卡皮斯特拉诺·v3找不到一个班德勒。

I have a problem in deploying my App with Capistrano v3. When I run '$ cap production deploy' I see an error...

我在部署Capistrano v3时遇到了一个问题。当我运行“$ cap生产部署”时，我看到一个错误……

但是当我运行最后一个命令时…

…通过我的服务器上的ssh，我没有看到任何错误。

SOLVED

解决了

I've solved my problem by following steps:

我通过以下步骤解决了我的问题:

Add capistrano-rvm into Gemfile and do

将capistrand -rvm添加到Gemfile中并执行

...
group :development do
  ...
  gem 'capistrano', '~> 3.0.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
  gem 'capistrano-rvm'
end
...

Add this line into Capfile

将这一行添加到Capfile中

require 'capistrano/rvm'

Add these lines into the deploy.rb file.

将这些行添加到部署中。rb文件。

set :rvm_ruby_version, '1.9.3-p448'
set :default_env, { rvm_bin_path: '~/.rvm/bin' }
SSHKit.config.command_map[:rake] = "#{fetch(:default_env)[:rvm_bin_path]}/rvm ruby-#{fetch(:rvm_ruby_version)} do bundle exec rake"

3 个解决方案

#1

It seems that you had to add capistrano-rvm. It will take care about your ruby and bundler paths.

看来你得加上capistrand -rvm。它将关心您的ruby和bundler路径。

bundle install doesn't work from capistrano

bundle安装不能从capistrano工作。

#2

... via ssh on my server I don't see any errors.

…通过我的服务器上的ssh，我没有看到任何错误。

The problem you are seeing is probably due to missing rbenv, chruby, or rvm. This is a really common one and it's documented here how to resolve, verify and/or work around (whichever works for your case) here:

您看到的问题可能是由于缺少rbenv、chruby或rvm。这是一个非常常见的问题，这里有关于如何解决、验证和/或在这里工作的文档(无论您的情况如何):

http://www.capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/

#3

If you use system rvm (path = /usr/local/rvm/bin/rvm), set capistrano-bundler as below

如果您使用系统rvm (path = /usr/local/rvm/bin/rvm)，请将capistrand -bundler设置为如下所示

set :rvm_type, :system
set :rvm_ruby_version, 'ruby-<version>@<gemset>'
