but when i execute similar command in the same directory (new anotherName) without internet connection it doesn't work and the nest error message is shown
[GuzzleHttp\Exception\RequestException]

Is there a solution because i can't work online always?

Answer 1

When you use the laravel installer it fetches the latest version from the server. One solution would be to initialise a Laravel project, then add it to git version control and then when offline checkout the project to a new folder. You'd have to manually choose a new app key (I think). You will also not be able to composer require or npm install any new packages while offline.
Once you have created it though it should run offline (unless your views are sourcing assets from, say, bootstrap or jQuery CDNs).

Composer 2+:
COMPOSER_DISABLE_NETWORK=1 laravel new myapp
Troubleshooting:
Check your composer version: composer --version - you may have to update to the latest version with composer self-update;
Check you have a global cache: echo $COMPOSER_HOME - you may have to create a ~/.composer and set export COMPOSER_HOME="${HOME}/.composer" to your ~/.bashrc or ~/.zshrc - don't forget to close and open your terminal to apply the changes;
If you get this error https://repo.packagist.org could not be fully loaded (Network disabled, request canceled: https://repo.packagist.org/packages.json), package information was loaded from the local cache and may be out of date, the laravel packages are not in the global cache. Run the command with internet enabled to download the files.
