webrtc error with mime.lookup

问题

I tried webrtc demo on my PC. but in demo step-04. When I use npm install and node index.js,it shows "TypeError: mime.lookup is not a function".

even after I installed mime by typing "npm install mime"

How can I fix this and make the demo work?

回答1:

use mime-type instead of mime. So, Install mime-types first:
    npm install mime-types
then make change in your code:
    var mime=require('mime-types');

I'm having the same issue with step 4. You can changing the node-static version from 0.7.7 to 0.7.10 in package.json and rerunning npm install

  "dependencies": {
    "node-static": "0.7.10",
    "socket.io": "1.2.0" }

回答3:

if you have a folder "node modules" in your root directory,delete that and type npm cache clear and then type npm install.this should work fine

回答4:

I have the same issue but then try to use mime ~1.2.7 and i think this will work fine. just change your version of mime in package.json file and install it.

回答5:

change mime.lookup(type) to mime.getType(type)

回答6:

As @HRISHABH RAJ mentioned you want to reference mime-type instead of mime however you should check your node_modules folder first to see if the package is already installed.
