All browser targets in the browserslist configuration have supported ES module.
Therefore we don't build two separate bundles for differential loading.

环境是centos （垃圾）云主机

原因：

内存不够了

解决办法：

(env) [root@VM-20-16-centos vue3shower]# sudo fallocate -l 4G /swapfile
(env) [root@VM-20-16-centos vue3shower]# ll /s
sbin/     srv/      swapfile  sys/

(env) [root@VM-20-16-centos vue3shower]# npm run build

说明：

运行：

 sudo fallocate -l 4G /swapfile;

ls -lh /swapfile;

sudo chmod 600 /swapfile;

sudo mkswap /swapfile;

sudo swapon /swapfile;

sudo swapon -s;

free -m;

然后运行：

 sudo vim /etc/fstab 

把下面语句加入/etc/fstab文件末尾

 /swapfile none swap sw 0 0

再执行npm run build就能成功了。
