错误:在Typescript中使用Thrift时，找不到名称‘Thrift

Question

我想在Nodejs项目中使用Thrift和Typescript，这是我遇到的错误

src/gen-js/myService.d.ts:9:12 - error TS2503: Cannot find namespace 'Thrift'.

10     input: Thrift.TJSONProtocol;
              ~~~~~~
src/gen-js/myService.d.ts:10:1 - error TS2503: Cannot find namespace 'Thrift'.

11     output: Thrift.TJSONProtocol;
               ~~~~~~
error TS2304: Cannot find name 'Thrift'.

...(more of the same)

src/gen-js/myService_types.d.ts:198:32 - error TS2304: Cannot find name 'Thrift'.

198   class StoreException extends Thrift.TException {
                               ~~~~~~
...(more of the same)

我已经安装了@types/thrift并设置了我的tsconfig.json，如下所示

{
  "compilerOptions": {
    "module": "commonjs",
    "esModuleInterop": true,
    "target": "es2017",
    "noImplicitAny": true,
    "moduleResolution": "node",
    "inlineSourceMap": true,
    "outDir": "dist",
    "alwaysStrict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "baseUrl": ".",
    "paths": {
      "*": ["node_modules/*", "src/types/*"]
    },
    "lib": [
      "dom",
      "esnext"
    ]
  },
  "include": ["src/**/*"]
}

看起来很好，对吧？仍然会遇到错误。你知道如何成功构建它吗？

附注:我使用的是Typescript 3.2、Thrift v0.11和@types/thrift 0.10.7

安装这些类型后，您仍然需要在引用它们之前导入它们。

编辑：

在查看了类型定义之后，它不是..理想的打字方式。如果使用通配符导入类型(第二个示例)，则还有一个嵌套的Thrift命名空间

import { Thrift, TJSONProtocol } from 'thrift';

const protocol: TJSONProtocol = // instance;

class StoreException extends Thrift.TException {}

或

import * as Thrift from 'thrift';

const protocol: Thrift.TJSONProtocol = // instance;

class StoreException extends Thrift.Thrift.TException {}
