我已经创建了一个在我的本地服务器上正常运行的Web应用程序（Vue JS前端，Sails JS后端）。但是，当我尝试运行它时，我会遇到错误;主要是依赖错误。我已经在Heroku上部署了它。我必须在我的app文件夹的根目录中创建一个package.json文件。
以下是应用树的外观：
root folder
|---frontend
|---package.json file
|---backend
|---package.json file
|---package.json file
我用vue cli webpack创建了前端应用程序。
"name": "zigy-demo-store",
"version": "1.0.0",
"description": "A demo online store with Admin functions.",
"main": "backend/app.js",
"scripts": {
"dev": "cd backend && npm i && npm run dev & cd frontend && npm i && npm run build",
"start": "cd backend && npm i && npm run dev & cd frontend && npm i && npm start"
},
"dependencies": {
"sails": ""
},
"repository": {
"type": "git",
},
"engines": {
"node": "^10.15",
"npm": "6.7.0"
}
}
这是一些错误

看起来我的路径有问题。在错误日志中，我看到链式命令是：
cd backend && npm i && npm run dev & cd frontend && npm i && npm start
根据你的树结构，frontend目录中没有backend目录，这使得cd frontend失败。在进入../之前，尝试在那里添加一个frontend上升一级：
cd backend && npm i && npm run dev & cd ../frontend && npm i && npm start
好的，我只是将前端和后端部署为Heroku上的单独应用程序。我按照本教程在Heroku上进行Vue.js + webpack部署：https://codeburst.io/quick-n-clean-way-to-deploy-vue-webpack-apps-on-heroku-b522d3904bc8
而不是推动前端文件夹，我只推动位于前端文件夹中的dist /文件夹。我遵循了除git init部分之外的文章中的步骤。我进入了dist文件夹并在那里做了我的git init。
