Question

我在Digital Ocean下的Ubuntu托管（我是在两周前创建的）中出现内存错误：

root@ubuntu-boxBooking-Dev:/var/www/html/box-booking# lsb_release -d; uname -r; uname -i
Description:    Ubuntu 16.04.4 LTS
4.4.0-130-generic
x86_64

root@ubuntu-boxBooking-Dev:/var/www/html/box-booking# free -m
              total        used        free      shared  buff/cache   available
Mem:            992         325         562          35         104         518
Swap:             0           0           0

我安装了laravel 5.5应用程序。我从git提取更改，不得不安装干预/图像：

# composer require intervention/image 

Using version ^2.4 for intervention/image
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

mmap() failed: [12] Cannot allocate memory

PHP Fatal error:  Out of memory (allocated 586162176) (tried to allocate 20480 bytes) in /usr/share/php/Composer/DependencyResolver/Rule.php on line 66

root@ubuntu-boxBooking-Dev:/var/www/html/box-booking# 
root@ubuntu-boxBooking-Dev:/var/www/html/box-booking# lsb_release -d; uname -r; uname -i

我也尝试过：

# composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Removing doctrine/dbal (v2.6.3)
The following exception is caused by a lack of memory and not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details

我明白了没有配置交换上面的错误描述和上面的free命令中的0值。问题和如何解决？

还在Digital Ocean下安装Ubuntu托管我没有注意到任何交换选项...

Aslo可以重启系统解决问题吗？通常，我会重启在root下运行的ubuntu（我在笔记本电脑上使用kubuntu 18）：

reboot

在我的情况下还是在其他命令中必须运行？

谢谢！

到目前为止，添加交换似乎是唯一的解决方法。参考：https://github.com/composer/composer/issues/1898

过程：

df -h 
dd if=/dev/zero of=/swapfile bs=1M count=1024
sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
mkswap /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo 'echo "/swapfile  none  swap  defaults  0  0" >> /etc/fstab' | sudo sh

free -m
