我在我的项目中安装了angular2-recaptcha(https://github.com/xmaestro/angular2-recaptcha).
我添加了systemjs.config.js:
System.config({
map: {
'angular2-recaptcha': 'node_modules/angular2-recaptcha'
},packages: {
app: {
format: 'register',defaultExtension: 'js'
},'angular2-recaptcha': {defaultExtension: 'js',main:'index'}
}
});
index.html的:
但我在浏览器控制台中收到此错误:
Uncaught ReferenceError: System is not defined

compiler.es5.js:15996 Uncaught Error: Unexpected module 'ReCaptchaModule' declared by the module 'AppModule'. Please add a @Pipe/@Directive/@Component annotation.

请帮我!我的错误在哪里?
最佳答案
您需要加载SystemJS库,而不仅仅是配置:

此外,不推荐使用系统使用,使用SystemJS whereSystem是全局对象,例如,而不是System.import useSystemJS.import.
