Rule can be associated with only a single resource source, including the provided resource, test, include, or exclude

Hi there! I've encountered a persistent error with my Vue.js app that I can't seem to resolve. Even after reinstalling everything and clearing the cache, the issue remains. Any assistance would be greatly appreciated.

Error: Rule can only have one resource source (provided resource and test + include + exclude) in

  "exclude": [
    null
  ],

Answer №1

Removing webpack and downgrading to an earlier version did the trick!

npm uninstall webpack
npm install webpack@^4.0.0 --save-dev

Answer №2

Today, I came across the same error and resolved it by reverting the changes in my package-lock.json file.

After that, I ran a npm prune to get rid of unnecessary packages and updated with npm update to ensure everything was current.

Answer №3

After reverting back to "webpack": "^4.45.0", everything started working smoothly. I simply replaced the line with "webpack": "^4.45.0" in my package.json file and then executed the command npm update.

Answer №4

Encountered an issue in my package.json where "webpack" was set to 'latest', causing conflicts. Resolved by reverting back to webpack version 4.44.0, which successfully fixed the problem.

Answer №5

Seems like the issue is likely connected to the most recent Node (version 15) and npm (version 7).

Although my situation was a bit different, I faced the same challenge within my Dockerfile. I had to switch from node:alpine to node:lts-alpine

While everything worked fine locally with Node LTS version 14.15.0 and npm 6.14.8, the Dockerfile was set up with the latest versions.

Answer №6

These are the optimal versions I managed to reach in the package.json file without encountering the specified issue. You can seamlessly incorporate Vue 2 or 3 along with other libraries without any complications.

Suggested required versions post npm audit fix

Replace 'node-sass' with 'sass'

"dependencies": {
    "core-js": "^3.21.0"
},
"devDependencies": {
    "sass": "^1.60.0",
    "sass-loader": "^10.2.1",
    "webpack": "^5.77.0"
},

Minimum requirement with deprecation alerts

"dependencies": {
    "core-js": "^3.21.0"
},
"devDependencies": {
    "node-sass": "^6.0.1",
    "sass-loader": "^10.2.1",
    "webpack": "^4.46.0"
},

Subsequently, execute npm update

Answer №7

We encountered an issue when attempting to downgrade webpack, as css-loader required webpack 5.

Not specifying the version caused css-loader to automatically update to version 5, incompatible with webpack 3/4.

The fix was to manually set css-loader to version 3.6.0:

{
  ...
  "dependencies": {
    "core-js": "3.15.2",
    "vue": "^3.2.20",
    "vue-router": "^4.0.11",
    "vuex": "^4.0.2",
    "vuex-persist": "^3.1.3"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.14",
    "@vue/cli-plugin-router": "~4.5.14",
    "@vue/cli-plugin-vuex": "~4.5.14",
    "@vue/cli-service": "~4.5.14",
    "@vue/compiler-sfc": "^3.0.0",
    "sass": "^1.26.5",
    "sass-loader": "^8.0.2",
    "vue-loader": "^15.9.7",
    "vue-template-compiler": "^2.6.14"
  },
  "peerDependencies": {
    "css-loader": "3.6.0"
  }
}

The crucial step is updating the peerDependencies section. Delete package-lock.json and node_modules, then reinstall dependencies with npm i.

Answer №8

After downgrading the initial issue, I encountered another problem where I had to downgrade sass-loader as well. I received a TypeError stating that this.getOptions is not a function.

Answer №9

For any future researchers looking into similar issues:

Consideration should be given to avoiding downgrading WebPack versions if a ^5 version is necessary. Pay close attention to the error logs! It appears that '[email protected]' may be the culprit in this particular case. Attempt to update all libraries where this error is encountered, or discontinue use of outdated ones if updating is not feasible!

Answer №10

After adding the vue-loader, the issue was successfully resolved.

Answer №11

When I needed to install dependencies using npm, my process was as follows:

  1. Remove package-lock.json
  2. Delete node_modules
  3. Execute yarn install
  4. Launch yarn serve, and there you have it!
