Question

运行merng命令时出现此错误：

AppData\Roaming\npm\node_modules\mern-cli\lib\commands\generate.js:43
blueprints.forEach(function (b) {
           ^

TypeError: Cannot read property 'forEach' of undefined

问题是什么？

我发现，由于merng需要arguments导致了错误。像merng module <moduleName>一样，这将创建一个模块。

blueprints.forEach（function（b）{^ TypeError：无法读取未定义的属性'forEach'
