由于ubuntu的未满足的依赖关系，无法安装节点6的npm
这是错误消息：

The command '/bin/sh -c apt-get install -y npm' returned a non-zero code: 100 它来自运行这个dockerfile：
FROM ubuntu:16.04 RUN apt-get update -y RUN apt-get install -y curl # To install node 6 RUN curl -sL https://deb.nodesource.com/setup_6.x | bash - RUN apt-get install -y nodejs RUN apt-get install -y npm RUN apt-get install -y git
我通过docker build -t mysystem .启动了docker build -t mysystem .
我想原始apt-get数据库中的npm与nodejs不兼容。 我怎样才能纠正这一点？ 我想考虑nvm作为我的最后的手段
npm包含节点，所以你应该罚款只有：
apt-get install -y nodejs
