Javascript 为什么umd SystemJS给我错误消息格式不正确

我只是想用systemJS创建模块化javascript并做出反应

在谷歌搜索它之后，会发现什么错误。这可能是因为XMLHTTPrequest，但我不知道如何在systemjs中设置它。 一切顺利。我可以使用systemJS运行react。但那个错误消息让我非常恼火

这是我的SystemJs.setup.js文件

在本地服务器上运行它。。。

请注意，在本地运行时，请确保从本地服务器或启用了本地XHR请求的浏览器运行。如果没有，您将收到一条错误消息

对于Mac上的Chrome，您可以使用：/Applications/Google\Chrome.app/Contents/MacOS/Google\Chrome——允许从文件访问文件&>/dev/null&

在Firefox中，这需要导航到about:config，在过滤器框中输入>security.fileuri.strict_origin_policy并将选项切换为false
