ruby-on-rails - 使用 rvm1-capistrano3 安装 Ruby

Question

当我运行时

cap production rvm1:install:ruby

我在控制台输出的末尾收到此错误:

Command: cd ~/apps/foo/releases/20140121133714 && ( PATH=/opt/ruby/bin:$PATH /usr/bin/env /tmp/foo/rvm-auto.sh rvm install . )

Could not determine which Ruby to use; . should contain .rvmrc or .versions.conf or .ruby-version or .rbfu-version or .rbenv-version, or an appropriate line in Gemfile.
cap aborted!

编辑

在我的应用程序的根目录添加一个 .ruby-version 之后，我得到了内容

我正在使用 rvm1-capistrano gem 运行 Capistrano 3.1.1。它是开箱即用的实现；没什么特别的。

group :development do
  gem 'capistrano', '~> 3.1.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
  gem 'rvm1-capistrano3', require: false
# gem 'capistrano-rvm'
end

# capfile
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rails'
require 'capistrano/bundler'
require 'rvm1/capistrano3'
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

我还在输出中得到另外两个错误:

Running /usr/bin/env [ -L ~/apps/foo/releases/20140121135720/public/assets ] on foo.com
Command: [ -L ~/apps/foo/releases/20140121135720/public/assets ]

问题

如果你去远程服务器执行这个:

cd ~/apps/foo/releases/20140121160854 && /usr/bin/env /tmp/foo/rvm-auto.sh rvm install .

你会得到同样的错误，但如果你改为执行它

cd ~/apps/foo/releases/20140121160854 && /usr/bin/env /tmp/foo/rvm-auto.sh rvm install ruby-2.0.0-p247

成功。当 rvm-auto.sh 执行 rvm install . 命令时出现问题。不确定是否是 rvm 问题，但在我看来是这样......

解决方法

如果您在 config/deploy.rb 中指定要安装的 ruby​​ 版本:

set :rvm1_ruby_version, "ruby-2.0.0-p247"

在执行任何 rvm1 任务之前。一切都应该没问题
