安装lxml时gcc: internal compiler error: Killed (program cc1)的解决方法

在安装lxml时出现如下错误

gcc: internal compiler error: Killed (program cc1)

通过查看dmesg发现下述错误信息
[2517343.500178] Out of memory: Kill process 5051 (cc1) score 632 or sacrifice child
[2517343.501833] Killed process 5051 (cc1) total-vm:471664kB, anon-rss:326648kB, file-rss:0kB
[2517441.995124] systemd-journald[233]: Vacuuming done, freed 4194304 byte

看来主要问题是因为内存不足导致的，为解决该问题通过增加swap分区来解决，具体方法如下：

sudo mkdir -p /var/cache/swap/ sudo dd if=/dev/zero of=/var/cache/swap/swap0 bs=1M count=512 sudo chmod 0600 /var/cache/swap/swap0 sudo mkswap /var/cache/swap/swap0 sudo swapon /var/cache/swap/swap0
