Solved Error npm run serve

[amimafe]

Hi,

I am trying to compile the DWC source code but when I launch the command "npm run serve" I get the following error.
What is the reason? Can someone help me?

Thank you very much.

@amimafe What branch are you trying to build? Try to run npm install before npm run serve.

Hi,

i've the same problem on Ubuntu 22.04 running node v21.0.0.

I cloned the repo from git (master) and installed it with npm install then executed npm run serve. The server compiles the files, and eventually displays the same error OP encountered.

In addtion a more extensive error is given, when I try to access the server, see screenshot

Looking at line 91335 in sass.dart.js shows, that navigator.userAgent seems to be undefined.

Sadly I'm pretty new to Node/Vue so I'm not really sure, what to do next.
Any suggestions? Thanks for the great work btw.

@amimafe @Nitroxid I could build the master branch immediately after cloning it without any additional changes. But I am still on Node 20, perhaps that makes a difference:

> npm -v
10.2.1
> node -v
v20.8.1

Also note that v3.4 and older require NODE_OPTIONS="--openssl-legacy-provider" to be set (as mentioned in the README) due to an incompatibility with Webpack 4. This option will be obsolete in v3.5.

@chrishamm Thanks for the help. I got it working with Node 20.8.1.

First I reinstalled it, by deleting node_modules and running npm install again. And after setting NODE_OPTIONS, npm run serve worked.

@chrishamm Thanks for your help. I was finally able to compile using an older version of Node.js. Version 18.18
I want to modify some DWC parameters to suit our machine.
I hope this can help other users with the same problem.
