Webpacker error from Vue.js Trello Clone Series
Rails
• Asked by Victor Bordo
Hey all, I have an error that I just can't get to the bottom of. While going through the awesome Vue.js Trello Clone tutorial I started seeing this:
(Webpacker can't find application.css in /trello-clone/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
unless you are using the `webpack -w` or the webpack-dev-server.
2. Webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your Webpack configuration is not creating a manifest.
Your manifest contains:
{
"application.js": "/packs/application-7842a75bb83838259e67.js",
"application.js.map": "/packs/application-7842a75bb83838259e67.js.map",
"hello_vue.js": "/packs/hello_vue-dbd5bbf8a9e291bb9804.js",
"hello_vue.js.map": "/packs/hello_vue-dbd5bbf8a9e291bb9804.js.map"
}

rails tmp:clear assets:clobber
I've downgraded the webpack-dev-server as per this issue https://github.com/rails/webpacker/issues/1303
I've also tried pulling down the final version of the clone from Github and running it in a Docker container and still actually get the same issue. I'm sure it's something small on the config side that I'm doing incorrectly. I'm working on a Mac running High Sierra (10.13.3). Any guidance is much appreciated, thanks!
You can get that error if you made a typo because it can't compile the file. Try checking your code for errors.
Couldn't spot any typos so I rolled back to the second commit (where I am in the tutorial) on master and now it's working which rules out a config err. I'm sure you're right and it was a little typo. Just needed some fresh eyes. Thanks for responding so fast Chris! GoRails is a fantastic resource and I'm already learning Rails rapidly thanks to you.
I get a similar error with my own Rails 5.2/VueJS application when deploying to heroku. The application runs fine without errors locally, so I don't think a typo in my JS code could be the reason. The manifest.json file is created fine, but other than that, my public/packs folder remains empty. Any hints as to in which file I made have a typo to cause this error?
Ok, my mistake was, that I used webpack version 4, which is not compatible with the latest release of the webpacker gem. Downgrading webpack to version 3 solved the problem – now assets are compiled.
