typescript 导出导致“错误 TS2451：无法重新声明块作用域变量”

Question

经过很长一段时间的间隔后，我正在将一个“旧的打字稿项目”更新为节点等的现代版本。修复了一堆 linter 错误后，我收到了一个奇怪的错误：

TSError: ⨯ Unable to compile TypeScript:
src/frames/frame.ts:28:7 - error TS2451: Cannot redeclare block-scoped variable 'frames_1'.

28 const frames_1 = require("../frames");
         ~~~~~~~~

  src/execute/eval-pipe.ts:4:7
    4 const frames_1 = require("../frames");
            ~~~~~~~~
    'frames_1' was also declared here.

这显然是由于打字稿编译器从不同的导入语句创建非局部变量：

= 框架.ts

export {}
import * as _ from 'lodash'
import { MetaFrame, NilContext } from '../frames'

= eval-pipe.ts

export {}
import { Context, Frame, NilContext } from '../frames'

这怎么可能？我向每个文件添加了 

export {}

以确保所有内容都在模块范围内。我需要不同的配置吗？

= tsconfig.json

{
  "compilerOptions": {
    "declaration": false,
    "esModuleInterop": true,
    "lib": ["es6"],
    "module": "commonjs",
    "target": "ESNext",
    "moduleResolution": "node",
    "noImplicitAny": false,
    "outDir": "./lib",
    "preserveConstEnums": true,
    "removeComments": true,
    "skipLibCheck": true,
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "test/**/*-spec.ts"
  ]
}

==更新

如果按照建议，我删除了

"require": "ts-node/register"

从 mocha_opts 中，我得到了错误：

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/ernest/Developer/hclang/node_modules/chalk/source/index.js from /Users/ernest/Developer/hclang/src/execute/hc-eval.ts not supported.
Instead change the require of index.js in /Users/ernest/Developer/hclang/src/execute/hc-eval.ts to a dynamic import() which is available in all CommonJS modules.

这让我想知道这行

import chalk from 'chalk'

是否格式错误或没有被正确解释。

FWIW，这是我最终解决（那些）问题的配置文件。奇怪的是，有几个测试文件仍然给出奇怪的 .ts 错误，但我现在可以解决这些问题。

package.json（部分）

  "type": "module",
  "directories": {
    "lib": "./lib",
    "src": "./src",
    "test": "./test"
  },
  "files": [
    "lib"
  ],

tsconfig.json

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "outDir": "./lib",
    "rootDir": "./src"
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules"]
}

.mocharc.json

{
  "extension": ["ts"],
  "require": "ts-node/register"
}
