Capistrano bundler：安裝失敗

Question

我試圖將我的rails應用程序部署到使用Capistrano 3.0的EC2實例中。我現在正在運行「cap production deploy」或「cap production bundler：install」時出現的以下輸出。

當SSH-ING到服務器並運行相同的命令（「CD /無功/網絡/應用/電流& &的/ usr/bin中/ env的束--gemfile /無功/網絡/應用/電流/ Gemfile --path/var/www/app/shared/bundle --deployment --verbose --binstubs/var/www/app/shared/bin --without development test「）似乎都沒問題...

對此非常絕望...... 謝謝！

線條

DEBUG [f15c9f08] Command: cd /var/www/app/current && /usr/bin/env bundle --gemfile /var/www/app/current/Gemfile --path /var/www/app/shared/bundle --deployment --verbose --binstubs /var/www/app/shared/bin --without development test 
DEBUG [f15c9f08] /usr/bin/env:

指示捆綁沒有找到，或者未安裝。 Capistrano（在此記錄爲http://www.capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/）運行在非登錄非交互式外殼中。

我猜測bundler安裝在特殊路徑中，或者您正在使用rvm，chr​​uby或rbenv。而且，由於Capistrano正在使用的非登錄非交互式會話，因此這些內容不會像初始化時那樣進行初始化。

解決方案是使用capistrano-{rvm,chruby,rbenv}適合您的環境的寶石，如Capfile中所述。

如果不使用這些版本的經理之一，試試這個：

ssh me@theserver 'which bundler' 

也許你會看不到輸出（更多關於爲什麼在上面的鏈接），解決這個問題，並Capistrano的將工作。

Answer 2

bundlebundle可執行文件從系統中丟失或其PATH未知的shell。

檢查下面的測試：

系統可以找到perl可執行：

# /usr/bin/env perl 
^C << I did CTRL+C as perl was expecitng me to put some code 

現在，我的系統無法找到perlyo可執行文件，並引發錯誤：

# /usr/bin/env perlyo 
/usr/bin/env: perlyo: No such file or directory 

上面的錯誤是類似於你得到的/usr/bin/env bundle這是：

DEBUG [f15c9f08] /usr/bin/env: 
DEBUG [f15c9f08] bundle 
DEBUG [f15c9f08] : No such file or directory 

檢查系統是否知悉以下命令運行約bundle：

# which bundle 
# whereis bundle 

如果它不能與上面的命令找到，然後檢查是否bundle在所有存在於系統，如下：

# updatedb 
# locate bundle 

如果您找到bundle，請相應地添加它的path，以便您的shell可以識別它。

希望這會有所幫助。

Answer 3

這個問題確實與非交互式shell有關。

最後我不得不把下面一行添加到.bashrc：

source ~/.rvm/scripts/rvm 

萬一別人得到類似的問題，我會補充一點，我也不得不映射rake命令所以它會正常工作。注意下列行添加到我的deploy.rb文件：

SSHKit.config.command_map[:rake] = "bundle exec rake" 

Answer 4

你最好使用Capistrano的-rbenv寶石來管理你的ROR ENV

1. 添加gem 'capistrano-rbenv', '~> 2.0' to your的Gemfile
2. 取消註釋require 'capistrano/rbenv'在capfile;如果capistrano/bundler評論，取消它也
3. 設置rbenv_ruby變量set :rbenv_ruby, '2.0.0-p247'在部署文件

那麼所有的設置！

Answer 5

我能夠通過添加以下代碼在〜/ .bashrc來解決這個問題：

export RBENV_ROOT="${HOME}/.rbenv" 

if [ -d "${RBENV_ROOT}" ]; then 
    export PATH="${RBENV_ROOT}/bin:${PATH}" 
    eval "$(rbenv init -)" 
fi 

Answer 6

我有點晚來回答這個問題，但它可能會幫助一些用戶喜歡我。

如果您使用rbenv然後通過添加以下行deploy.rb

set :default_env, { path: "~/.rbenv/shims:~/.rbenv/bin:$PATH" }

Answer 7

設置你的rbenv的默認環境作爲@zpieslak說：

：

在〜/ .bashrc添加此

if [ -d "${RBENV_ROOT}" ]; then 
    export PATH="${RBENV_ROOT}/bin:${PATH}" 
    eval "$(rbenv init -)" 
fi 

在此行之前：

# If not running interactively, don't do anything 
case $- in 
    *i*) ;; 
     *) return;; 
esac
