無法在Ruby Gemfile中包含“ git”寶石

Question

我是紅寶石的新手，並創建了一個使用Git gem的腳本。 （ require 'git' ）。 我必須對jenkins執行此腳本，並為其添加了Gemfile和Gemfile.lock ，條目如下：

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

當嘗試使用以下命令通過jenkins執行腳本時：

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

請幫助我解決以下提到的錯誤：

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:
* git (~> 1.3)

You have deleted from the Gemfile:
* git

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

看起來您是手工制作的Gemfile.lock文件。 通常不需要使用此文件，因為該文件是由bundle自動生成的。 它實質上包含捆綁程序為您下載的確切版本號。

捆綁軟件在部署模式（ --deployment ）中運行時，將檢查兩個文件，並且如果它們之間存在任何不匹配，或者Gemfile.lock文件是否需要任何更新，則將拒絕運行。 這是作為完整性檢查來完成的，因為這些文件應在開發期間而不是在生產期間同步進行。

嘗試刪除Gemfile.lock ，然后重新開始。 由於您需要使用的版本號已經存在於您的Gemfile ，因此應該可以正確Gemfile.lock而不出現任何問題。 同樣，首先不要在--deployment模式下運行它，因為那樣不會生成Gemfile.lock文件。

您從捆綁程序收到的錯誤消息中實際上記錄了所有這些步驟：

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.

請注意，之后生成的Gemfile.lock文件仍然很重要（它包含您正在使用的確切版本），並且應成為存儲庫的一部分。

您可能還會遇到的另一個問題是，您仍在使用ruby 1.9，因此還必須像這樣修復Gemfile的pg gem版本：

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

生成的Gemfile.lock將如下所示：

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

PLATFORMS
  ruby

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