gitlab上的CI / CD无法使用babel-loader进行编译

问题描述 投票:2回答:2

我有一个webpack的反应应用程序。开发服务器按预期工作。当我在本地运行webpack --mode production时,它会按预期构建并创建一个js包。当我将它推送到gitlab时,它无法构建它并出现错误:

ERROR in ./src/index.js 20:16
Module parse failed: Unexpected token (20:16)
You may need an appropriate loader to handle this file type.
| firebase.initializeApp(config);
| 
> ReactDOM.render(<App />, document.getElementById('app'));
| 

这些是我的devDependencies:

"devDependencies": {
  "@babel/core": "^7.2.2",
  "@babel/plugin-transform-flow-strip-types": "^7.2.3",
  "@babel/plugin-proposal-class-properties": "^7.2.3",
  "@babel/plugin-proposal-decorators": "^7.2.3",
  "@babel/plugin-proposal-object-rest-spread": "^7.2.0",
  "@babel/preset-env": "^7.2.3",
  "@babel/preset-react": "^7.0.0",
  "babel-eslint": "8.2.6",
  "babel-loader": "^8.0.4",
  "copy-webpack-plugin": "4.6.0",
  "css-loader": "0.28.11",
  "eslint": "4.19.1",
  "eslint-loader": "2.1.1",
  "eslint-plugin-react": "7.11.1",
  "html-webpack-plugin": "3.2.0",
  "style-loader": "0.21.0",
  "webpack": "^4.28.2",
  "webpack-cli": "^3.1.2",
  "webpack-dev-server": "^3.1.14"
}

这是我的webpack配置:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = {
  entry: './src/index.js',
  output: {
    path: path.join(__dirname, 'build'),
    filename: 'index.bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: [/node_modules/, /build/],
        use: ['babel-loader', 'eslint-loader']
      },
      {
        test: /\.css$/,
        use: ['style-loader', 'css-loader']
      }
    ]
  },
  devServer: {
    historyApiFallback: true
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './public/index.html',
      filename: 'index.html'
    }),
    new CopyWebpackPlugin([
      { from: path.join(__dirname, 'public/'), to: path.join(__dirname, 'build') }
    ])
  ]
};

这是以前工作,但我更新了库已经过时了。更新后,gitlab ci失败。

这是构建配置:

image: node:latest

cache:
    paths:
        - node_modules/

stages:
    - setup
    - build

setup:
    stage: setup
    script:
        - echo "Setup started"
        - yarn install
    artifacts:
        paths:
            - node_modules/

build:
    stage: build
    script: 
        - yarn build
    artifacts:
        paths:
            - build/

编辑我已经发现index.js所以也许条目不好或什么的,但后来我在组件内部得到了一堆错误,它无法解析jsx标签。我怀疑babel-loader没有在gitlab-ci上工作。

编辑29.3.2019我没有找到解决方案。截至你可以在github上有免费的私人回购,将项目迁移到github和setup circleci。 Circleci完美地为我工作。

"react": "^16.4.1",
"react-dom": "^16.4.1"

对你的devDependencies它应该工作。

由于你没有在react中提供react-dompackage.json模块,因此错误即将发生。

让我知道它是否适合你,如果不是我们会期待这个问题

更新:

image: node:latest

cache:
    paths:
        - node_modules/

stages:
    - setup
    - build

setup:
    stage: setup
    script:
        - echo "Setup started"
        - yarn install
    artifacts:
        paths:
            - node_modules/

build:
    stage: build
    script: 
        - yarn install react
        - yarn install react-dom
        - yarn build
    artifacts:
        paths:
            - build/

直接将安装命令添加到脚本应解决此问题。不知何故,你的webpack没有找到reactreact-dom的安装目录,所以传递安装命令将在构建时明确提供模块。

我刚刚与Gitlab CI有同样的问题,发现排除是问题所在:

exclude: [/node_modules/, /build/]

尝试使用以下内容替换它:

exclude: '/node_modules/',
include: [
    path.join(__dirname, 'src')
]

它现在适用于本地和Gitlab CI。之前,它只在本地工作。

还有另一个问题指向了正确的方向:Webpack build fails with Gitlab-CI
