npm start does not work on vps



  • I checked the haxe official examples. While npm install and npm start worked fine locally. But when I tried to put them on my hosting's Vps it gave me this error:

    [root@server colyseus-official-examples]# npm start

    Hi @vishwasgagrani!

    By the error message, it seems that devDependencies listed under package.json were not installed during npm install:

    sh: ts-node-dev: command not found
    

    If you use npm install --only=dev the development dependencies should be installed as well.

    Let me know if that works for you!



  • Tried using -only=dev , but does not seems to solve the problem. Same error again. It is asking for peer dependencies though.

    npm install --only=dev
    npm WARN @colyseus/social@0.10.9 requires a peer of express-jwt@^5.3.1 but none is installed. You must install peer dependencies yourself.
    npm WARN colyseus-examples@1.0.1 No repository field.

  • Anyway I looked into package.json and saw this list:

    "@types/cors": "^2.8.6",
    "@types/express": "^4.17.1",
    "copyfiles": "^2.4.1",
    "rimraf": "^2.7.1",
    "ts-node": "^8.1.0",
    "ts-node-dev": "^1.0.0-pre.63",
    "typescript": "^3.4.5"

    And after installing ts-node-dev using:
    npm i ts-node-dev --save-dev

    I see the server running at 2567
    Listening on ws://localhost:2567

    Got it working for now. Thanks.
