ESLint version 8.0.0 encountered an error while attempting to fetch the '@typescript-eslint' plugin

Hey there, I'm in need of some assistance. I encountered an error while trying to build a project.

Uh-oh! Something didn't go as planned! :(

ESLint: 8.0.0

TypeError: Failed to load plugin '@typescript-eslint' specified in 'src.eslintrc': Class extends value undefined is not a constructor or null Referenced from: src.eslintrc

package.json

    "devDependencies": {
        "@typescript-eslint/eslint-plugin": "^4.33.0",
        "@typescript-eslint/parser": "^4.33.0",
        "browserslist": "^4.17.3",
        "eslint": "^8.0.0",
        "eslint-config-prettier": "^8.3.0",
        "eslint-plugin-import": "^2.24.2",
        "eslint-plugin-prettier": "^4.0.0",

Answer №1

I followed these steps and everything worked perfectly for me

"@typescript-eslint/eslint-plugin": "^5.0.0",
"@typescript-eslint/parser": "^5.0.0",
"eslint": "^8.1.0",

Make sure to update the above mentioned three packages

After that, navigate to the root of your project and execute this command to update the packages

npm install

Following these instructions will ensure everything functions smoothly

Answer №2

Encountered an issue while attempting to utilize version 4.x.x of the @typescript-eslint packages:

  "devDependencies": {
    ...
    "@typescript-eslint/eslint-plugin": "^4.29.1",
    "@typescript-eslint/parser": "^4.29.1",
    ...
}

Solution involved upgrading these to version "^5.3.1"

Answer №3

It seems like there may be a compatibility issue with ESM in one of the packages. To resolve this, ensure that all your dependencies are ESM compatible or lock eslint to version 7.32.0 and update the plugins accordingly (I also suggest adding TypeScript to your dev dependencies):

  "devDependencies": {
    ...
    "@typescript-eslint/eslint-plugin": "^5.6.0",
    "@typescript-eslint/parser": "^5.6.0",
    "eslint": "^7.32.0",
    "typescript": "^4.4.3"
  }

To achieve this, you can execute the following command:

npm i --save-dev typescript @typescript-eslint/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1075637c797e643d607c6577797e50253e263e20">[email protected]</a> @typescript-eslint/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="26564754554354661308100816">[email protected]</a> <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="80e5f3ece9eef4c0b7aeb3b2aeb0">[email protected]</a>

The --save-dev flag is used to install these as development dependencies since they are only needed for building and development purposes.

Answer №5

After upgrading my node version from 12.12.0 to 16.0.0, the problem was finally resolved. It seems that the issue was related to using an outdated node version.

Answer №6

After updating my node.js to version 16, everything is running smoothly now.

Answer №8

Running into problems? It might be due to the mismatch between the node and react versions you have installed. To resolve this, make sure your node version is compatible with React by updating it accordingly.
