I'm writing a node module to be open sourced and there's a dependency on some Ruby code (see Can I include a Ruby Gem in a Node.js project? for details). I made a Ruby project that requires some gems and all of that works well. In my node_module, I want to interface it via exec to the Ruby code.
我正在编写一个开放源代码的节点模块，并且依赖于一些Ruby代码(请参见我是否可以在节点中包含一个Ruby Gem)。js项目吗?详情)。我做了一个需要一些宝石的Ruby项目，所有这些都很好。在node_module中，我希望通过exec与Ruby代码进行接口。
But now there's Ruby dependencies as well. So can I somehow specify the Ruby version, and the gemset required to run my node package?
但是现在还有Ruby依赖项。那么我是否可以指定Ruby版本，以及运行节点包所需的gemset ?
Ambiguous question perhaps. I can clarify if anything is unclear.
模棱两可的问题。如果有什么不清楚的话，我可以澄清。

I don't think you can/should specify the Ruby version to use when executing your code. That should be up the library consumer so choose. Since you want to execute your code with exec, the library consumer will have the added responsbility of making ruby accessible to the node process. How that happens is not up to you as the library developer.
我认为您不应该在执行代码时指定要使用的Ruby版本。这应该由库使用者决定。由于您希望使用exec执行代码，因此库使用者将具有使节点进程能够访问ruby的附加响应性。如何实现这一点并不取决于您作为库开发人员。
As for dependencies/gemsets, just use bundler.
对于依赖项/gemsets，只需使用bundler。

Maybe you could do something like this - without more information it's hard to say.
也许你可以做这样的事情——如果没有更多的信息，这很难说。
-
On the ruby side, build your gem to do whatever it needs to do and then add a rake task to it. How you build this rake task is obviously up to the demands of the project and how it will be used, but it will provide a way for you to interface from the outside.
在ruby端，构建您的gem来做它需要做的任何事情，然后向它添加一个rake任务。如何构建rake任务显然取决于项目的需求以及如何使用它，但它将为您提供一种从外部接口的方式。

In the 'middle' build a bash script that includes RVM - this way you can require a specific gemset/do specifc things before running the rake task. Another benefit is that if you want to change the gemset or other implementation details, you just change the bash script.
在“中间”构建一个包含RVM的bash脚本——通过这种方式，您可以在运行rake任务之前需要一个特定的gemset/do specifc。另一个好处是，如果希望更改gemset或其他实现细节，只需更改bash脚本。

On the node side, call the bash script. More info on that in this answer.
在节点端，调用bash脚本。更多关于这个答案的信息。
