Is there any workaround? How can I install Socket.io on windows 7 32 bit?

Answer 1

I'll share what worked for me on windows when trying to run npm install and got the "npm ERR! Error: EPERM, mkdir"...

I have to manually give permission to write to the folder...

In your case, you would need to go to

C:\Program Files\nodejs\node_modules\

Usin your windows explorer, right click, choose 'Properties' and go to 'Security' tab

You will see many users... just give privileges to the user you need and try running npm install again again...

Answer 2

Looks like you need to run it with admin privileges, try running the CMD with Administrator (Run as Administrator) and then npm install socket.io

Answer 3

Instead of vanilla command prompt, I used windows powershell (on win7) and above error was gone.
