Capistrano無法安裝

Question

每當我嘗試運行cap production deploy它都會在以下命令中失敗

[ebbf9fde] Command: cd /var/www/apps/my_app/releases/20150803171251 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/my_app/shared/bundle --without development test --deployment --quiet
DEBUG [ebbf9fde]    /usr/local/rvm/scripts/set: line 19: exec: bundle: not found

我添加了一個用戶'deploy'來執行此部署， rvm list的輸出是

$ rvm list

rvm rubies

=* ruby-2.2.2 [ x86_64 ]

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

進一步運行gem列表的輸出是

$ gem list

*** LOCAL GEMS ***

bigdecimal (1.2.6)

executable-hooks (1.3.2)
gem-wrappers (1.2.7)

我的Capfile內容是

require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

最后，我的deploy.rb包含以下數據。

我收到以下錯誤

Answer 1

只需在服務器上嘗試gem install bundler一次就可以將bundle裝入rvm gemset，因為它不在你的gem list 。

通常，嘗試確保在通過ssh登錄服務器時運行bundle命令。 Capistrano不做魔術，它只是通過ssh登錄並發出命令。 你可以隨時查看capistrano發出的命令，比如你的例子cd /var/www/apps/oxygen/releases/20150803172155 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/oxygen/shared/bundle --without development test --deployment --quiet並在出現故障時自己嘗試。

Answer 2

確保在正確的gemset中安裝了bundler。

我收到了這個錯誤，並且因為捆綁器安裝在默認的gemset中而感到頭疼，但它不是我用於我的rails應用程序的那個。

當我意識到它時，我就像，“哇！”

只是想我會在這里發布，希望它會幫助別人。

Answer 3

這對我來說不起作用， gem install bundler

我意識到我沒有正確設置deploy.rb文件。

因為我使用RVM，我檢查了rvm list中的ruby版本

   jruby-1.7.19 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]

然后配置我的deploy.rb文件set :rvm_ruby_version, 'ruby-2.2.1'

Answer 4

在您的服務器上

rvm 2.2.2@gemset-name do gem install bundler
