AWS Elastic Beanstalk - 如何使用npm和webpack构建bundle JS

Question

我在elasticbeanstalk部署了一个节点js app.已安装且符号链接的节点,npm和webpack.但是在运行时npm run build-prod会调用脚本webpack --config /var/app/current/webpack.prod.config.js.退出状态-2出现以下错误.如果我直接运行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05直接运行webpack命令时,它以错误结束 Error: "/var/app/current/site-web/static/assets/app/index.js" is not in the SourceMap.

构建脚本在本地成功,但在生产的所有方式上都被阻止.无法弄清楚如何运行webpack命令在AWS beanstalk环境中构建JS.是不是构建JS文件的理想方式？

node:4.4.6 npm:2.15.5 webpack:latest

我对 Elastic beanstalk 仍然很陌生，并且自己也遇到类似的问题，但我注意到您的符号链接节点、npm 等任务采用container_commands.

根据官方文档，“它们在应用程序和 Web 服务器设置完毕并提取应用程序版本文件之后、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:. 请参阅我分享的链接。

也许这些命令直到应用程序和 Web 服务器已经设置好之后才会运行，这就是为什么它可能不适合您？

再说一次，我对弹性豆茎还是新手，但这也许会有帮助。
