错误：package.js是unifined

Question

我最近做了一些更新，并根据meteor的建议添加了一些软件包

你知道通常的If you notice problems related to these missing modules, consider running: meteor npm install ...

现在问题是我收到与以下内容有关的错误

当我点击查看哪一行导致问题时，它来自var EJSON = Package.ejson.EJSON;

我不知道这是什么因此我假设我在开发过程中从未搞砸过它。

任何见解都会受到赞赏......

编辑：我通过我的命令回过头来，当我添加meteor add ecmascript（解决了一个问题以打开另一个问题）时，这个问题就开始了。）

同样要求.meteor / packages

# Meteor packages used by this project, one per line.
# Check this file (and the other files in this directory) into your repository.
#
# 'meteor add' and 'meteor remove' will edit this file for you,
# but you can also edit it by hand.
