Question

我正在尝试使用this tutorial在一个centos容器中安装rbenv。当我在bash中运行这些命令时，我们可以使用它们，但是当使用docker build时，我会得到以下错误。

FROM centos:latest

RUN yum install -y sudo git vim git-core zlib zlib-devel gcc-c++ patch readline readline-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison curl sqlite-devel

RUN cd
RUN git clone git://github.com/sstephenson/rbenv.git .rbenv
RUN echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
RUN echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
RUN exec $SHELL

RUN git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
RUN echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
RUN exec $SHELL
RUN source ~/.bash_profile

RUN rbenv install -v 2.2.1
RUN rbenv global 2.2.1

RUN echo "gem: --no-document" > ~/.gemrc

RUN gem install bundler

输出

我做错了什么？

Answer 1

您的源命令处于RUN状态，因此在下一个命令中会忘记它

使用Dockerfile运行命令时出错
