Docker：docker-compose爲捆綁流星應用程序不工作..（npm錯誤）

Question

任何人都可以幫助我解決這個問題？我目前正試圖通過docker-compose來捆綁我的流星應用程序，並且不斷來回地收到npm錯誤。我終於到達Docker-compose.yml文件所調用的Dockerfile中的最後一個構建步驟，但是我收到了很多錯誤..所有文件，包括package.json，都清晰可見，因此在那裏是沒有理由的，除其他外，從安裝隱藏。

這裏是我的dockerfile和以下是錯誤：

你並不需要在Dockerfile安裝節點。使用節點泊塢窗圖像作爲基礎圖像。 https://hub.docker.com/r/_/node/

然後安裝您擁有的其他依賴項，例如python。使用WORKDIR泊塢窗指令，然後將您的文件複製到WORKDIR。

FROM node:wheezy 

RUN mkdir /home/app 

WORKDIR /home/app 

COPY app.tar.gz . 
RUN tar -zxf app.tar.gz && npm install && apt-get update && apt-get install -y python && cd bundle/programs/server && rm -rf /var/lib/apt/lists/* 

# Expose port 80, but remember to use PORT=80 
EXPOSE 80 

# Run the app 
CMD ["node", "main.js"]
