eaccess : erlang.open_port spawn executable -> C:/Program Files/nodejs/npm.cmd

[baskint]

First of all, thanks so much making this boiler plate code available. I have followed the instructions and got the app to work on my Ubuntu box and pushed it to heroku.

However, having issues on Windows system (I know that is a bit afterthought), I am thinking somewhere the pipe specific to windows, we are building the directories. I suspect either the spaces in the path or lacck of back slashes in the path is causing this error. Any thoughts where I could fix this?

Thank you for any ideas.

Thanks for the report and sorry for late reply. It's caused by weird npm permission issue on windows. You can simply replace line in config/dev.exs from this watchers: [npm: ["run", "start", cd: Path.expand("../assets", __DIR__)]]

to this watchers: [node: ["node_modules/webpack-dev-server/bin/webpack-dev-server.js", "--colors", "--stdin", cd: Path.expand("../assets", __DIR__)]]

I will fix this in the next commit. Please close issue if now it works. Let me know if it didn't work out for you.

It worked out great. I made the changes on Windows machine and pushed, and pulled it on Ubuntu. Confirm that it works on Ubuntu was well. It sure is weird. I was thinking it was something with the paths, but it was not. Thank you for the fix. Cheers! 🎊
