Error installing i2c

When I type "npm install i2c" I get the following error:

What is wrong here?

Are you doing it on the Raspberry Pi? Only the Raspberry Pi will have the headers for I2C that this module is looking for...

[hyprstack]

No, I was just following the tutorial and it started with "npm install i2c".
So do I need to get the hardware? Help me out here, this is new to me. Thanks

Yes, to use i2c you need hardware that supports it. We are bringing Raspberry Pis, so you don't need to buy your own.
