Ruby-on-rails 捆绑安装不适用于 capistrano

bundle install doesn't work from capistrano

提问by freemanoid

I want to deploy my simple rails 4.0application via capistrano 3.0.

我想rails 4.0通过capistrano 3.0.

I use bundler 1.3.5so I add capistrano-bundlergem to integrate bundler with capistrano.

我使用bundler 1.3.5所以我添加了capistrano-bundlergem 以将 bundler 与 capistrano 集成。

I have pretty simple configuration (almost default):

我有非常简单的配置（几乎默认）：

set :bundle_gemfile, -> { release_path.join('Gemfile') }
set :bundle_dir, -> { shared_path.join('bundle') }
set :bundle_flags, ''
set :bundle_without, %w{test development}.join(' ')
set :bundle_binstubs, -> { shared_path.join('bin') }
set :bundle_roles, :all

When I run the cap staging deploy --traceit fails:

当我运行cap staging deploy --trace它失败：

But if I copy this command and run though ssh all works fine (all gems installed successfully) How I can fix/debug it?

但是如果我复制这个命令并运行 ssh 一切正常（所有 gems 安装成功）我如何修复/调试它？

Just ran into the same issue. What worked for me was this:

刚刚遇到了同样的问题。对我有用的是：

1) Installing the capistrano-rvmgem and adding

1）安装capistrano-rvmgem并添加

require 'capistrano/rvm'

to the Capfile.

到Capfile.

2) Adding my deployment user to the rvmgroup on the server:

2）将我的部署用户添加到rvm服务器上的组：

# usermod deploy -a -G rvm

3) Creating two directories in my deployment user's home folder: .rvmand .rvm/bin

3）在我的部署用户的主文件夹中创建两个目录：.rvm和.rvm/bin

4) Adding this line to my deploy.rbfile:

4）将此行添加到我的deploy.rb文件中：

set :default_env, { rvm_bin_path: '~/.rvm/bin' }

Phew! That took a few hours.

呼！那花了几个小时。

The error sounds like it can't find bundlein your PATH. It's possible that when you SSH in manually, it's running something in your ~/.profileor ~/.bash_profilethat adds it to your path.

该错误听起来像是bundle在您的PATH. 有可能当您手动 SSH 进入时，它正在您的路径中运行某些内容~/.profile或~/.bash_profile将其添加到您的路径中。

Find the path to bundleby logging in and running which bundle. Then, try to find how that path is added to your PATHenvironment variable. If there's something in your ~/.bash_profile, try moving it to~/.bashrc` instead.

bundle通过登录并运行找到路径which bundle。然后，尝试找出该路径是如何添加到您的PATH环境变量中的。如果你的~/.bash_profile, try moving it to~/.bashrc` 中有东西。

You can also try Command Mappingto specify an exact path.

您还可以尝试使用命令映射来指定确切的路径。

In my case, I changed config/deploy.rb's set :log_level, :infoto set :log_level, :debug, which showed me "Can not find GEMFILE." This suggested that bundlewas running with the wrong working directory, so I changed

就我而言，我将 config/deploy.rb 更改set :log_level, :info为set :log_level, :debug，这显示“找不到 GEMFILE”。这表明bundle使用错误的工作目录运行，所以我改变了

before "deploy:assets:precompile", "deploy:bundle_install"
desc "Bundle install for RVMs sake"
task :bundle_install do
  on roles(:app) do
    execute "/u0/jrepenni/.rvm/bin/rvm 2.1.0@akiary do /u0/jrepenni/.rvm/gems/ruby-2.1.0@global/bin/bundle install"
  end
end

to

到

before "deploy:assets:precompile", "deploy:bundle_install"
desc "Bundle install for RVMs sake"
task :bundle_install do
  on roles(:app) do
    execute "cd #{release_path} && /u0/jrepenni/.rvm/bin/rvm 2.1.0@akiary do /u0/jrepenni/.rvm/gems/ruby-2.1.0@global/bin/bundle install"
  end
end

(note the added "cd")

（注意添加的“cd”）

I had:

我有：

set :bundle_flags, '--system --quiet'

Changed to:

变成：

set :bundle_flags, '--deployment --quiet'

This resolved a problem.

这解决了一个问题。

This works in capistrano 3:

这适用于 capistrano 3：

  task :bundle_list do
    on roles(:app) do
      within release_path do
        with rails_env: fetch(:rails_env) do
          execute :bundle, "list"
        end
      end
    end
  end

Use this for rake task :

将此用于 rake 任务：

execute :rake, 'some_rake_task'

in your config/deploy/production.rb file put

在您的 config/deploy/production.rb 文件中放入

set :rvm_ruby_version, '2.0.0-p247'

gem install bundler 

is what I needed to run on my deploy user in order for Capistrano's:

是我需要在我的部署用户上运行以便 Capistrano 的：

/usr/local/rvm/bin/rvm 2.4.0 do bundle install --path /var/www/hivebench-api/shared/bundle --without development test --deployment --quiet

to pass!

通过！

回答by blat

To debug it try to remove the --quietflag:

要调试它，请尝试删除该--quiet标志：

set :bundle_flags, '--deployment'

set :bundle_flags, '--deployment'

Are you using rbenv, rvm or something similar? It might be possible that when bundleis running the Ruby version is not set yet. By removing the --quiteflag you might get some debugging information.

你在使用 rbenv、rvm 或类似的东西吗？可能bundle还没有设置运行 Ruby 版本的时间。通过删除--quite标志，您可能会获得一些调试信息。
