Prisma. Javascript to Typescript

Question

我正在使用带有Javascript的Prisma。它运行良好。升级到typescript后，我出现以下错误：GraphQLError: Syntax Error: Cannot parse the unexpected character ".".

// index.ts
const path = require('path')
const express = require('express')
const { importSchema } = require('graphql-import')
const { ApolloServer } = require('apollo-server-express')
const { Prisma } = require('prisma-binding')
const { makeExecutableSchema } = require('graphql-tools')
import resolvers from './resolvers'

const { directiveResolvers } = require('./directives')

const schema = makeExecutableSchema({
typeDefs: './schema.graphql',
resolvers,
directiveResolvers
})
const server = new ApolloServer({
debug: true,
schema,
formatError: error => error,
context: req => ({
...req,
db: new Prisma({
typeDefs: path.join(__dirname, './generated-schema.graphql'),
endpoint: 'http://localhost:4466/nacho/prod'
})
})
})
const app = express()
const port = 9000
app.listen({ port }, () => console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`))

// tsconfig.json
{
"compilerOptions": {
"target": "es5",
"moduleResolution": "node",
"module": "commonjs",
"sourceMap": true,
"allowJs": true,
"rootDir": "src",
"outDir": "dist",
"lib": ["es2016", "esnext.asynciterable"]
},
"exclude": ["test", "dist"],
"include": ["src/**/*"]
}

然后我运行tsc，它工作，然后运行node dist/index_server.js，我有这个错误：

throw (0, _syntaxError.syntaxError)(source, pos, unexpectedCharacterMessage(code));

检查'./schema.graphql'是否存在语法错误？

无论您使用什么IDE，都应该有一个用于读取graphql模式的插件，并且应该突出显示语法错误。
