PHP Composer 更新“无法分配内存”错误（使用 Laravel 4）

php laravel composer-php laravel-4

我只是无法解决这个问题。

我正在使用Linode 1G RAM基本计划。尝试通过Composer安装软件包，它不让我。我的内存限制在 PHP 上设置为“-1.ini

我还能做些什么来安装它吗？

答案 1

看起来您的交换内存用完了，请尝试以下操作

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

正如@BlackBurn027在下面的评论中提到的，这个解决方案在这里描述

答案 2

作为此处的作曲家故障排除指南，这可能是因为VPS内存不足并且没有启用交换空间。

free -m

要启用交换，您可以使用例如：

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1

或者，如果上述方法不起作用，则可以尝试创建交换文件

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
