You have to install required packages by running composer install command.

When I run composer install within ~/.composer I get. 'Loading composer repositories with package information' 'Installing dependencies (including require-dev) from lock file' 'Nothing to install or update' 'Generating autoload files'

Then I get the same errror.

You have to run it from the root of your project. Where the composer.json is. (I guess it is /home/vagrant/Code/learning-laravel-5)

It will download every packages required for laravel and install them in the vendor folder. Then it generates an autoload.php file that is used by laravel in order to autoload all the classes.

Running composer install in the root of the project (on vagrant box) worked. Thank you! Follow do I need to do this for every subsequent new L5 app? Thanks!

Yes you have to do this for every laravel app.

By default the /vendor/ folder is not stored in git and is not included when you pull it in with composer/zip etc. This is your personal app's package directory.

running composer install inside my root folder, I get a problem with laravel/framework requires ext-mbstring. Any idea how to fix that? thanks

You will need to install it into PHP. It's an extension which is required.

I think it's in the php5-cli package.

Installing mbstring will depend on the operating system - Ubuntu/Debian/CentOS should have a php5-mbstring package you can install. OS X you'll have to recompile PHP. Windows ???

On Windows you just should uncomment "extension=php_mbstring.dll" string in php.ini - it ships by default all needed modules.

Also, you must uncomment ' extension_dir = "ext" ' in php.ini, to make php found it's own modules :/

I still get the error after running composer install on my vagrant project directory

OS X you'll have to recompile PHP

@deringer No, not necessarily.. you can install via homebrew with no need to recompile.

I just did a vagrant destroy and up and everything worked

Just Open Command Terminal and go to your project root directory and type composer install if already installed then type Composer Update
