Docker 构建失败 - 创建 React App + Tailwind /bin/sh: craco: 未找到

Question

几天来我一直被这个问题困扰。我正在尝试 dockerize django REST API + react (create-react-app) 应用程序。由于我使用的是 tailwindcss，因此 React 应用程序使用 craco 进行构建。我按照本指南将 Tailwind 与 React 应用程序集成，当我运行 yarn 在本地启动时它正在工作。

指南：https://tailwindcss.com/docs/guides/create-react-app

问题是当我运行使用 docker-compose 时它抛出 /bin/sh: craco: not found 错误。我什至尝试在前端 Dockerfile 中的 运行 yarn 之后添加 运行 yarn add @craco/craco -g但它显示相同的错误。

运行宁docker-compose up --build时出错：

问题是您将主机目录和卷映射到映像中包含节点模块和应用程序文件的目录。

尝试在 docker-compose 文件中删除此部分。这样你就不会覆盖图像中的内容，并且 craco 将可用。

volumes:
  - ./frontend:/app/frontend
  - node-modules:/app/frontend/node_modules

当您使用 docker-compose 构建和运行您的映像时需要注意的一件事是，卷仅在运行阶段映射，而不是在构建期间。
