问题
I know that there bunch of questions out there but mine doesn't seems fit in any.
I am working on laravel. php artisan was working fine an hour before. After that i just created a controller, a model and few views blade.
Now artisan simply won't work and no error at all. Even php artisan --version won't show anything.
I DIDN'T do any major changes like composer install, or update or install any new package. Neither any server configuration. It was just basic coding on controller , model and views.
Not sure what is causing this. What could be the reason and how shall i start debugging it?
回答1:
Artisan is an integrated part of Laravel, meaning it's using a console Application instance to run a command, and it will stop execution for errors which may come from any part of your application.
Syntax errors can be a common culprit that will stop artisan from working, and if debugging is not enabled errors are not displayed (just logged) so you get no output when running a command.
To search for syntax errors, go to your project directory and try linting the entire directory by running this command:
find -L ./ -name '*.php' -print0 | xargs -0 -n 1 -P 4 php -l | grep "Errors parsing".
If any syntax errors are present, the command will output the first file that has an error, the line where it occurs and the error message.

In my case, there were no problems with files and syntaxes. But when I reinstalled the dependencies it worked.
composer install
run above command in your working directory and it worked.
