ReferenceError: process is not defined

After including import { createBrowserHistory } from "svelte-routing"; I get:

warning.js:19 Uncaught ReferenceError: process is not defined

I am having a similar issue, tried upgrading the rollup, but it didn’t work. I am getting this issue for prepareRoutes from @curi/router

I found a solution by adding pacakge rollup-plugin-replace check it out if it helps npm install --save-dev rollup-plugin-replace

update your rollup.config file with ..... plugins: [ replace({ 'process.env.NODE_ENV': JSON.stringify( 'production' ) }) ] ....

In 2022, I was facing this issue yesterday, but it was happening because there was some errors in my imported ts files
