SyntaxError：在 Docker 容器上部署 React 应用程序时出现意外标识符

Question

我是 ReactJS 世界的新手，正在帮助一个团队将他们的 React 应用程序部署到 Docker 容器。 我完成了以下任务。

1. 在 EC2 中创建 Ubuntu 机器并安装 Docker 引擎。
2. 将整个React代码复制到其中一个文件夹中，添加DockerFile和Docker-compose yml 文件。 团队几乎没有其他应用程序可以一起部署，这就是我包含 docker-compose 文件的原因。 但是，现在只部署一个React应用程序。
3. 完成docker-compose up容器后，将立即创建并退出。 然后我检查了退出容器的日志（如下所示）。

/usr/src/app/src/index.js:1 从 'react' 导入 React； ^^^^^

SyntaxError: Unexpected identifier at Module._compile (internal/modules/cjs/loader.js:723:23) at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10) at Module。在 tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js: 585:3) 在 Function.Module.runMain (internal/modules/cjs/loader.js:831:12) 在启动 (internal/bootstrap/node.js:283:19) 在 bootstrapNodeJSCore (internal/bootstrap/node.js) :623:3)

我研究了这个错误，看起来这是因为编译、缺少 webpack 或 React 应用程序中的某些东西。 我不确定要在 React 中修复什么以及在哪里修复。

这是package.json文件，以防您可以帮助找出问题。

}

这是DockerFile的内容

FROM node:10
# FROM alpine:latest
WORKDIR /usr/src/app

# add node_modules/.bin:$path
ENV PATH /usr/src/app/node_modules/.bin:$PATH

# Install app dependencies
COPY package*.json ./

RUN npm install


# Bundle app source
COPY . .

#
EXPOSE 80
CMD npm start

而且， docker-compose文件如下所示。

version: "3"

services:
  web:
    build: ./pdf_web_frontend
    command: "node src/index.js"
    ports:
      - "800:80"

你觉得上面有什么问题吗？ TIA。

注意：我已经看到这个链接SyntaxError: Unexpected identifier importing React (Javascript)

Answer 1

经过大量研究，我可以部署这个反应应用程序。 以下是问题。

1. 问题在于dockerfile和dockerfile docker-compose文件。 我添加了具有不同内容的全新文件。

2. React 应用程序正在部署到一些悲惨的端口。 因此，我在package.json文件中明确添加了 PORT 8080。 这不是一个干净的解决方案，但这有效。

下面是新文件。
