尝试将我的应用程序（Node，React，Socketio）部署到Heroku会给我“ sh：1：react-scripts：权限被拒绝”

Question

So I am trying to make my first react app. I have it working just fine locally. The problem is that I cannot upload my project to Heroku.

This is my app setup: my file arrangement . I built this starting with a create-react-app, wrapped that entire thing in a "client" folder, and created a normal node server arrangement outside . I haven't touched my react app's package.json" except to add a socketio dependency, other than that it is exactly what create-react-app spits out.

I get this error on console when attempting to upload: "sh: 1: react-scripts: Permission denied"

I have gone through https://devcenter.heroku.com/articles/nodejs-support , but to no avail.

This is my "outside" package.json scripts and dependencies

"scripts": {
    "client": "npm start --prefix client",
    "server": "node server.js",
    "start": "concurrently \"npm run server\" \"npm run client\"",
    "heroku-postbuild": "cd client && npm run build"
},
"dependencies": {
    "concurrently": "^4.0.1",
    "express": "^4.16.4"
    "socket.io": "^2.1.1"
}

UPDATE:

I've not gotten my application to work yet HOWEVER I finally found something interesting.

This: https://github.com/mars/heroku-cra-node

Looks like a barebones application I can essentially my stuff to, and have it work on Heroku. I've not added my code yet, I'll report back.

UPDATE:

Yep, seems to get past this permission BS. Now I just have to deal with getting socket.io client to connect... -_-

Change your script to this:

  "scripts": {
    "start": "node index.js",
    "server": "nodemon index.js",
    "client": "npm run start --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "heroku-postbuild": "NPM_PRODUCTION=false npm install --prefix client && npm run build --prefix client",
  },

npm run dev will start your server and client in development mode...

You can also install nodemon to make your life easier...
