我想这是一个环境问题.
当我手动执行它(没有Dockerfile)时,它可以工作.
这是我的Dockerfile：
FROM ubuntu:14.04
RUN apt-get update
RUN apt-get upgrade --assume-yes
RUN apt-get install wget vim git --assume-yes
# install RVM
RUN apt-get install build-essential curl --assume-yes
RUN curl -L https://get.rvm.io | bash -s stable
RUN echo 'source /etc/profile.d/rvm.sh' >> ~/.bashrc
RUN /usr/local/rvm/bin/rvm-shell -c "rvm requirements"
# install Ruby
RUN /usr/local/rvm/bin/rvm-shell -c "rvm autolibs enable"
RUN /usr/local/rvm/bin/rvm-shell -c "rvm install 2.1.2"
# install Rails
RUN echo "gem: --no-rdoc --no-ri" >> ~/.gemrc
RUN gem install rails -v 4.1.5
# install nodeJS
RUN sudo apt-get install nodejs --assume-yes
EXPOSE 3000
比我建立：
sudo docker build -t="james/rails" .
我收到了这个错误：
Step 11 : RUN gem install rails -v 4.1.5
---> Running in 44efc6b7c254
/bin/sh: 1: gem: not found
2014/09/04 18:33:52 The command [/bin/sh -c gem install rails -v 4.1.5] returned a non-zero code: 127
最佳答案
尝试RUN / bin / bash -l -c“gem install rails -v 4.1.5”而不是你在那里的那条线.这有什么改变吗？
