javascript - GraphQL 抛出语法错误

Question

我正在开发 GraphQL Node 教程，目前已完成第 7 步。

https://www.howtographql.com/graphql-js/7-subscriptions/

我的 datamodel.prisma 文件中的这段代码出现了一些语法错误:

directive @id on FIELD_DEFINITION
directive @unique on FIELD_DEFINITION
directive @createdAt on FIELD_DEFINITION
scalar DateTime

type Link {
    id: ID! @id
    createdAt: DateTime! @createdAt
    description: String!
    url: String!
    postedBy: User
    votes: [Vote!]!
}

type User {
    id: ID! @id
    name: String!
    email: String! @unique
    password: String!
    links: [Link!]!
    votes: [Vote!]!
}

type Vote {
    id: ID! @id
    link: Link!
    user: User!
}

但我仍然收到'User'类型[@6:1]尝试重新定义现有的'User'类型[@15:5]和'Link'类型[@24:1]尝试重新定义现有的'Link'类型[@6:5]。

我也不确定我是否正确声明了指令或标量，因为官方教程中缺少这一点。

任何人都可以就如何解决这些问题提供任何建议吗？

架构.graphql:

type Query {
    info: String!
    feed(filter: String, skip: Int, first: Int, orderBy: LinkOrderByInput): Feed!
}

type Feed {
    links: [Link!]!
    count: Int!
}

type AuthPayload {
    token: String
    user: User
}

type User {
    id: ID!
    name: String!
    email: String!
    links: [Link!]!
}

type Vote {
    id: ID!
    link: Link!
    user: User!
}

type Link {
    id: ID!
    description: String!
    url: String!
    postedBy: User
    votes: [Vote!]!
}

type Subscription {
    newLink: Link
    newVote: Vote
}

type Mutation {
    post(url: String!, description: String!): Link!
    signup(email: String!, password: String!, name: String!): AuthPayload
    login(email: String!, password: String!): AuthPayload
    vote(linkId: ID!): Vote
}

enum LinkOrderByInput {
    description_ASC
    description_DESC
    url_ASC
    url_DESC
    createdAt_ASC
    createdAt_DESC
}

今天早上我遇到了同样的错误，我感觉这与缓存有关。当我重命名变量时它就消失了。在您的情况下，将所有“Link”定义/引用更改为“LinkTwo”，然后查看错误是否消失。与“User”相同...将其更改为“UserTwo”。如果是这样，也许您可​​以稍后将它们重新命名。
