Question

添加我的Gemfile后，我在捆绑安装中：

gem 'pg',  '0.20.0'
gem 'fog', '1.42'
gem 'rails_serve_static_assets'
gem 'rails_stdout_logging'

但在安装ovirt-engine-sdk（4.2.3）时出错后Bundler无法继续。日志说：

find_executable: checking for xml2-config... -------------------- no --------------------
package configuration for libxml2 is not found

我在Windows 10上，完全迷失了我在此处找到的说明https://github.com/GNOME/libxml2/tree/master/win32

由于某些原因需要此库，但不是上面列出的4个宝石。无论如何我需要它！

这是我的Gemfile：

    source 'https://rubygems.org'

    git_source(:github) do |repo_name|
      repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
      "https://github.com/#{repo_name}.git"
    end


    gem 'rails', '~> 5.1.5'
    gem 'puma', '~> 3.7'
    gem 'sass-rails', '~> 5.0'
    gem 'uglifier', '>= 1.3.0'
    gem 'coffee-rails', '~> 4.2'
    gem 'turbolinks', '~> 5'
    gem 'jbuilder', '~> 2.5'
    gem 'devise', '~> 4.4', '>= 4.4.1'
    gem 'activeadmin', '~> 1.2', '>= 1.2.1'
    gem 'inherited_resources'
    gem 'active_skin'
    gem 'paperclip', '~> 6.0.0'
    gem 'cancancan'


    group :development, :test do
      # Use sqlite3 as the database for Active Record
      gem 'sqlite3'
      # Call 'byebug' anywhere in the code to stop execution and get a debugger console
      gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
      # Adds support for Capybara system testing and selenium driver
      gem 'capybara', '~> 2.13'
      gem 'selenium-webdriver'
    end

    group :development do
      # Access an IRB console on exception pages or by using <%= console %> anywhere in the code.
      gem 'web-console', '>= 3.3.0'
    end

    group :production do
      gem 'pg',  '0.20.0'
      gem 'fog', '1.42'
      gem 'rails_serve_static_assets' # for Static Assets on Heroku 
      gem 'rails_stdout_logging' # needed with the above one
    end

    # Windows does not include zoneinfo files, so bundle the tzinfo-data gem
    gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

Answer 1

我已经将config / application.rb config.serve_static_assets = true中此行所引发的问题与生产中的heroku一起添加。

Answer 2

我在新的ubuntu 18.04上安装了Rails项目时遇到了完全相同的问题。

报告了类似的问题here

所以对我来说是解决方法

sudo apt-get install libxml2-dev

然后我用libcurl得到了一个类似的问题，并用

进行了修复

sudo apt-get install libcurl4-openssl-dev

然后我用pg修复了一个问题

sudo apt-get install libpq-dev来自here

找不到libxml2的包配置
