我试图dockerise我的节点应用程序。我目前的应用程序是一个使用postgresql的nodejs express服务器。 ExpressJS使用node-sass-middleware来处理sass资产。当我在我的OSX机器上本地运行node和postgresql时,一切正常。当我尝试用docker-compose
运行应用程序,我得到一个“缺少绑定错误”发布到节点sass和Docker
这里是我的Dockerfile:
FROM node:7.2.1
RUN apt-get update -qq && apt-get install -y build-essential
RUN apt-get install -y libpq-dev postgresql-client
ENV APP_HOME /my_app
RUN mkdir $APP_HOME
WORKDIR $APP_HOME
ADD package.json .
RUN npm install
RUN npm rebuild node-sass
ADD . .
CMD [ "npm", "start" ]
EXPOSE 3000
这里是我的docker-compose.yml
文件:
version: '2'
services:
db:
image: postgres:9.6.1
ports:
- '5432:5432'
web:
build: . # use the Dockerfile next to this file
volumes:
- .:/my_app
ports:
- "3000:3000"
depends_on:
- db
当我运行泊坞窗 - 组成我仍然得到以下错误:

我虽然通过将RUN npm rebuild node-sass
添加到Dockerfile中,它将为Docker容器中的操作系统构建正确的绑定...但它似乎不起作用。
有什么想法?
您尝试安装的是哪个版本的node-sass-middleware/node-sass。节点7的支持只是最近添加了 – nschonni
@nschonni我使用的节点sass中间件版本0.9.8 – jubeless
