Answer 1

I had a similar issue when trying to run composer update and none of the solutions above had worked. It turns out I had 2 require sections in my composer.json which is actually wrong.

"require": {
    "laravel/framework": "4.1.*"
},
"config": {
    "preferred-install": "dist"
},
"minimum-stability": "stable",
"require": {
    "barryvdh/laravel-ide-helper": "1.*",
    "zizaco/confide": "3.2.x",
    "laravelbook/ardent": "dev-master",
    "zizaco/entrust": "dev-master"
},
"require-dev": {
    "way/generators": "2.*",
    "fzaninotto/faker": "1.3.*@dev"
}

Combining the two as below solved my issue.

"require": {
    "laravel/framework": "4.1.*",
    "barryvdh/laravel-ide-helper": "1.*",
    "zizaco/confide": "3.2.x",
    "laravelbook/ardent": "dev-master",
    "zizaco/entrust": "dev-master"
},

If you still have a problem, try deleting the composer.lock and the vendor directory and run

mv ~/.composer/cache ~/.composer/cache.bak

To clear the composer cache and finally run

sudo composer install

This should solve the issue.
