not be read. So check the permissions on your files, in this case ./system/libraries/uri.php.

i did chmod 0777 URI.php
no luck

Where in your code do you get this error, because it mentions 'uri' in lowercase, while the file is called URI.php (uppercase), and the frontcontroller loads it as such.

On linux, filenames are case-sensitive, so uri.php is a different file from URI.php.
