windows – 构建docker镜像时无法npm安装依赖项

我在Windows上使用boot2docker,我的Dockerfile是：

FROM ubuntu:15.04

RUN apt-get -y update 
RUN apt-get -y install nodejs 
RUN apt-get -y install npm 

COPY /server /src
COPY /server/package.json /tmp/package.json

RUN cd /tmp && npm install

(etc)

错误消息是：

sh:1 node: not found
npm WARN: This failure might be due to the use of legacy binary "node"
npm WARN: For further explanations,please read
/usr/share/doc/nodejs/README.Debian

npm ERR! sails@0.11.0 preinstall: 'node ./lib/preinstall_npmcheck.js'

虽然它说它可能是Sails的问题,但我在我的机器上安装它没有问题.当我运行图像时(显然)我无法安装它,当我尝试运行ubuntu：15.04图像并在那里安装npm和Sails时,它告诉我npm是一个未找到的命令.

我还是Docker的新手(对Windows–我甚至找不到npm-debug.log)所以任何类型的建议都有很大帮助.

谢谢！
