Laravel error - Class setEventDispatcher does not exist - laravel

Short version
I'm getting this error, when I run php artisan serve and visit my home page:
ReflectionException (-1)
Class setEventDispatcher does not exist
Details
Laravel version: 5.6.39
Environment: local
OS: macOS Mojave 10.14.2
It started, when I got an error using npm (in another project), so I reinstalled Node (this way).
After doing that, then this project (in question) couldn't be started. I was getting this error, when running php artisan serve:
dyld: Library not loaded: /usr/local/lib/libpng16.16.dylib with anything php related
Referenced from: /usr/local/bin/php
Reason: image not found
That error was resolved by updating and upgrading brew.
Then I was capable of starting the project (php artisan serve). But when I visit the home page, this error was shown:
ReflectionException (-1)
Class setEventDispatcher does not exist
If I follow the stack trace, then I can see that it was this line (from my homeController) that triggered the error:
if( ! Auth::check() ){
return view( 'pages.home' );
}
If I commented that out, then the same error occured from another place, where the Auth-module was being used.
Here's the stack trace:
Does anyone know how to resolve this? I can't find any promising results on Google, - and I have no idea why this happens... :-/
Addition1
I tried composer clear-cache and deleting the vendor-folder, and then doing a composer install and the problem still occured.
I also checked my Service Providers, as Marcus suggested, - but I don't really know what to look for in there. It all looks pretty regular (no fancy if-statements or anything).
Addition2
I realized, that I couldn't connect to my database using Sequel Pro. And it was because Brew had updated my MySQL-version from 5.5 to 8.0.
That was resolved by doing something along these lines (I did a bunch of stuff, so I might be missing a coulple of steps):
brew unlink mysql
brew install mysql#5.7
brew switch mysql 5.7.21
brew link mysql
and I could then verify the version with mysql --version. I also had some permission issues with that MySQL-version-change, but I'm emitting that, so this doesn't get too long.
Addition3
I tried disabling the Laravel Debugbar (by deleting it from composer.json, deleting composer.lock and vendor and then running composer install). And that fixed it!! ... But!
When I later tried to install Barryvdh's IDE Helper, then the exact same error came back!?
I performed these three steps, to install the IDE Helper (and re-introduce the error):
Run this command from the root of my directory: curl https://gist.githubusercontent.com/barryvdh/5227822/raw/4be028a27c4ec782965bb8f2fdcb4c08c71a441d/_ide_helper.php -o _ide_helper.php
Add these lines to app/Provider/AppServiceProvider.php:
...
if ($this->app->environment() !== 'production') {
$this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
}
Run this command: composer require --dev barryvdh/laravel-ide-helper
So I'm back at this error:
ReflectionException (-1)
Class setEventDispatcher does not exist
... The stack trace is identical to the one shown previously (sprung from Container.php).

Tried every solution, none of them worked.
Finally, i realised that when trying to upgrade php to 7.3.3 it was infact a network error that caused the fail. Read the logs, tried again, restarted valet and tried again.
It works now.
Upgrading to 7.3.3 was the solution indeed.
Thank you!

So this is what usually fixes it for me
Reinstall composer dependencies by removing vendor folder and composer.lock. Then run composer clear-cache and then composer install (this is usually the problem)
Check that all service providers are imported correctly in app.php under directory config
Make sure that your service providers are not importing something that does not exist, for example if you register a service provider in production but is only installed as dev:
if (env('APP_DEBUG')) {
$app->register(Barryvdh\Debugbar\LumenServiceProvider::class);
}

If you use valet, I solved it running
valet restart and all works fine.
cheers!

The fix for me was to update PHP to 7.3.3 and then restart valet. Apparently this was a bug with php 7.3
https://github.com/laravel/framework/issues/27052
Hope this helps

I got some idea... I've just run into this problem after reconfiguring my apache virtual host ports, so I restarted apache/httpd again, and the problem went away. Might it be related with the server environment?

I am facing the same issue in mac book pro. My system configuration is PHP 7.3, MySQl and I use SQL Pro. I have implemented all the above methods but nothing gets worked.
The issue is still a mystery for me but for temporary I have solved this issue using
artisan command as bellow.
php artisan serve
Its Allow me to run the project on http://localhost:8000
Hope this can help to solve this issue.

Try to restart PHP. When I reboot my Mac, then this happens. After restarting PHP everything starts to work.
sudo brew services restart nginx

How to fix "https://repo.packagist.org/packages.json does not contain valid Json"?

I've an issue with composer running on a vagrantbox (Centos 7), which started to just suddenly happen.
I've already tried manually running the command/solution mentioned on the link below but to no avail.
(To clarify, i'm using vagrant not docker, but it was the closest question i found to my situation. Most of the information i found are related to composer.json not being valid, but here is packagist.org/packages.json which, is currently valid)
Composer not working in docker container: "https://packagist.org/packages.json" does not contain valid JSON
Here are the details of the issue.
While running composer update on terminal i get:
composer update
[Seld\JsonLint\ParsingException]
"https://repo.packagist.org/packages.json" does not contain valid JSON
Parse error on line 1:
^
Expected one of: 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
And when running composer install also on terminal every package returns this:
Failed to download psr/cache from dist: "https://api.github.com/repos/php-fig/cache/zipball/d11b50ad223250cf17b86e38383413f5a6764bf8"
appears broken, and returned an empty 200 response
Now trying to download from source
When running composer config --global repo.packagist composer packagist.org
the results are now
composer update
Loading composer repositories with package information
[Composer\Downloader\TransportException]
Your configuration does not allow connections to http://repo.packagist.org/packages.json. See https://getcomposer.o
rg/doc/06-config.md#secure-http for details.
Any ideas why this started to happen, how can i fix it?
Could also be IPv6 related, if your provider/system is configured for IPv6 but has no valid IPv6 route out to the internet.
This happened to me, and doing
sysctl -w net.ipv6.conf.all.disable_ipv6=1 (as root), then trying composer again fixed the issue.
To permanently apply it, add the rule to /etc/sysctl.conf (or wherever your OS preferred is)
same problem here, since php updated to 7.2.17.
On a centos 7 with php 7.2.16 composer run just fine...
Rollback to 7.2.16 is for now the only solution found...
Edit :
Seems to be a symfony flex issue : https://github.com/symfony/flex/issues/484
I had the same problem. After days of searching, I found a solution. It seems a PHP problem. Try to comment a line of curl extension on php.ini. I am using php version 5.6.
extension=php_curl.dll
Type ; before the extension name, at least it will be like this:
;extension=php_curl.dll
I had the same issue try to install symfony twig bundle. I ran :
set http_proxy=
set https_proxy=
composer require symfony/twig-bundle
and it worked
I ran a composer global require laravel/installer simply upgrading laravel/installer according to Laravel https://laravel.com/docs/9.x/installation#the-laravel-installer and the error was resolved.
Simply Just check out your internet and it well be ok
in the XAMP i have done follwing changes
comment the follwing line
;extension=php_curl.dll
and it worked properly
My solution: connect to a vpn before running the command!
For me basically the problem was because my IP was from Iran. Connected to a vpn and it worked perfectly.
it will works when we run this command in console
composer config disable-tls true
I bypassed the problem by redirecting the output to /dev/null.
composer require symfony/orm-pack > /dev/null

Cannot install Laravel correctly

I followed all the instruction by installing composer and then Laravel. Also I did everything what was shown in laracast series for installing Laravel and composer.
BUT I have some problems and I cannot solve them:
I don't have Vendor folder in my Laravel app folder
I cannot launch command 'composer artisan' as it says that
[Symfony\Component\Console\Exception\CommandNotFoundException]
Command "artisan" is not defined"
"php artisan" also doesn't work
All the answer in the web I have already tried to resolve my problems but nothing worked for me
Please, tell me, how can I install Laravel correctly and use it without errors
Run composer install or composer update. This will create the vendor folder and download all the dependent modules as mentioned in the composer.json
I want to add some more details which are asked but not clearly answered.
You did not install the composer dependencies. Try composer install.
It is not composer artisan. If you execute that command, you say hey composer! run your artisan command. And it says "Command "artisan" is not defined."
It is php artisan. But if you don't run composer install, php artisan will not work either. Because you are missing Symfony Console Component in your project (not the one used by composer) as well as a complete Laravel installation. Both will also be installed by the composer install command.
Well. I've solved my problem. As I mentioned before I had tried all the answer in the web but nothing had helped me. So then I just deleted my laravel project and ran this command
sudo apt-get upgrade
After some time packages were upgraded and I created new Laravel project. And Laravel started working perfectly! So in any incomprehensible situation do apt-get upgrade :))

Has anyone got memcached to work on Laravel Homestead php7 box?

I loaded up Laravel/Lumen on the new Homestead php7 box and encountered this error:
FatalThrowableError in MemcachedConnector.php line 51:
Fatal error: Class 'Memcached' not found
Doing a phpinfo(); shows there is no memcached extension, but sudo service memcached status says memcached is running. It seems there is a php7 branch for memcached here: https://github.com/php-memcached-dev/php-memcached/tree/php7
Can anyone guide me on how to get it working in the new php7 Homestead VM?
EDIT: I just saw on the homestead install documentation that it says "Memcached (PHP 5.x Only)". Question still remains on how to get it working.
The work on php-memcached for PHP7 is not yet complete, not all tests pass; You can use everything but JSON serialization, I think.
There is no pecl support for PHP7, so right now you need to install extensions manually, like this:
git clone https://github.com/php-memcached-dev/php-memcached
cd php-memcached
git checkout php7
phpize
./configure
make
sudo make install
You must make sure that phpize is the PHP7 version. Additionally, if the php in your PATH is not PHP7, then the php-config in your PATH is not either, in this case you must pass --with-php-config=/absolute/path/to/php7-config to ./configure.
I have the same problem, but on Windows when using XAMPP. It seems memcached works for now with PHP 5+ only.
The problem for Windows users is to find the right .dll file named
php_memcache.dll (x86/x64 platforms).
I've spent hours looking for a solution, but nothing found. The very fresh description how to use memcached is here:
HOW TO: Install Memcache on XAMPP (Windows 7/8/10)
We still have to wait for PHP7+ implementation.

Laravel composer signal "11" error symfony osx

Anything I try to execute in Laravel, even minor files locally gives this message in composer:
[Symfony\Component\Process\Exception\RuntimeException]
The process has been signaled with signal "11".
Using OSX 10.7.5
Any help appreciated, as always.
For example :
composer update
typed in terminal retrieves the error message above
Make sure to check your composer cache folder has the right permissions for all files and folders.
If you ever ran composer as sudo or root then these cache folders could have the wrong root permissions.
Look at all the files and folders inside:
ll ~/.composer/cache/
Make sure you have proper permissions to write files in app/storage directory. And you can always use the following method of installation.
cd /your/app/directory
git clone https://github.com/laravel/laravel.git .
composer install
I got this error due to circular dependency on AppServiceProvider (when 2 services depend on each other). As the error does say much it took me a loooong time figure it out :/
Try:
Reinstall or upgrade PHP (Cli)
Make sure your .composer directory permission
This error message from laravel artisan is caused by Composer command error, you can try the same way from using command like:
composer dump-autoload -o
It should also cause error relating from aristan optimize command which be trigger from post-update-cmd" in composer.json.
In my case, the error is segment fault via Cygwin PHP so that I change to use XAMPP PHP to run it and it worked.
Try to run thin command
composer dump-autoload
I eventually solved this by employing a freelancer who was excellent and very knowledgeable.
First needed to update OSX with Maverick (free) - (I had to change my hard drive to do this!)
Then needed to download xcode
Composer should then function, you may need a new installation of laravel
Hope that helps someone!

Cant' get MongoDB PHP Extension to work

I've been following this tutorial to try to install the PHP MongoDB extension but unfortunately haven't been able to get it working.
http://www.marcwitteveen.com/tech/mac/installing-mongodb-on-a-mac-so-you-can-access-it-with-php/
I can access the collections in the terminal, the database is properly installed but I didn't manage to get the extension working.
I have the following problem:
Sinan-MBP:mongo-php-driver-master Sinan$ cd
Sinan-MBP:~ Sinan$ sudo pecl install mongo
pecl/mongo is already installed and is the same as the released version 1.4.1
install failed
I've been trying several times so that's probably why I get this message. However, even after adding "extension=mongo.so" to the php.ini, I can't use MongoDB in my PHP code.
Thank you for your help.
This is likely a case of modifying the wrong php.ini for the environment, or PHP not being able to find the mongo.so in its directory. If you have separate php.ini files for CLI and web environments, PECL might have installed the compiled extension to a different directory.
If you run through the installation docs, there are instructions for grepping extension_dir from php -i and ensuring that mongo.so is present in that directory. If your web environment has a separate php.ini file, then grepping output from php -i likely won't help. You may need to view phpinfo(); output through your web server and check for the extension directory there.
One additional test that PECL installation succeeded would be attempting to view reflection information for one of the driver classes from the CLI environment. You can do so with php --rc MongoClient, which should print info on the methods of the MongoClient class.
I don't know why it was not working but I found a workaround late last night.
I uninstalled the php extension and then installed it again and made sure the extension was loaded in the php.ini
sudo pecl uninstall mongo
sudo pecl install mongo
