    • javascript

    • npm
    • babel-loader

    Please read this post. It describes what a peer dependency is.

    https://stackoverflow./a/34645112/2379376

    What that means is that you have webpack not installed at all or you have a different version (webpack 1.x) installed. But this plugin needs webpack in version 2 or 3 to function properly.

    What you can do is

    npm install webpack -g

    So npm will install the newest version of webpack on your system. But now other peer warnings could occur when other loaders need an older version of webpack.

    When using Webpack 4:

    I've faced the same error but I actually had the webpack 4 installed. In order to solve this I used the instruction on babel-loader documentation and installed the following extra libraries: babel-loader, @babel/core and @babel/preset-env.

    Command to install all the required libraries:

    npm install -D babel-loader @babel/core @babel/preset-env webpack

    package.json devDependencies before the installation:

      "devDependencies": {
    "chai": "^4.1.2",
    "enzyme": "^3.2.0",
    "enzyme-adapter-react-16": "^1.1.0",
    "expect": "^22.0.3",
    "jest-junit": "^3.3.0",
    "jest-junit-reporter": "^1.1.0",
    "node-sass": "^4.9.2",
    "prop-types": "^15.6.0",
    "react-test-renderer": "^16.2.0",
    "redux-mock-store": "^1.4.0",
    "sass-loader": "^6.0.6",
    "webpack": "^4.25.1",
    "webpack-cli": "^3.1.2",
    "webpack-dev-server": "^3.1.10"
  }

    After the installation:

    "devDependencies": {
  "@babel/core": "^7.1.6",
  "@babel/preset-env": "^7.1.6",
  "babel-loader": "^8.0.4",
  "chai": "^4.1.2",
  "enzyme": "^3.2.0",
  "enzyme-adapter-react-16": "^1.1.0",
  "expect": "^22.0.3",
  "jest-junit": "^3.3.0",
  "jest-junit-reporter": "^1.1.0",
  "node-sass": "^4.9.2",
  "prop-types": "^15.6.0",
  "react-test-renderer": "^16.2.0",
  "redux-mock-store": "^1.4.0",
  "sass-loader": "^6.0.6",
  "webpack": "^4.25.1",
  "webpack-cli": "^3.1.2",
  "webpack-dev-server": "^3.1.10"
}

    Hope it helps

    Install webpack globally in node environment as well as in development(as dev dependency). As main function of webpack is to bundle JavaScript files for usage in a browser.As each time you made changes to index.js (entry point of npm) at development time then you have to run webpack to make changes in bundle.js file also, so we need to install in both the environment(ie. node environment and development environment) Run below mand to solve the issue:

    npm install -g [email protected]
npm install --save-dev [email protected]

    Here I am using 3.10.0 for webpack. You can use 4 as well. I think this will help.
