Hi @ac_bolt_diy,
we need a bit more informations. E.g. System OS, how you installed it, NodeJS Version, etc.
Maybe take a look at my install Video on Youtube, if not done, to make sure you got all needed steps:
Windows 11
$ pnpm --version
10.5.2
$ node --version
v20.18.3
$ npm --version
10.8.1
I followed the same step from this video.
Thanks 
were there any errors while doing the pnpm install command?
no issues on pnpm install
on pnpm dev and open http://localhost:5173
just the console error above (about something related to PWA i guess ??)
dont know, cause working without problems for me.
just to be sure, you did not try to install with “npm install” before, recognized then that it should be “pnpm install” and did this quite after? cause this can lead to problems.
maybe just try to do a clean project again
git clone -b stable https://github.com/stackblitz-labs/bolt.diy.git
cd bolt.diy
pnpm install
pnpm run dev
nope , i only use pnpm
git clone -b stable https://github.com/stackblitz-labs/bolt.diy.git
cd bolt.diy
pnpm install
pnpm run dev
tried this , but same issue
Issue resolved by using a different port:
pnpm dev --port 5174
It didn’t work on default port 5173, even though I verified that the port wasn’t in use. The reason remains unclear.
If anyone encounters a similar issue, try using a different port. Let me know if you have insights on why this might happen!
Thanks
ok thats strange, cause normally it auto switch to the next available port. I often have multiple terminals open with different versions, which works fine.
but glad you got it working
