无法弄清楚为什么docker compose up没有运行我的React JS App [英] Not able to figure out why docker compose up is not running my React JS App
问题描述
我想借助docker-compose和docker文件在docker容器中运行react应用。它显示缺少package.json文件，但是我确实在尝试与docker容器映射的本地目录中有该文件。
I want to run a react app in a docker container with the help of a docker-compose and docker file. It is showing package.json file is missing but I do have that file in my local directory which I am trying to map with the docker container.
我已经通过运行 docker-compose build 命令成功构建了映像。但是，当我尝试运行 docker-compose up 命令时，它显示在错误下方
I have successfully built the image by running docker-compose build command. But while I am trying to run docker-compose up command it is showing below error
PS E:\Project\MyProfile\my-profile> docker-compose up
Starting myprofile_web_1 ... done

我的机器是Windows 10，请告知我是否需要更多信息。
My machine is Windows 10 and let me know if you all need any further information.
我的Docker文件：
My Docker File:
FROM node:alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD [ "npm","run","start" ]
Docker Compose File ：
Docker Compose File:
version: '3'
services:
web:
build:
context: .
dockerfile: Dockerfile.dev
ports:
- 3000:3000
volumes:
- /app/node_modules
- .:/app
更新1：
正如彼得建议的那样，我在Docker容器中查看 app目录，在那里可以看到package.json文件。
As Peter suggested I look into 'app' directory in the Docker container I can see package.json file there.

解决方案：
我能够通过将Project移到C：/ User / {User_Name}文件夹来解决此问题。可以在此处找到相同的解释（找不到Docker卷和package.json ）
I was able to resolve this issue by moving my Project to C:/User/{User_Name} folder. Explaination for the same can be found here (Docker volumes and package.json not found)
如果您不想像我一样移动文件夹，也可以将其签出（如何在docker计算机中安装本地卷）
If you do not want to move folders just like me you can do that as well checkout this (How to mount local volumes in docker machine)
