我正在尝试将Webpacker集成到我正在开发的Rails 4应用程序中。我已经将gem添加到Gemfile中,并运行指令来设置所有要使用Webpacker和Vue.js的内容。资产在开发中可以正常编译,但是当我将其推送到CI管道时,我看到CircleCI返回以下错误:
ActionView::Template::Error: ActionView::Template::Error: Webpacker can't find application in /home/circleci/app/public/packs-test/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:
{
}
不确定要解决哪些错误。
我的config/webpacker.yml
文件仅使用默认设置,如下所示:

我需要更正清单文件吗?如果可以,怎么办?
谢谢!

确保您的圈子ci配置中包含NODE_ENV
和RAILS_ENV
。如果尚未运行安装命令bundle exec rails webpacker:install
,请同时运行它。

已通过在.circleci/config.yml
中添加以下内容来解决:
Docker映像:
image: circleci/ruby:<<ruby_version>>-node-browsers
(这是必要的,这样我们就可以预安装Node.js的Docker映像)
环境变量:
NODE_ENV: test
这是必要的,以便webpacker:compile
步骤在测试环境下运行。
然后执行以下步骤:
yarn_install:
steps:
- restore_cache:
keys:
- yarn-cache-v1-{{ checksum "yarn.lock" }}
- yarn-cache-v1-
- run: yarn install --cache-folder ~/.cache/yarn
- run: bundle exec rake webpacker:compile
- save_cache:
key: yarn-cache-v1-{{ checksum "yarn.lock" }}
paths:
- ~/.cache/yarn
这似乎已经成功了!

我最近遇到了这个问题,并尝试了接受的解决方案,但是它对我不起作用。在CircleCI上运行规格时,我遇到了与OP相同的错误。
我的解决方案是在现有的yarn install
步骤中包括rails webpacker:compile
和bundle
,如下所示:
- run: yarn install
- run: bin/rails webpacker:compile
然后我将public/packs-test
添加到缓存中的文件夹:
- save_cache:
key: v1-bundle-{{ checksum "Gemfile.lock" }}-{{ checksum "yarn.lock" }}
paths:
- vendor/bundle
- public/packs-test
如您所见,我将yarn.lock
文件的校验和添加到了缓存键中,以确保如果在包中进行了任何更改,都可以重新生成缓存。
