我花了相当多的时间玩，找不到任何关于这个问题的文档，我将诚实地说，我不知道足够的作曲家来解决这个问题。

我最近也有同样的问题。用--no-scripts标记运行composer。
composer update --no-scripts
这看起来像是你的编写器不工作，这通常是一个不兼容的PHP版本的特征。你的PHP是什么版本?Laravel要求>= 5.3.7
尝试更新PHP并通过发出以下命令重新运行composer
-add PHP5到apt-get库
sudo add-apt-repository ppa:ondrej/php5
-update your apt-get
sudo apt-get update
-重新安装PHP，确保用新版本覆盖当前版本!
sudo apt-get install php5-fpm php5-cli php5-cgi
重新启动nginx，然后在laravel目录下重新运行composer install
这是一个使用PHP单元在Ubuntu上安装Laravel 4的单行脚本http://irventu.com/installing-laravel-4-with-phpunit-composer/
我有同样的问题，这是为我工作:
- 备份composer.json
- 编辑comooser。并删除整个"scripts"块
- 作曲家安装
- 还原原始composer.json 作曲家更新
似乎我们没有在裸安装上运行artisan所需的所有依赖项，但是一旦所有的东西都被composer获取了，它就会运行得很好。
您正在尝试运行composer update而不是首先运行composer install吗?
当我试图在另一台PC上运行我现有的项目时，我遇到了这个问题。
一旦我拉下我的项目git，我试图做一个composer update而不是首先运行composer install，这给了我同样的问题。
一旦我运行了composer install命令，我的项目下载并安装了各种所需的依赖项，没有任何进一步的问题。
您可以尝试composer update而不是composer install。根据文档http://laravel.com/docs/installation有一个更简单的方法安装laravel通过运行命令sudo composer create-project laravel/laravel nameofproject
在运行phpinfo之后，我注意到"——disable-mbregex"是PHP配置的一部分，这意味着PHP没有使用mbregex扩展进行编译。我的错误日志显示"调用未定义的函数mb_regex_encoding"。
一旦PHP用mb_regex_encoding重新编译，这个问题就消失了。
