Can't deploy webpack to gh-pages (react app)

问题

First time using webpack as well as deploying using gh-pages. I cloned a webpack project from a udemy course. Instructor doesn't get into how to actually use webpack. It's telling me that [etc.]/build doesn't exist. When I create a build folder, I get the same error.

package.json:

  "scripts": {
    "start": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js",
    "build": "webpack -p --config ./webpack.production.config.js",
    "test": "mocha --compilers js:babel-core/register --require ./test/test_helper.js --recursive ./test",
    "test:watch": "npm run test -- --watch",
    "predeploy": "npm run build",
    "deploy": "gh-pages -d build"
  },

webpack.production.config.js:

module.exports = {
  entry: ["./src/index.js"],
  output: {
    path: __dirname,
    publicPath: "/WeatherReact/",
    filename: "bundle.js"
  },
  module: {
    loaders: [
      {
        exclude: /node_modules/,
        loader: "babel",
        query: {
          presets: ["react", "es2015", "stage-1"]
        }
      }
    ]
  },
  resolve: {
    extensions: ["", ".js", ".jsx"]
  },
  devServer: {
    historyApiFallback: true,
    contentBase: "./",
    watchOptions: {
      aggregateTimeout: 300,
      poll: 1000
    }
  }
};

When I run yarn run deploy:

> webpack -p --config ./webpack.production.config.js

回答1:

You are receiving an error because build/ does not exist. Using the -d (or --dir) flag sets the basePath for the gh-pages tool.

You can change the script within package.json to "deploy": "gh-pages -d WeatherReact" which should deploy that folder and its contents.
