npm ERR! code ETARGET
npm ERR! notarget No matching version found for ajv@undefined
npm ERR! notarget In most cases you or one of your dependencies are 
requesting
npm ERR! notarget a package version that doesn't exist.

Answer 1

使用装有 NPM 的 Yarn （已针对MEAN v2.0.1进行了测试）

MEAN安装

val a = if (condition) 2 else 6
val b = a * 2
