Error: Unable to locate the type definition file for the '@babel' package

I am currently working on a new project and here is the content of my package.json file.

{
  "name": "dapp-boilerplate",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "eslint . --ext .js,.jsx,.ts,.tsx",
    "format": "prettier --write . --ignore-path .gitignore ./next-env.d.ts",
    "typechain": "typechain --target ethers-v5 --out-dir ./contracts/types './contracts/*.json'"
  },
  "dependencies": {
    "@types/": "metamask/providers",
    "@types/eslint": "^8.4.8",
    "next": "^12.3.1",
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },

    "prettier": "2.7.1",
    "typechain": "^8.1.0",
    "typescript": "^4.1.3"
  }
}

Recently, I encountered an issue while running yarn build. Initially, I suspected it was due to eslint, but that wasn't the case. Does anyone have a solution for this problem?

yarn run v1.22.19
$ next build
info  - Linting and checking validity of types .Failed to compile.

Type error: Cannot find type definition file for '@babel'.
  The file is in the program because:
    Entry point for implicit type library '@babel'

error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Moreover, when attempting to deploy to netlify, I encountered an unexpected error. After running yarn build, I came across the aforementioned error message.

Answer №1

To ensure you have the necessary type definition file for babel, follow these installation steps:

npm install --save-dev @types/babel

Answer №2

To update your jsconfig.json file, make sure to include the following code snippet:

{
  "compilerOptions": {
      "types": ["babel__generator"],
      "typeRoots": ["node_modules/@types", "path/to/your/custom/types"],
      //Additional options can be added here
   },
   //Other configurations should be unchanged...
}

If this solution does not resolve the issue, consider installing the following packages:

npm i --save-dev @types/babel

npm i --save-dev @types/babel__core

npm i --save-dev @types/babel-generator
