在Docker上使用RVM安装Ruby和Rails“路径未找到”

问题描述：

我正在处理docker文件以在Codenvy上创建自定义工作区。当我创建工作区一切似乎正确安装，但工作区时开放，我进入ruby -v我得到：在Docker上使用RVM安装Ruby和Rails“路径未找到”

bash: ruby: command not found

同为轨道：

[email protected]:/projects$ rails -v 
bash: rails: command not found

如果键入RVM名单，我得到

[email protected]:/projects$ rvm info 

ruby-2.4.0:

    IRBRC:  "/home/user/.rvm/rubies/ruby-2.4.0/.irbrc" 
    RUBYOPT:  "" 
    gemset:  ""

这看起来像我的东西正确安装。

如果我键入/home/user/.rvm/rubies/ruby-2.4.0/bin/ruby -v它显示正确的ruby版本。 /home/user/.rvm/rubies/ruby-2.4.0/bin在PATH中为什么不被搜索？

这是我的码头文件的相关部分，如果有帮助。

# Install bundler 
RUN /bin/bash -l -c 'gem install bundler' 

# Install Rails 
RUN /bin/bash -l -c 'gem install rails' 

RUN echo $PATH 

EXPOSE 3000 
WORKDIR /projects  

CMD /bin/bash -l -c 'source ~/.rvm/scripts/rvm' && sudo service postgresql start && tail -f /dev/null

获得这些命令，而无需使用/home/user/.rvm/rubies/ruby-2.4.0/bin起到任何帮助将是非常赞赏。

如果接受你的团队很可能更容易开始与基地dockerfile了Eclipse车提供的回报率：https://github.com/eclipse/che-dockerfiles/blob/master/recipes/ruby_rails/Dockerfile

这应该让你的基础知识，它是保持由社区跟上时代的。然后，您可以使用任何其他工具，库，你需要的代码来扩展它。

我有同样的问题，最后我

source /opt/rvm/scripts/rvm 
source /etc/profile.d/ruby.sh 

export PATH=$PATH:/opt/rvm/bin

与源线固定它通过上传结束了/root/.bashrc中的文件，由我添加。导出是由RVM在安装时添加的。我的bashrc文件的其余部分是由Debian安装的内容。我刚刚添加了这些行。

我ruby.sh文件包含

#!/bin/sh 
export RUBY_HOME=/opt/rvm/rubies/default

对我来说，做的伎俩。当我使用/ bin/bash（非shell）或通过/ bin/bash -l -c“命令进入此处”登录时，我的命令rvm和ruby都响应。另外，我的RUBY_HOME和GEM_PATH，...都被填满了。

我现在的红宝石泊坞窗安装可以在这里找到： https://github.com/vindevoy/dockerhub-debian-ruby（来源） https://hub.docker.com/r/vindevoy/debian-ruby/（图）

忘了提。我在/ opt中安装rvm。 – user3256848
