I can’t read TypeScript code at all, but it seems that up to a certain point there was a bug in the LangChain library for TS that made installation difficult.github.com/langchain-ai/langchainjs[ERROR] Langchain in typescript can't find a bunch of modules!opened10:23AM - 04 Apr 23 UTCclosed04:02PM - 04 Apr 23 UTCadifyrquestionenv/packagingHi. I installed langchain for my Node Typescript project. When I try to run the…sample, I get the following errors in the terminal:

I did do `npm install -S langchain`. And I set all the parameters in the tsconfig.json & package.json to the recommended values.

Here is my package.json:
```json
{
  "name": "sandbox",
  "version": "1.0.0",
  "description": "NodeJS sandbox.",
  "main": "dist/index.js",
  "type": "module",
  "scripts": {
    "start": "node dist/index.js",
    "build": "tsc && npm run start"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "langchain": "^0.0.47"
  },
  "devDependencies": {
    "@types/node": "^18.15.11"
  }
}
```

And here is my tsconfig.json:
```json
{
  "compilerOptions": {
    "target": "ES2020",
    "module": "NodeNext",
    "sourceMap": true,
    "outDir": "./dist",

    "esModuleInterop": true,
    "moduleResolution": "nodenext"
  },
  "include": [
    "./src/**/*",
    "./assets/**/*"
  ],
  "exclude": [
    "node_modules"
  ]
}
```

**What's going on? Will I have to install all these modules separately?**It is not impossible that this is a TS2307 problem.stackoverflow.comtsc throws `TS2307: Cannot find module` for a local filetypescriptasked byDaniel Perez Alvarezon02:40PM - 31 May 16 UTCIn any case, it seems to me that you are definitely stumbling on some TS-specific issue. If you have a recent example that worked well, the quickest thing to do is to copy it…
