Looks like you have installed socket.io in a different location to your current path. Either install globally like below:
npm install -g socket.io
Or reference the location you've installed to:
var io = require('../lib/socket.io');
Thanks ajtrichards!
Just to add to the answer - in case you simple use
sudo npm install socket.io
The installation path will be
/home/.../.npm/socket.io
If you use sudo npm install -g socket.io
The installation path will be
/usr/local/lib/node_modules/socket.io
In first case, I tried adding the socket.io path in global path variable but it did not work.
you might have installed but not added to the dependencies in package.json
Use below command to install socket.io module
npm install socket.io --save
Hope this will resolve your problem..
I had this problem with NodeJs, Typescript and Socket.io 4. the error was:
TS2792: Cannot find module 'socket.io'.
So my fix was to update the tsconfig.json adding a new property (moduleResolution).
tsconfig.json:
{
"compilerOptions": {
....
"moduleResolution": "node",
}
}
I had the same issue with version 0.12.0 on Windows. I tried npm install -g socket.io but that didn't change anything. Also tried npm cache clean also no change, but after npm update npm -g, things got well.
This almost happens than you try to get socket.io in you html files like :
index.html
where you have:
< script type="text/javascript" src="/socket.io/socket.io.js"></script>
It will not find socket.io because you did not started module in you application file wich contain the server like
server.js
You must include following lines after started your server in server.js :
var io = require('socket.io').listen(server);
Hope, will save time.
I fixed it by adding "moduleResolution": "node"
in tsconfig.json(which was inspired by
the discussion above) and then restart my VScode. Hope this will help others.
I think that you have executed the command npm install socket.io
in a different location and your files are in different directory..
So either run the command in the same directory which have your files or either mention the path where you have currently installed socket.io in your PATH variable.
I had the same problem in mac... you can install the module with sudo npm install socket.io-client
Please check all your js file wherever you mentioned or called socket.io where in in my case it was a spelling mistake sokcet.io that I corrected and start working.
