Answer 1

你可能应该收到警告：

TfidfVectorizer

因为你在组件中有大写字母C：

tfidf_vectorizer = TfidfVectorizer(vocabulary=terms) # add your other params here

请尝试：

WARNING in ./src/app/Courses.Component.ts There are multiple modules with names that only differ in casing. This can lead to unexpected behavior when compiling on a filesystem with other case-semantic. Use equal casing.

Answer 2

我认为这对于一个组件来说已经足够了。你能在浏览器的日志中显示你的错误吗？在Angular2 +中，您应该使用ng generate component componentname创建一个组件，请参阅here。
