找不到“merge-graphql-schemas”TYPESCRIPT 的声明文件答案

【问题标题】：could not find declaration file for 'merge-graphql-schemas' TYPESCRIPT找不到“merge-graphql-schemas”TYPESCRIPT 的声明文件

【问题描述】：

除非我删除 noImplicitAny，否则我无法编译 typescript

我得到了这个错误，我正在使用来自 npm 的 merge-graphql-schemas 库

    TSError: ⨯ Unable to compile TypeScript:
src/utils/genSchema.ts(1,44): error TS7016: Could not find a declaration file for module 'merge-graphql-schemas'. '/home/user/Documents/voting/node_modules/merge-graphql-schemas/dist/index.cjs.js' implicitly has an 'any' type.
  Try `npm install @types/merge-graphql-schemas` if it exists or add a new declaration (.d.ts) file containing `declare module 'merge-graphql-schemas';

在我的 src->types->merge-graphql-schemas.d.ts

声明模块“merge-graphql-schemas”；

我的 tsconfig 是这样的

    {
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "lib": ["dom", "es6", "es2017", "esnext.asynciterable"],
    "sourceMap": true,
    "outDir": "./dist",
    "moduleResolution": "node",

    "removeComments": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "strictFunctionTypes": true,
    "noImplicitThis": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "allowSyntheticDefaultImports": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true
  },
  "exclude": ["node_modules"],
  "include": ["./src/**/*.tsx", "./src/**/*.ts"]
}

我是不是应该专门做点什么？我将 lib 从 npm 更改为 schemaglue，即使它也没有类型，所以我做了同样的事情，但对于 schemaglue，我仍然得到相同的错误。也许我在 tsconfig 中遗漏了什么？

这就是我使用 merge-schema-graphql 的原因

    import { mergeTypes, mergeResolvers } from "merge-graphql-schemas";
import * as path from "path";
import * as fs from "fs";
import { makeExecutableSchema } from "graphql-tools";
import * as glob from "glob";

export const genSchema = () => {
  const pathToModules = path.join(__dirname, "../modules");
  const graphqlTypes = glob
    .sync(`${pathToModules}/**/*.graphql`)
    .map(x => fs.readFileSync(x, { encoding: "utf8" }));

  const resolvers = glob
    .sync(`${pathToModules}/**/resolvers.?s`)
    .map(resolver => require(resolver).resolvers);

  return makeExecutableSchema({
    typeDefs: mergeTypes(graphqlTypes),
    resolvers: mergeResolvers(resolvers)
  });
};

我遇到了同样的问题！我通过移动来修复它

import { fileLoader, mergeTypes, mergeResolvers } from 'merge-graphql-schemas'

到之后

import { graphqlExpress, graphiqlExpress } from 'apollo-server-express'
import { makeExecutableSchema } from 'graphql-tools'

我不完全确定为什么会发生这种情况，但我相信这是由于一些不稳定的依赖关系。

【解决方案2】：

这里是问题：https://github.com/okgrow/merge-graphql-schemas/issues/154

为简单起见，您可以创建一个global.d.ts 文件并放入以下声明：

declare module 'merge-graphql-schemas' {
  export function fileLoader(...args: any[]): any;
  export function mergeResolvers(...args: any[]): any;
  export function mergeTypes(...args: any[]): any;
}
