[英]TypeError: SimpleSchema is not a constructor in Meteor 1.6 project
我正在為Meteor中的員工集合創建一個SimpleSchema,我在服務器控制台中收到錯誤“TypeError:SimpleSchema不是構造函數”。 我已經閱讀了SimpleSchema文檔,這個構造函數就在那里,我的代碼和它們的例子相同。 不確定為什么會出現這個錯誤。

謝謝你的協助。
您需要導入沒有大括號的包,因為它作為默認導出導出到公共:
import SimpleSchema from 'simpl-schema';
因此,你甚至可以這樣導入它:
import MyRenamedSchema from 'simpl-schema';
然后可以由另一個命名構造函數new MyRenamedSchema

為那些來到這里的人添加一個答案,並且他們的導入已經完全沒有卷曲。 似乎如果您的數據庫中已經有數據,這也會發生。
您需要在.meteor / packages中添加以下包以使用SimpleSchema構造函數。

aldeed:simple-schema
