Rails 3-Bundler / Capistrano错误 [英] Rails 3 -- Bundler/Capistrano Errors

问题描述

我在开发箱上本地有一个基本的Rails 3应用程序，但是想要尽早测试部署以确保一切正常。我正在使用Capistrano进行部署。

I have a basic Rails 3 app working locally on my development box, but want to test out deploying early on to make sure everything works. I'm using Capistrano to deploy.

当我运行 cap deploy 时（在所有其他必要的设置之后），它会因以下错误而中断此命令：

When I run cap deploy (after all the other necessary setup), it breaks on this command with this error:

[...]
* executing 'bundle:install'
* executing "bundle install --gemfile /var/www/trex/releases/20100917172521/Gemfile --path /var/www/trex/shared/bundle --deployment --quiet --without development test"

servers: ["www.[my domain].com"]
[www.[my domain].com] executing command
** [out :: www.[my domain].com] sh: bundle: command not found
command finished
[...]

因此，它似乎在服务器上找不到 bundle 命令。

So it looks like it can't find the bundle command on the server.

但是，当我登录到服务器...

However, when I log in to the server...

$ ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]
$ rails -v
Rails 3.0.0
$ bundle -v
Bundler version 1.0.0

... 捆绑包命令运行正常。

...the bundle command works just fine.

出什么问题了？

（此外，出于完整性考虑：）

(Furthermore, for completeness:)

$ which ruby
~/.rvm/rubies/ruby-1.9.2-p0/bin/ruby
$ which rails
~/.rvm/gems/ruby-1.9.2-p0/bin/rails
$ which bundle
~/.rvm/gems/ruby-1.9.2-p0/bin/bundle

推荐答案

更新：

对于RVM> = 1.11.3，您现在应该使用< a href = https://github.com/wayneeseguin/rvm-capistrano rel = noreferrer> rvm-capistrano gem 。对于较旧的RVM> = 1.0.1，下面的答案仍然适用。

For RVM >= 1.11.3, you should now just use the rvm-capistrano gem. For older RVM >= 1.0.1, the answer below still applies.

原始答案：

好的，尽管我仍然还没有完全部署上限工作，我确实解决了 this 问题。问题是Capistrano尝试为Bundler（和其他gems）使用与RVM路径不同的路径。

Okay, though I still haven't gotten a full cap deploy to work, I did fix this problem. The problem was Capistrano trying to use a different path for Bundler (and other gems) than the RVM paths.

通过执行 cap检查Capistrano路径shell ，然后 echo $ PATH 。您可能会看到标准的 / usr / local / bin 和 / usr / bin ，但这不是RVM所在的位置

Check your Capistrano path by doing cap shell, then echo $PATH. You'll probably see your standard /usr/local/bin and /usr/bin, but that's not where RVM has Bundler, et al., stored.

编辑Capistrano config / deploy.rb 文件，然后添加每行这些说明：

Edit your Capistrano config/deploy.rb file, and add the following lines, per these instructions:

# Add RVM's lib directory to the load path.
$:.unshift(File.expand_path('./lib', ENV['rvm_path']))

# Load RVM's capistrano plugin.    
require "rvm/capistrano"

set :rvm_ruby_string, '1.9.2'
set :rvm_type, :user  # Don't use system-wide RVM

Capistrano终于见到了Bundler并开始适当地装载宝石。

That finally got Capistrano to see Bundler and start loading gems appropriately.
