使用 rvm1-capistrano3 安装 Ruby

Question

当我跑步时

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 . )

无法确定使用哪个 Ruby； .应包含 .rvmrc 或 .versions.conf 或 .ruby-version 或 .rbfu-version 或 .rbenv-version，或 Gemfile 中的适当行。
上限中止！

编辑

在我的应用程序的根目录添加.ruby-version 后，我得到的内容

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 }

我还在输出中遇到另外两个错误：

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

Answer 1

问题

如果你去远程服务器并执行这个：

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

你会得到同样的错误，但如果你改为执行这个

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

成功。 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 中指定要安装的所需 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

Answer 2

应用程序不知道要使用哪个版本的 ruby​​。

您需要做的就是在应用程序的根目录中添加一个名为.ruby-version 的文件，并将其内容设为

1.9.3

或者你正在使用的任何版本的 ruby​​。

您可能还需要一个.ruby-gemset 文件。在这种情况下，它的内容应该是

some_gemset_name

您可以随意调用 gemset。它在您的应用程序中是本地的。
