Rails webpacker不读取app / javascript / images文件夹

Using the default configuration of rails/webpacker I could not read a file through the <%= asset_pack_path 'images/calendar.png' %> helper in a view. Reading the docs it seems easy to do, but something goes wrong trying access the page:

使用rails / webpacker的默认配置，我无法通过视图中的<％= asset_pack_path'images / calendar.png'％>帮助程序读取文件。阅读文档似乎很容易，但尝试访问页面时出现问题：

Webpacker can't find application.css in /path/manifest.json. Possible causes:

Webpacker在/path/manifest.json中找不到application.css。可能的原因：

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. 除非使用webpack -w或webpack-dev-server，否则您希望将环境的webpacker.yml值设置为true。
3. Webpack has not yet re-run to reflect updates.
4. Webpack尚未重新运行以反映更新。
5. You have misconfigured Webpacker's config/webpacker.yml file.
6. 您配置错误的Webpacker的config / webpacker.yml文件。
7. Your Webpack configuration is not creating a manifest. Your manifest contains:
8. 您的Webpack配置未创建清单。您的清单包含：

Am I missing some configuration?

我错过了一些配置吗？

It seems a docs misundertand as the awnser:

这似乎是一个文档误解和作为awnser：

asset_pack_path only references assets used as pack (i.e. JS packs file) or assets used inside a pack like a font, image or styles referenced that's why it's not present inside manifest.json. asset_pack_path doesn't look inside any folder like rails view helpers for assets.

asset_pack_path仅引用用作包的资产（即JS包文件）或包内使用的资产，如引用的字体，图像或样式，这就是manifest.json中不存在的原因。 asset_pack_path不会查看任何文件夹，例如rails视图帮助程序的资产。

Perhaps use Rails image_path helper if you want to reference images that’s not used inside packs.

如果要引用包内未使用的图像，也许可以使用Rails image_path帮助程序。
