正如标题所述，我在 Next JS 应用程序中使用 Prisma 2。我有一个非常简单的架构：

  model User {
  id             Int       @id @default(autoincrement())
  firstName      String
  middleName     String?
  firstLastname  String
  secondLastname String?
  email          String
  role           String
  group          Group?    @relation(fields: [groupId], references: [id])
  groupId        Int?
  activity       Activity? @relation(fields: [activityId], references: [id])
  activityId     Int?
  createdOn      DateTime  @default(now())
  updatedOn      DateTime  @default(now())
}

model JobTitle {
  id        Int      @id @default(autoincrement())
  name      String
  createdOn DateTime @default(now())
  updatedOn DateTime @default(now())
}

model Group {
  id        Int      @id @default(autoincrement())
  name      String
  users     User[]
  createdOn DateTime @default(now())
  updatedOn DateTime @default(now())
}

model Activity {
  id    Int    @id @default(autoincrement())
  name  String
  users User[]
}

我email在 User 模型上添加了字段，并将groupIdandactivityId字段更改为可选的。我还将role字段的类型更改为String. 我运行prisma migrate并prisma up创建一个新的迁移并同步数据库（使用远程 heroku postgresql 数据库作为我的数据源）并且一切运行良好。没有错误。但是，当我尝试创建新用户时，出现以下错误：

An error ocurred:  PrismaClientValidationError:
Invalid `prisma.user.create()` invocation:

{
  data: {
    firstName: 'John',
    middleName: 'Edgar',
    firstLastname: 'Doe',
    secondLastname: 'Smith',
    email: 'john@email.com',
    ~~~~~
    role: 'ADMIN',
          ~~~~~~~
+   group: {
+     create?: GroupCreateWithoutUsersInput,
+     connect?: GroupWhereUniqueInput,
+     connectOrCreate?: GroupCreateOrConnectWithoutusersInput
+   },
+   activity: {
+     create?: ActivityCreateWithoutUsersInput,
+     connect?: ActivityWhereUniqueInput,
+     connectOrCreate?: ActivityCreateOrConnectWithoutusersInput
+   },
?   createdOn?: DateTime,
?   updatedOn?: DateTime
  }
}

Unknown arg `email` in data.email for type UserCreateInput. Did you mean `role`?
Argument role: Got invalid value 'ADMIN' on prisma.createOneUser. Provided String, expected RoleCreateOneWithoutUserInput:
type RoleCreateOneWithoutUserInput {
  create?: RoleCreateWithoutUserInput
  connect?: RoleWhereUniqueInput
  connectOrCreate?: RoleCreateOrConnectWithoutUserInput
}
Argument group for data.group is missing.
Argument activity for data.activity is missing.

Note: Lines with + are required, lines with ? are optional.

看起来该操作正在使用以前版本的架构，看它如何说电子邮件字段不存在并且该role字段不是字符串类型。此外，groupIdandactivityId字段仍按要求显示。我不知道是否有某种缓存。我已经尝试删除所有迁移并从头开始重新部署所有内容。我什至删除了heroku中的数据库并重新开始，但我仍然遇到同样的错误。

运行npm install（无需删除 node_modules）然后重新生成 Prisma 类型可以解决此问题。

由于npm i删除了旧的 Prisma 代，npx prisma generate将不得不从您的schema.prisma.

Ryan 关于为 Prisma 添加安装后脚本的评论也是一个不错的 QOL 改进。

编辑： 关闭和打开你的编辑器（在我的例子中是 VsCode）将修复红线错误。我认为扩展很难用新的变化来更新自己。这很痛苦，但如果其他解决方案没有，它确实有效。
