При появлении ошибки (после запуска artisan):

 Signals are not supported. Make sure that the "pcntl" extension is installed and that "pcntl_*" functions are not disabled by your php.ini's "disable_functions" directive.
 

необходимо зайти в настройки web сервера (php.ini) и закомментировать строку:

; disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,exec,system,passthru,shell_exec,proc_open,popen

вот именно поставить ; в самом начале строки!
