【问题描述】：
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。我已经完成了以下任务。
- 在 EC2 中创建了 Ubuntu 机器并安装了 Docker 引擎。
- 将整个
React代码复制到其中一个文件夹中，添加DockerFile和Docker-composeyml 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，现在只需部署一个React应用程序。 - 在执行
docker-compose up之后，容器将被创建并立即退出。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'导入反应； ^^^^^
SyntaxError：意外的标识符 在 Module._compile (internal/modules/cjs/loader.js:723:23) 在 Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10) 在 Module.load (internal/modules/cjs/loader.js:653:32) 在 tryModuleLoad (internal/modules/cjs/loader.js:593:12) 在 Function.Module._load (internal/modules/cjs/loader.js:585:3) 在 Function.Module.runMain (internal/modules/cjs/loader.js:831:12) 启动时（内部/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。
这里是package.json 文件，以防你能帮助找出问题。

这里是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。
