Javascript：权限被拒绝

Question

I've followed this tutorial for Rabbitmq in Javascript. These are the codes: https://github.com/rabbitmq/rabbitmq-tutorials/blob/master/javascript-nodejs/src/send.js

https://github.com/rabbitmq/rabbitmq-tutorials/blob/master/javascript-nodejs/src/receive.js

But, when I try to run them with ./send.js and/or ./recv.js it gives me "Permission denied" error.

I look for some solutions but I don't understand, or I find something about IE (that it's not my case) - plus I don't think the problem is the browser (?) If it's so... why? :/

Answer 1

Well, i think you are wrong with few things... you are trying to run it without node or an interpreter.

• If a file it's not a module like file, you should use node ./file.js
• If a file it's a module you must to use something like this var myModule = require('./myModule.js); and use its functions.
• If a file it's a browser script you should use like this <script src="/file.js"></script> and use its functions.

I don't know that software and how it works, but that are the essentials usages of common javascript files.

Answer 2

You're trying to run Javascript from the command line. This answer details how to do it with Node, with instructions from Command Line Javascript . Here's a quick rundown:

• Download and install Node
• Create the file hello.js containing just one line:
  console.log('Hello, world');
• Running your program is easy; invoke node on the file containing your program:
  node hello.js
