React 脚本未在开发环境中运行 -Openshift答案

【问题描述】：

我正在将我的 React、Node 应用程序部署到 openshift 容器平台上。
我在后端同时运行命令。后端运行完美，没有任何问题。前端导致问题。

我正在同时运行这些命令，这些命令位于 package.json 后端文件夹中

"start": "node index.js",
"backend": "nodemon index.js",
"frontend": " npm run start --prefix ../frontend",
"frontendBuilt": "npm run built --prefix ../frontend",
"dev": "concurrently \"npm run backend\" \"npm run frontendBuilt\" ",

我试过以下都没有工作

"frontend": " npm  start --prefix /frontend",
"frontendBuilt": "npm  built --prefix /frontend",

"frontend": " npm start --prefix ../frontend",
"frontendBuilt": "npm built --prefix ../frontend",

以下是日志文本

如果我在 openshift 容器后端文件夹中运行 npm run dev 可以完美运行，没有任何问题

谁能告诉我哪里出错了？

【问题讨论】：

react-scripts start 命令是一个 dev 服务器，你不应该在生产环境中运行它。构建前端并让后端为其提供服务（就像我在这里所做的那样：github.com/textbook/starter-kit）或将静态资产部署到单独的（例如 Nginx）容器（可能需要更复杂的网络和配置）。
@jonrsharpe 请帮帮我，我是新手，我不知道应该使用“build”：“react-scripts build”，可以吗？该命令在后端同时运行，“要么让后端服务它” - 我理解正确吗？
这将创建您需要以某种方式提供服务的文件，是的。
@jonrsharpe“以某种方式服务”实际上我不想要某种方式，但这是我正在遵循的好/最好的方式（因为我不知道）还是有很多我不知道的好意识到实现

谢谢，@jonrsharpe 我正在为后端和部署的生产构建提供响应。码头工人的微小变化创造了奇迹。我对你的评论投了 +1 票
