Did you upgrade from a previous version? Be sure to remove the alias you may have registered in you \config\app.php file.

No! I didn't upgrade... i've installed it few hours ago... there is only one entry in config/app.php in providers array:
Geocoder\Laravel\Providers\GeocoderService::class
http://i.prntscr.com/wyvVcbqrRTusvbQv64gZlg.png

I've executed following command:
php artisan vendor:publish --provider="Geocoder\Laravel\Providers\GeocoderService" --tag="config"

but it didn't work so I manually copy/paste geocoder.php in my config folder... and nothing else...

i've also tried removing that copied file... but didn't work...

removed cache also...

my php version:
PHP 5.6.31-1~ubuntu14.04.1+deb.sury.org+1 (cli)

I've completely removed toin0u from vendors directory then run composer update then i get following output:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 1 install, 0 updates, 0 removals
  - Installing toin0u/geocoder-laravel (1.1.2): Loading from cache
Package egeloen/http-adapter is abandoned, you should avoid using it. Use php-http/httplug instead.
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postUpdate
> php artisan optimize

The compiled services file has been removed.

That's expected output.

No! same Class geocoder does not exist error

Ignore my previous comment about php7. I got it confused with the upcoming release.

Try removing the geocoder config file, if you published it.

Hi @foziazahoor ... have you been able to solve this? This is most likely a configuration issue on your end, as we have not received any other reports like this, and I am unable to replicate it.

Hi, yup there is something wrong at my end... because it is working fine on my windows on php 7.0.9... i've upgraded to php 7.1 on my ubuntu as well... but still not working...

Bugger ... maybe start a new project and try it there? You can always run the unit tests to see if they work. They use their own configuration. If you're running on Ubuntu 14.x it might be an OpenSSL security issue, preventing the HTTPS requests from completing. Push your project to a production server on Ubuntu 16 (I use Laravel Forge), and it might work there. I've seen the old versions (prior to last week's 4.0 release) not work on local environments because of the OoenSSL issue, but work fine in production. Give that a shot.

I will close this for now, but feel free to open a new ticket if you find an issue in the end (maybe a conflict with another package, etc.).
