找不到预设的"es2015"相对于目录"web/static/js" [英] Couldn't find preset "es2015" relative to directory "web/static/js"

问题描述

我正在尝试构建一个流浪者服务器，用于涉足elixir和phoenix，但是在安装所有要求和依赖项之后，并且在运行mix phoenix.server时，出现以下错误:

I'm trying to build a vagrant server for dabbling with elixir and phoenix, but after installing all requirements and dependencies, and on running mix phoenix.server I'm getting the following error:

错误:"web/static/js/app.js"的编译失败.找不到相对于目录"web/static/js"的预设"es2015"；

error: Compiling of 'web/static/js/app.js' failed. Couldn't find preset "es2015" relative to directory "web/static/js" ;

我不确定这里的预设"的上下文，我希望更多经验丰富的凤凰用户会知道它的含义.

I'm not sure of the context of 'preset' here, I'm hoping a more seasoned phoenix user will know what it's getting at.

一些粗略的Google程序什么都没给我，除了可能与babel有关.

Some cursory Google's gave me nothing, other than it might be something to do with babel.

我只是尝试安装我认为是缺少的软件包sudo npm install babel-preset-es2015 -g，但它没有解决错误.

I just tried installing what I assume to be the missing package, sudo npm install babel-preset-es2015 -g, but it hasn't resolved the error.
