RVM报告未安装Gemfile红宝石 [英] RVM reports Gemfile ruby as not installed

问题描述

在我的Gemfile中，我已指定:

In my Gemfile, I have specified:

ruby '1.9.3', engine: 'jruby', engine_version: '1.7.9'

但是进入我的Rails项目目录会使rvm抛出此错误:

But entering my Rails project directory makes rvm throw up this error:

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /home/petey/rails/kotoba/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

ruby-1.9.3,engine:jruby,engine_version:1.7.9 is not installed.
To install do: 'rvm install ruby-1.9.3,engine:jruby,engine_version:1.7.9'

但是，我确实安装了jruby 1.7.9:

However, I do have jruby 1.7.9 installed:

$ rvm list

rvm rubies

   jruby-1.7.9 [ x86_64 ]
   ruby-1.9.3-p392 [ x86_64 ]
=* ruby-2.0.0-p247 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

$ rvm use jruby
Using /home/petey/.rvm/gems/jruby-1.7.9

$ ruby -v
jruby 1.7.9 (1.9.3p392) 2013-12-06 87b108a on OpenJDK 64-Bit Server VM 1.7.0_25-b30 [linux-amd64]

事实上，我什至可以用rvm use jruby选择它，并且rails可以正常工作.

In fact, I can even select it with rvm use jruby and rails works fine.

Gemfile中的ruby指令是否存在问题?

Is there a problem with the ruby directive in the Gemfile?

我遵循官方规范，该示例具有非常相似的示例.

I followed the official specification, which has a very similar example.

编辑:在提示符下运行rvm install ruby-1.9.3,engine:jruby,engine_version:1.7.9时，rvm继续安装ruby-1.9.3-p484.再次，它在输入项目目录时显示相同的错误消息:

On running rvm install ruby-1.9.3,engine:jruby,engine_version:1.7.9 at the prompt, rvm proceeds to install ruby-1.9.3-p484. And once again, it shows the same error message on entering the project directory:

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /home/petey/rails/kotoba/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

ruby-1.9.3,engine:jruby,engine_version:1.7.9 is not installed.
To install do: 'rvm install ruby-1.9.3,engine:jruby,engine_version:1.7.9'

推荐答案

根据此答案:

RVM对ruby指令的支持有限，您可以使用注释来覆盖RVM将使用的内容.

RVM has limited support of the ruby directive, you can use comment to overwrite what will be used by RVM.

通过添加:

By adding:

#ruby=jruby-1.7.9

在ruby指令下方的Gemfile中，rvm似乎能够选择正确的红宝石:

to the Gemfile just below the ruby directive, rvm seems to be able to pick the right ruby:

$ cd kotoba
RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /home/petey/rails/kotoba/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

$ ruby -v
jruby 1.7.9 (1.9.3p392) 2013-12-06 87b108a on OpenJDK 64-Bit Server VM 1.7.0_25-b30 [linux-amd64]
