使用composer时出现laravel安装错误

Question

我正在尝试安装laravel，非常确定我已经安装了mcrypt

me:~/public_html$ composer create-project laravel/laravel laravel-test
 Installing laravel/laravel (v5.0.22)
 - Installing laravel/laravel (v5.0.22)
Loading from cache

Created project in laravel-test
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of      packages.

Problem 1
- Installation request for laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16].
- laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.

Answer 1

sudo apt-get install php5-mcrypt

创建辅助symlink并启用模块：

cd /etc/php5/mods-available

ln -sf ../conf.d/mcrypt.ini .

php5enmod mcrypt

最后，重新加载apache2配置：

service apache2 reload

先试一下，然后运行上面的代码，因为laravel需要安装mcrypt php扩展。

Answer 2

这解决了我的问题

  sudo rm /etc/php5/mods-available/mcrypt.ini
  sudo apt-get purge php5-mcrypt
  sudo apt-get install mcrypt
  sudo apt-get install php5-mcrypt
  sudo php5enmod mcrypt
