@babel/traverse "Couldn't find a Program"

[npavlovichero]

Hello. Could someone help me shed some light as to what this error is exactly?

[nicolo-ribaudo]

Where are you getting this error from? Are you using @babel/traverse directly? It usually means that you are trying to traverse a subset of the AST, but the main traverse needs a full AST (starting from a node with type: "Program") to perform scope analysis.

what was it?

How to fix that?

[JLHwung]

This is a downstream bug: Intellicode/eslint-plugin-react-native#314. Before fix is landed, you can disable the react-native/no-raw-text rule.

Hi @JLHwung . Please, find bellow my .eslintrc:

module.exports = {
  root: true,
  extends: ['@react-native-community', 'plugin:react-native/all'],
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint', 'react', 'react-native'],
  "parserOptions": {
    "ecmaFeatures": {
      "jsx": true
    }
  },
  overrides: [
    {
      files: ['*.ts', '*.tsx'],
      rules: {
        '@typescript-eslint/no-shadow': ['error'],
        'no-shadow': 'off',
        'no-undef': 'off',
      },
    },
  ],
};

I have no react-native/no-raw-text rule

[JLHwung]

extends: ['plugin:react-native/all'],

I think that preset includes all react-native/* rules.

Hijacking this thread, since it's the first to come up in search results.

I have a monorepo setup with a React Native (Expo) app and I got the error while trying to run the app locally after upgrading Expo SDK.
For me, it's been caused by multiple equivalent version ranges in a lockfile pointing to two different versions of @babel/* packages (7.18.x and 7.19.x).
Deduplication fixed it. In my case, with Yarn, that's done by running yarn dedupe @babel/*.

I am not sure whether this is related or not but I got this in a CRA5 app and after some long time digging... I solved this with

Changing package.json

 "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

to

 "browserslist": {
  "production": [
    "chrome >= 67",
    "edge >= 79",
    "firefox >= 68",
    "opera >= 54",
    "safari >= 14"
  ],
  "development": [
    "last 1 chrome version",
    "last 1 firefox version",
    "last 1 safari version"
  ]
}

Hey I started facing this issue when updating to the latest version of RN (0.71), it doesn't seem to be related to eslint in my case.

You can find the complete info on my StackOverflow question

[JLHwung]

Did you try removing the npm/yarn lock files and install again?

[ospfranco]

yep, I nuked everything. Also tried deduping babel. No success.

[XantreDev]

fixed this issue for me

  "resolutions": {
    "@babel/traverse": "7.21.3",
    "@babel/core": "^7.21.3"
  }

[Jacksonishere]

Hi, couple months late here but did you end up figuring out a solution?

[ospfranco]

No, I tried the resolutions but it didn't work. I also left this months ago, maybe it is worth trying again with the latest versions.

Seemingly out of nowhere.
