javascript - AWS Elastic Beanstalk - 如何使用 npm 和 webpack 构建捆绑 JS

Question

我在 elasticbeanstalk 上部署了一个 Node js 应用程序。安装并符号链接(symbolic link) Node 、npm 和 webpack。但是在运行 npm run build-prod 时，它本身会调用脚本 webpack --config/var/app/current/webpack.prod.config.js。退出状态为 -2 时出现以下错误。如果我也直接运行 webpack 命令，也会发生同样的情况。我正在寻找解决方案。

容器配置文件:

container_commands:
  01_node_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"

  02_npm_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"

  03_npm_install_global_packages:
    command: "npm install webpack webpack-cli -g"

  04_webpack_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/webpack /bin/webpack"

  #05_webpack_run_build_prod:
    #command: "webpack --config /var/app/current/webpack.prod.config.js --progress --colors"

  06_npm_run_build_prod:
    command: "npm run build-prod"

package.json 中的脚本

"scripts": {
    "build": "webpack --config webpack.local.config.js --progress --colors",
    "build-local": "webpack --config webpack.prod.config.js --progress --colors",
    "build-prod": "webpack --config /var/app/current/webpack.prod.config.js",
    "server": "node app.js",
    "dev-server": "node dev-app.js"
  }

当我取消注释直接运行 webpack 命令的 05 时，它以错误结尾 Error: "/var/app/current/site-web/static/assets/app/index.js"is not in the源 map 。

构建脚本在本地成功，但在生产中的所有方式都被阻止。 无法弄清楚如何在 AWS beanstalk 环境中运行 webpack 命令来构建 JS。构建JS文件不是最理想的方式吗？

我对弹性 beantalk 还很陌生，我自己也有类似的问题，但我注意到您的符号链接(symbolic link) Node 、npm 等任务采用 container_commands 的形式。

According to the official docs , "它们在设置应用程序和 Web 服务器并提取应用程序版本文件之后运行，但在部署应用程序版本之前运行。"

也许尝试使用 commands: 而不是 container_commands:。查看我分享的链接。

也许这些命令在应用程序和 Web 服务器已经设置之后才运行，这就是为什么它可能不适合您的原因？

再说一次，我对 Elastic Beanstalk 还是新手，但也许这会有所帮助。
