如何为生产环境设置 webpacker on rails？

Question

我正要在服务器上设置/部署我的项目，所以我尝试先在本地机器上使用生产环境运行它，以确保它正常运行。 但是，我对使用的资产有疑问。

我使用 rails 5.2 版，webpacker 5.4 版和 nginx。

目前在我的 Windows 电脑上使用 docker 和 docker-compose 对其进行测试。

我清除了public/assets和public/packs然后执行RAILS_ENV=production bundle exec rake assets:precompile

它能够生成和编译资产。

但是如果在浏览器上查看，布局被破坏并且浏览器控制台上有很多错误：

这是我的config/webpack/production.js ：

process.env.NODE_ENV = process.env.NODE_ENV || 'production'

const environment = require('./environment')

module.exports = environment.toWebpackConfig()

我已经坚持了一段时间了。

谢谢你。

Answer 1

如果您可以分享您的 docker-compose.yaml 和 Nginx 配置，是否有可能？ 我猜这是由错误的 Nignx 配置引起的。

Answer 2

在进行precompile之前，我必须先运行yarn install ，然后它才能正常工作。 对不起，我认为那是我错过的。
