使用vue-cli 3打包时，出现了问题：

可是在本地打包时却没有发现这个问题，在运维脚本打包的服务器上却出现了，然后在github的某个库的issue上找到了答案：

Nice write up @pm-radu, also seeing this issue here.

It appears the two options for resolving it are to modify the project’s package.json on line 48 to specify a version of Node.js greater than 7.6 when support was added for async/await. Additionally the dependency opn is now called open and should be updated.

Alternately if maintaining support for the oldest versions of Node is a priority, line 24 could be modified to specify the last opn version without async/await which is 5.4.0.

服务器node版本是6,而async/await语法需node > 7.6，所以报错了。
