在新机器上启动Ember项目时出错：意外的令牌导入，未定义
我在2台电脑上安装了Ember js项目，但是在安装新电脑时遇到问题。
我这样安装：
git clone <repository-url> cd projectfolder npm install bower install ember serve 它编译，但在浏览器中，我看到这样的错误：
event-factory.js：3 – 未捕获的SyntaxError：意外的令牌导入
application.js：1 – 未捕获的ReferenceError：define没有定义
似乎与巴贝尔一些错误。
我有这样的package.json

我已经在一个月前成功安装了这个项目，但不知道为什么不在这台机器上启动…任何帮助表示赞赏。
你的问题很可能是使用^作为你的依赖关系。 当你做一个干净的安装时， ^ （插入符号）会把你的依赖升级到一个主版本。 例如，如果你对一个插件的依赖是让我们说1.2.0 ，你使用^1.2.0并有一个新的版本可用1.3.0 ，你会得到这个新的主要版本。 如果你使用~ （tilda）而不是^ ，那么你将不会得到1.3.0但是如果可用的话1.2.2 。 为了使用确切的版本，以便在执行干净的npm install时不会改变依赖关系，可以在依赖关系定义中删除caret和tilda。
为了弄清楚哪些依赖过时，可以使用npm outdated 。
