Error running npm run web:dev on windows

Hi

When I try running your project web part on windows 10 machine I get the following error:

23 error You can get information on how to open an issue for this project with:

23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls rfx-stack
23 error There is likely additional logging output above.

api part starts fine. What might be a problem

Many thanks.

so the problem was in webpack.config.babel in windows, match.script is not matching the npm script name, so I replaced the function with process.env.npm_lifecycle_event === “web:dev” and got passed the error, but then I got

C:\Users\rickm\Documents\Google Drive\Projects\NodeJS\rfx-stack\src\shared\app.js:34 var uri = [‘http://’, config.io.host, ‘:’, config.io.port].join(‘’); ^

TypeError: Cannot read property ‘io’ of undefined

and got tired of debugging 😃

EDIT: ookaayyy gave it another shot and there was indeed cross OS env shenanigans going on so I installed cross-env and change package.json to “web:dev”: “cross-env NODE_ENV=development node ./run/start.web.js”

and it worked (I’m on win 10), cheers
