如何在 Symfony4 中修复 "manifest file does not exist."

Question

我正在使用 Webpack 在 Symfony 4.2 中开发一个项目。我正在使用 BitBucket 对代码进行版本控制，并使用 heroku 进行部署。该应用程序在我本地机器上的开发环境中运行良好。但是我在 Heroku 的生产模式下有一个错误。服务器找不到文件 manifest.json，我的资产文件生成 404 错误。

这是我的 assets.yaml 配置文件的内容：

framework:
    assets:
        json_manifest_path: '%kernel.project_dir%/public/build/manifest.json'

以下是我遇到的错误：

我测试了网上找到的几种解决方案，但 none 有效。 :(

Answer 1

这也发生在我身上，在 git 克隆了我一直在使用的存储库（不同的计算机）之后。 Symfony4 项目。我安装了运行 yarn install 和 composer install，然后设置了 db，然后出现了这个清单文件错误。经过一些研究后，我修复它的方法是：运行 encore to build the assets :-)

Answer 2

我终于解决了这个问题。问题是 gitignore 文件。我的文件没有配置好。我将这些行添加到 gitignore 文件中：

###> symfony/webpack-encore-bundle ###
/node_modules/
!/public/build/
!/public/build/*
npm-debug.log
yarn-error.log

现在可以使用了
