建立一个反应项目

Question

我正在使用webpack和babel从头开始建立一个react项目。在运行时会引发错误。请帮我。

我附上错误的屏幕截图。我的通天塔没有正确安装。我要去哪里错了？

Answer 1

let data = Data::from_template(app.get_library().get(1), "hi");
app.get_consumer_mut().consume(data);

您必须将软件包安装为dev-dependency。

Answer 2

尝试一下：

webpack.config.js

module: {
    rules: [
      {
        test: /\.js$/,
        use: ['babel-loader']
      }
    ]
  },

.babelrc

{
  "presets": ["env", "react", "stage-2"]
}

package.json

  "devDependencies": {
    "babel-cli": "^6.26.0",
    "babel-core": "^6.26.3",
    "babel-loader": "^7.1.4",
    "babel-preset-env": "^1.7.0",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-2": "^6.24.1",
    "react-hot-loader": "^4.3.3",
    "webpack": "^4.15.0",
    "webpack-cli": "^3.0.8",
    "webpack-dev-server": "^3.1.4"
    ....
