无法在 ruby Gemfile 中包含 'git' gem

Question

我是 ruby 的新手，我创建了一个使用 Git gem 的脚本。 (require 'git')。我必须对 jenkins 执行此脚本，为此我添加了 Gemfile 和 Gemfile.lock，条目如下：

Gemfile
source 'https://rubygems.org'
gem 'pg'
gem 'git', '~> 1.3'

Gemfile.lock
GEM
  remote: https://rubygems.org/
  specs:
    pg (0.18.4)
    git (1.3.0)

PLATFORMS
  ruby

DEPENDENCIES
  pg
  git

当尝试使用以下命令通过 jenkins 执行脚本时：

#!/bin/bash -l
rvm use 1.9.3
bundle install --gemfile Gemfile --deployment
bundle exec ruby processMetadata.rb

请帮我解决下面提到的错误：

Using /usr/local/rvm/gems/ruby-1.9.3-p551
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

You have added to the Gemfile:

You have deleted from the Gemfile:

If you haven't changed sources, that means the author of git (1.3.0) has removed it. You'll need to update your bundle to a different version of git (1.3.0) that hasn't been removed in order to install. (Bundler::GemNotFound)

Answer 1

您似乎手动制作了 Gemfile.lock 文件。这通常不需要，因为该文件是由 bundle 自动生成的。它基本上包含捆绑器为您下载的确切版本号。

Bundle，当运行处于部署模式 (--deployment) 时，将检查您的两个文件，如果它们之间存在任何不匹配，将拒绝运行，或者如果 Gemfile.lock 文件需要任何更新。这是作为健全性检查完成的，因为这些文件应该在开发期间同步制作，而不是在生产期间制作。

尝试删除 Gemfile.lock，然后重新开始。由于您需要使用的版本号已经存在于您的 Gemfile 中，因此应该可以毫无问题地生成正确的 Gemfile.lock。另外，一开始不要在 --deployment 模式下运行它，因为那样不会生成 Gemfile.lock 文件。

所有这些步骤实际上都记录在您从捆绑程序收到的错误消息中：

You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

请注意，之后生成的 Gemfile.lock 文件仍然很重要（它包含您正在使用的确切版本），并且应该是您存储库的一部分。

您可能遇到的另一个问题是您仍在使用 ruby 1.9，因此您还必须修复 Gemfile 中的 pg gem 版本像这样：

source 'https://rubygems.org'
gem 'pg', '~> 0.18.4'
gem 'git', '~> 1.3'

结果 Gemfile.lock 将是这样的：

GEM
  remote: https://rubygems.org/
  specs:
    git (1.3.0)
    pg (0.18.4)

PLATFORMS
  ruby

DEPENDENCIES
  git (~> 1.3)
  pg (~> 0.18.4)
