javascript - 在新机器上启动 Ember 项目时出错 : Unexpected token import, define is not defined

Question

我在两台计算机上都有现有的 Ember js 项目，但我在新计算机上安装时遇到问题。

我是这样安装的:

git clone <repository-url>
cd projectfolder
npm install
bower install
ember serve

它编译但在浏览器上我看到这样的错误:

event-factory.js:3 - Uncaught SyntaxError: Unexpected token import

application.js:1 - Uncaught ReferenceError: define is not defined

似乎是 babel 的一些错误。

我有这样的package.json

我在几个月前成功安装了这个项目，但无法弄清楚为什么没有在这台机器上启动...感谢任何帮助。

您遇到的问题很可能是使用 ^ 作为您的依赖项。 ^(插入符号)所做的是在您进行全新安装时将您的依赖项升级到主要版本。例如，如果您对插件的依赖是 1.2.0 并且您使用了 ^1.2.0 并且有可用的新版本 1.3.0，你会得到这个新的主要版本。如果您使用 ~ (tilda) 而不是 ^，那么您将不会得到 1.3.0，而是 1.2.2 例如，如果可用。为了使用准确的版本，以便在执行干净的 npm install 时您的依赖项不会更改，您可以在依赖项定义中删除插入符和 tilda。

为了找出您的哪些依赖项已过时，您可以使用 npm outdated。
