I am trying to run npm with the command npm run start but I'm getting an error which seems to be happening when the webpack dev server tries to open:

> election@1.0.0 start C:UsersAristophaneselection_reactelection_react-0.0.1

> webpack-dev-server --open

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I have run npm install -g webpack-dev-server as this has been the solution for similar errors, but the issue persists. Can anyone help? Thanks.

try running a local version of webpack-dev-server, it uses: "Note: While you can install and run webpack-dev-server globally, we recommend installing it locally. webpack-dev-server will always use a local installation over a global one."
