从窗口上的耙子任务执行 berks 命令时捆绑器错误

Question

我写了一个 rake 任务来在子目录中的 Berksfile 上执行 berks package 命令：

task :cook do
  `berks package ./cookbooks.tar.gz -b ./cookbook/Berksfile`
end

我也尝试了这些变体：

task :cook do
  `.\scripts\berks_package.bat` # containing stuff
end
task :cook do
  `C:\opscode\chefdk\embedded\bin\ruby.exe "C:\opscode\chefdk\bin\berks" package ..\cookbooks.tar.gz -b ..\cookbook\Berksfile`
end

无论我以何种方式执行 berks，任务都会失败并显示以下错误：

C:/tools/ruby213/lib/ruby/gems/2.1.0/gems/bundler-1.7.9/lib/bundler/resolver.rb:434:in `version_conflict': Bundler could not find compatible versions for gem "nokogiri": (Bundler::VersionConflict)

从命令提示符执行berks package ./cookbooks.tar.gz -b ./cookbook/Berksfile的工作方式与在任务中执行其他正常系统命令相同。

Answer 1

我在写问题时发现了问题，并偶然发现了新的想法。

根本问题是与 ChefDK 一起安装的 Ruby 二进制文件和 gem 与 Ruby 的系统安装冲突。具体来说，耙子任务是在系统Ruby安装下执行的，但是当berks被执行时，它在嵌入式的ChefDK Ruby下运行。我不清楚下一部分，但似乎 ChefDK Ruby 知道 Gemfile 并试图解决依赖项本身，但由于 nokogiri 无法由 Windows 上的捆绑器解析（即构建）而不会感到痛苦，它失败了。

这是我为解决问题所做的工作：

1. 卸载了系统红宝石
2. 向系统 PATH 变量添加了C:opscodechefdkbin，以便我可以运行红宝石、耙子、宝石、捆绑包等。
3. Ran gem install nokogiri（现在在ChefDK的Ruby下执行）
4. 通过运行bundle install重新创建了 Gemfile.lock 文件
5. 用Bundler.with_clean_env块包围了 berks 系统调用（这是关键！
   • 多亏了这个问题

该任务现在如下所示：

task :cook do
  Bundler.with_clean_env do
    `berks package cookbooks.tar.gz -b .\cookbook\Berksfile`
  end
end
