Ruby和Rails“；“未找到路径”；在Docker上使用RVM安装时

我正在处理docker文件，以便在其上创建自定义工作区。当我创建工作区时，一切似乎都安装正确，但当工作区打开并输入

ruby-v

时，我得到：

bash:ruby:command未找到

轨道也一样：

user@de98ec223612:/projects$ rails -v
bash: rails: command not found

如果我键入rvm列表，我将得到

user@de98ec223612:/projects$ rvm info

ruby-2.4.0:

在我看来，一切都安装正确了

如果我键入

/home/user/.rvm/rubies/ruby-2.4.0/bin/ruby-v

，它将显示正确的ruby版本

/home/user/.rvm/rubies/ruby-2.4.0/bin

在路径中，为什么不进行搜索

这里是我的docker文件的相关部分，如果有帮助的话

如何让这些命令在不使用

/home/user/.rvm/rubies/ruby-2.4.0/bin的情况下运行？
如果您的团队可以接受，那么从Eclipse Che为RoR提供的基本dockerfile开始可能更容易：

这会让你了解基本知识，社区也会不断更新。然后，您可以使用所需的任何其他工具、库和deps来扩展它。
我也遇到了同样的问题，最终我通过上传一个以

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

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

带有源代码的行由我添加。RVM在安装时添加了导出。我的bashrc文件的其余部分是由Debian安装的内容。我刚加了几行

我的ruby.sh文件包含

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

对我来说，就是这样。当我使用/bin/bash（非shell）或通过/bin/bash-l-c“这里有命令”登录时，我的命令rvm和ruby都会响应。还有，我的红宝石之家和宝石之路。。。都满了

我当前的ruby docker安装可以在以下位置找到：

忘了提。我在/opt中安装rvm。
