NodeJs gives me this error on startup

  • 772

I'm new to Nodejs and I downloaded this code and I can't start it, I've already been working with other projects and they work fine (install the express and the cli, in addition to the node-telegram-bot-api as it says on gitHub) what could I be missing? the code is in the repository: https://github.com/yagop/node-telegram-bot-api

  1. The command:

    npm start

    looks in package.json for a script named "start" to execute the associated action. In this case, package.json doesn't contain a definition of "start" and that's why it gives you this error.

    It seems that the project you want to use is a library to be used from another program, and cannot be run by itself.

  2. As they say, you have several ways, those mentioned above and another one. I'm going to make a little guide to install the software, check the versions and run a script.

    INSTALLING NODE AND NPM

    Note that for a script that uses npm libraries to work you have to have:

    CHECK NODE AND NPM VERSIONS

    Once installed, we can check the version we have:

    From node:

    node -v

    From npm:

    npm -v

    For example, I have:

    RUN NODEJS SCRIPT

    There are 3 ways to run a node script via terminal.

    1. Run via npm start telling it which file:

    npm start index.js

    2.package.json Define the field in the file script:

    "scripts": {
  "start": "node index.js"
}

    And run with:

    npm start

    3. Run the script via the node command:

    node fichero.js

    Specifically, in the case of the yagop API it would be:

    node index.js

    in addition to npm start you must put the name of the .js file you want to start, eg: npm start app.js
