我如何使用冷冻Capistrano？ [英] How do I use frozen Capistrano?

问题描述

Backstory

我在Rails 2.1上，需要将Capistrano gem冻结到我的供应商文件夹中（因为我的主机已经打破了它们的上限gem依赖关系，让我自己尽可能独立）。

在我本地的Windows机器上，我放置了以下我的environment.rb

  config.gemcapistrano，：version => 2.5.2
 config.gemnet-ssh，：lib => net / ssh，：version => 2.0.4
 config.gemnet-scp，：lib => net / scp，：version => 1.0.1
 config.gemnet-sftp，：lib => net / sftp，：version => 2.0.1
 config.gemnet-ssh-gateway，：lib => net / ssh / gateway，：version => 1.0.0
  

宝石已经安装完毕，所以我冻结了它们。检查...

 >耙宝石
 ... 
 [F] capistrano = 2.5。 2 
 [F] net-ssh = 2.0.4 
 [F] net-scp = 1.0.1 
 [F] net-sftp = 2.0.1 
 [F] net-ssh-gateway = 1.0.0 
  

然后我在本地提交SVN并在prod Linux上更新。

问题

当我尝试运行我的Capistrano冻结版本时，出现以下错误。 / p>

  $ ./vendor/gems/capistrano-2.5.2/bin/cap deploy-with-migrations 
 ./ vendor / gems / capistrano-2.5.2 / bin / cap：3：在`require'中：不需要这样的文件来加载--capistrano / cli（LoadError）
 from ./vendor/gems/capistrano-2.5.2 / bin / cap：3 
  

任何想法我做错了？

解决方案

你没有做错任何事情。您看到这个问题是因为 capistrano / bin / cap 下的 cap 文件并不打算作为一个独立的。如果您尝试从主宝石文件夹运行它，您会看到相同的结果。 cap 可执行文件（在标准linux安装中存储在 / usr / bin / cap ）需要 ruby​​gems ，注册capistrano和，然后加载 capistrano / bin / cap 文件。

解决这个问题的方法是在你的capistrano / bin / cap文件中添加 require'rubygems'：

 ＃！/ usr / bin / env ruby​​ 
 require'rubygems'
 require'capistrano / cli' 
 Capistrano :: CLI.execute 
  

如果您不想修改 capistrano / bin / cap 当您使用-r标志运行它时，可以特别包含rubygems库。您给定的命令如下所示：

  $ ruby​​ -r ruby​​gems ./vendor/gems/capistrano-2.5.2/bin / cap deploy-with-migrations 
  

Backstory

I'm on Rails 2.1 and need to freeze the Capistrano gem to my vendor folder (as my host has broken their cap gem dependencies and I want to make myself as independent as possible).

On my local windows machine I've put the following my environment.rb

config.gem "capistrano", :version => "2.5.2"
config.gem "net-ssh", :lib => "net/ssh", :version => "2.0.4"
config.gem "net-scp", :lib => "net/scp", :version => "1.0.1"
config.gem "net-sftp", :lib => "net/sftp", :version => "2.0.1"
config.gem "net-ssh-gateway", :lib => "net/ssh/gateway", :version => "1.0.0"

The gems were already installed and so I froze them. Checking ...

>rake gems
...
[F] capistrano = 2.5.2
[F] net-ssh = 2.0.4
[F] net-scp = 1.0.1
[F] net-sftp = 2.0.1
[F]net-ssh-gateway = 1.0.0

I then commit to SVN locally and update on the prod Linux box.

Problem

When I try and run my frozen version of Capistrano I get the following error.

$ ./vendor/gems/capistrano-2.5.2/bin/cap deploy-with-migrations 
./vendor/gems/capistrano-2.5.2/bin/cap:3:in `require': no such file to load --capistrano/cli (LoadError)
    from ./vendor/gems/capistrano-2.5.2/bin/cap:3

Any ideas what I've done wrong?

解决方案

You haven't done anything wrong. You're seeing this issue because the cap file under capistrano/bin/cap isn't meant to be run as a stand-alone. You'll see the same result if you try to run it from your primary gem folder. The cap executable (stored at /usr/bin/cap on a standard linux install) requires rubygems, registers capistrano and then loads the capistrano/bin/cap file.

One solution to this would be to add require 'rubygems' to your capistrano/bin/cap file:

#!/usr/bin/env ruby
require 'rubygems'
require 'capistrano/cli'
Capistrano::CLI.execute

If you don't want to modify capistrano/bin/cap you could specifically include the rubygems library when you run it using the -r flag. Your given command would look like this:

$ ruby -r rubygems ./vendor/gems/capistrano-2.5.2/bin/cap deploy-with-migrations
