Running webpack executable watcher on Windows causes errors #1218

I created a new Phoenix project without brunch, mix phoenix.new yzerman --no-brunch and added webpack through npm, then added it to the watchers list,

watchers: [{ Path.expand("node_modules/webpack/bin/webpack.js"), ["--watch", "--colors", "--progress"] }]

Also added a webpack.config.js and a simple app.js file to see that it works.

But I get this error,

I then tried this,

watchers: [{ "node #{Path.expand("node_modules/webpack/bin/webpack.js")}", ["--watch", "--colors", "--progress"] }]

Which kind of works but still not,

Running the same command manually works perfectly,

What to do to get Phoenix to run this correctly?

Try

watchers: [node: ["node_modules/webpack/bin/webpack", "--watch", "--colors", "--progress"]]

If that doesn't work, this is unfortunately out of our hands as node on windows has seen some odd permissions issues that I don't think we can address.

Thanks a lot Chris! It does work with a slight correction, the extension .js is needed after webpack.
