Opensea clone. yarn run wont work

Hey guys
I have just started the opensea clone and it seems yarn run isnt working. it says no license field in my package.json. I tried adding a license and will continue trying. Has anyone done this before?
Cheers :slight_smile:

@johnversus here is my post :slight_smile:

Did you run yarn install?
and make sure you are running the command in the correct project folder path

Hi John
yes I wasn’t in the right directory. My fault sorry.
I do have this pop up after I do yarn start and I’m in the Dapp. If I click the x in the top right it goes away and I can continue. Do you think this will be a issue down the track.
Cheers

running yarn format should solve it

Hi John
Yes yarn format has fixed that issue. Thank you.
I do have this popping up now. Can I get delete or comment out the section at line 90:34 in the parenthesis? I’m going to continue with the video as I dont think this will cause any issues later.

Hi John
I was able to figure this issue out. Thanks for your help. I’m having a issue with changing the buttons at the top of the page. Mine looks a little different to the video and I thought I found the place to change this but I couldn’t get them to actually change when I reloaded the page.

Hi John
I’ve fixed this issue now.
Cheers

Some reason I cant get the page to load now and everything else on my computer loads so I Don’t think it is the internet.

There must be some error. Check the browser console

Hi John
It just needed to be refreshed a few times. I have no issues now. Thank you for your help
Cheers :slight_smile:
