Import module in nodejs-CodePudding

I am trying to import a node module in node 12.22.5

const Gpio = require('pigpio').Gpio;

But I get an error telling me that require is not defined

CodePudding user response：

It happens when you declare your package type as module in your package.json. If you do this, certain CommonJS variables can't be used, including require.

To fix this, remove "type": "module" from your package.json and make sure you don't have any files ending with .mjs.

For Raspberry Pi, you first need to install the module, then you can use it:

npm install pigpio
