Error while loading Angular 2 SPA

Answer 1

我有一个类似的问题，在我看来似乎是angular2-jwt加载js-base64。我似乎无法弄清楚如何纠正这个问题。但是，我也发现了这可能是相关的。 https://auth0.com/forum/t/angular2-jwt-unexpected-token-syntax-error-from-system-config/1807

您可能需要在system.config.js中为js-base64添加映射，例如：

var map = {
    ...
    'js-base64': 'node_modules/js-base64/base64.js'
    ...
};

如何解决Angular 2 - Base64 404资源未找到错误？
