@coding102 Do you have any process running on port 8080? Like nginx or something?

[coding102]

Rails = localhost:3000
pgAdmin4 = Port 5433

On powershell if typed netstat -an and found this port listening

TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING

I killed it and it's now compiling thanks

I am having similar problem. In my case this is the error
yarn run v0.27.5
$ "~\investxd-frontEnd\node_modules.bin\webpack-dev-server" "--progress" "--color" "--config" "~/learningPython/investxd-frontEnd/config/webpack/development.js"
The filename, directory name, or volume label syntax is incorrect.

@EmmaAkin I'm having the exact same problem!! can't believe no one posted a fix so far.

Have you managed to solve it?

[pensebien]

@Spazer9 did not fix it. I resolve not to go the rails/vuejs route rather I went with rails api and vuejs front end. Everything is fine, only that I have to write more ajax code to handle api calls.

@EmmaAkin @Spazer9 This might be a problem with yarn on Windows - one solution proposed is #584 which might be merged soon. Essentially webpack works if you bypass yarn run webpack and go straight to node_modules/.bin/webpack.
