Debugging Ruby on Rails error: ActionView::Template::Error (Webpacker can't find media/images/...

gistfile1.txt

Sometimes, this error occurs when I run a rails app on my local:

```
ActionView::Template::Error (Webpacker can't find media/images/...
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:
...
```

Try to precompile your assets:

`bundle exec rails assets:precompile`

In one of my projects, when I tried to precompile the assets, it issued the error:
```
Compiling...
Compilation failed:
.../nodejs/16.5.0/bin/node: --openssl-legacy-provider is not allowed in NODE_OPTIONS
```

The reason was that my system had an old nodejs version.
I updated nodejs to 20.8, and it fixed the issue.
