报错解决: fatal: Out of memory, malloc failed (tried to allocate 947912704 bytes)

使用云服务器git clone某个项目时，遇到如下问题：

fatal: Out of memory, malloc failed (tried to allocate 2000000000 bytes)

百度后找到如下解决方法：

sudo mkdir -p /opt/temp
sudo dd if=/dev/zero of=/opt/temp/swapfile bs=1M count=1024
sudo chmod 600 /opt/temp/swapfile
sudo mkswap /opt/temp/swapfile
sudo swapon /opt/temp/swapfile```
