Issues during installation

[thojanssens]

The docs say:

Install dependencies with mix deps.get
Create and migrate your database with mix ecto.setup
Install Node.js dependencies with npm install --prefix assets
Start Phoenix endpoint with mix phx.server

When executing npm install --prefix assets (btw should tell that need to cd assets), it complains that package.json is missing a name and a version.

Then, after fixing the package.json file, when executing mix phx.server, it says:

Could not start node watcher because script "c:/data/projects/elixir/phoenix_live_view_example/assets/node_modules/webpack/bin/webpack.js" does not exist.

So I run npm install and then it works. Thus it seems that npm install --prefix assets is not enough.

npm: 6.14.2
node: v12.16.1

since your path starts with c:/ I guess you are on windows. there has been an issue with npm install --prefix assets on windows see Github Issue Comment

so maybe replace npm install --prefix assets with cd assets & npm install in the README for now so all users have a smooth process?

I also had the same problem in Windows and yes, I needed to go to the assets folder and run npm install from there to make it work.
