将Node.js应用程序推送到Heroku时出错

Question

我正在尝试在heroku上部署一个nodejs站点。该站点在heroku local上运行良好，但是当我尝试将其推送到heroku remote时，出现错误提示。你能帮我吗？

remote: /tmp/build_75e4a69a5c93328a55b43b1f2ca7ee85/.heroku/node/lib/node_modules/npm/bin/npm-cli.js:79
remote:       var notifier = require('update-notifier')({pkg})
remote:                                                     ^
remote: SyntaxError: Unexpected token }
remote:     at Module._compile (module.js:439:25)
remote:     at Object.Module._extensions..js (module.js:474:10)
remote:     at Module.load (module.js:356:32)
remote:     at Function.Module._load (module.js:312:12)
remote:     at Function.Module.runMain (module.js:497:10)

如果其他人落在这里，matching the node versions为我工作。在package.json文件中，确保当前节点版本与engines部分匹配：

{
  "name": "myapp",
  "description": "a really cool app",
  "version": "1.0.0",
  "engines": {
    "node": "12.x"
  }
}
