我是DigitalOcean的基本墨滴。

首先我按如下方式安装了composer

curl -sS https://getcomposer.org/installer | php

mv composer.phar /usr/local/bin/composer

然后我尝试按如下方式安装Laravel:

composer create-project laravel/laravel --prefer-dist

然后我收到以下错误:

Installing laravel/laravel (v5.1.4)
  - Installing laravel/laravel (v5.1.4)

Created project in /var/www/html/laravel
> php -r "copy('.env.example', '.env');"

我该如何解决这个问题?厌倦了在线搜索不同的解决方案,并没有任何工作。

这是因为缺乏记忆力。你需要设置一个交换文件,以便作曲家可以做到这一点:

sudo dd if=/dev/zero of=/swapfile bs=1024 count=512k

mkswap /swapfile

swapon /swapfile
