原因：内存太小

解决：扩展swap分区

编译时可确认：free -m 查看内存使用量

swap分区增加命令：dd if=/dev/zero of=/var/swap bs=1024 count=2097152 （2G）

创建swap文件： mkswap /var/swap
开启这个swap文件：swapon /var/swap，开启前需要给swap文件0600权限：chmod -R 0600 /var/swap

开机自动挂载：在/etc/fstab 文件追加：/var/swap swap swap defaults 0 0

2 repo sync时报错：
UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xe6 in position 0: unexpected end of data

解决：repo sync --force-sync
