Nokogiri本机扩展无法构建（不是libxml2或libxslt缺少问题）: 正如标题所说，它似乎没有失败，因为缺少libxml2或libxslt。我不确定该怎么做错误。（得到它？因为问题出在制作期间？嘿嘿……） Anywho，这是我得到的输出。任何想法，将不胜感激： Building native extensions. This could take a while… ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb extconf.rb:10: Use RbConfig instead of obsolete and deprecated Config. checking for libxml/parser.h… yes checking for libxslt/xslt.h… yes checking for libexslt/exslt.h… yes checking for iconv_open() in iconv.h… yes checking for […]

我可以有条件地跳过在同一个文件中加载“更多”ruby代码吗？: 我可以有条件地跳过在同一个文件中加载“更多”ruby代码，如果找不到库（通过require加载）？ begin require ‘aws-sdk’ rescue LoadError puts “aws-sdk gem not found” return #does not work. nor does next end # code after here should not be executed as `aws-sdk` gem was not found puts “=== should not get executed” namespace :db do desc “import local postgres database to heroku. user and database name is […]

如何使用bundler创建相互依赖的gem，并使用存储库作为源？: 如何创建相互依赖的gem，仍然使用Bundler？现在，如果library-a Gemfile如下所示： gem ‘library-b’ gem ‘library-c’ 并且library-b的Gemfile读取如下： gem ‘library-a’ gem ‘library-c’ 并且library-c的Gemfile读取： gem ‘library-a’, github: ‘library-root/library-a’, branch: ‘master’ gem ‘library-b’, github: ‘library-root/library-b’, branch: ‘master’ 当您尝试为library-c运行bundle update和/或bundle install ，这是输出： Your Gemfile requires gems that depend depend on each other, creating an infinite loop. Please remove either gem ‘library-a’ or gem ‘library-b’ and try again. 对于library-a或library-b将发生相同消息的变体。 […]

Rails :: Railtie：无法创建Rails 3 gem: 我真的可以用另一套眼睛，所以我想我会把它贴在这里。不久前我为自己的教育目的写了一个基本的ActiveRecord扩展。我最近一直在阅读有关Railties的内容，并认为我会尝试使用Rails 3.我想我会把它打包成一块gem来了解这个过程。如果我跳过Railtie并在初始化文件夹中将其作为传统的monkeypatch执行，它可以正常工作。使用铁路……没什么。从它的外观来看，我的Railtie永远不会被执行，因此似乎没有其他任何事情发生。这里有人看错了吗？我们也欢迎任何有关最佳实践或改进的建议。项目Gemfile： gem ‘sql_explain’, :path => “/home/mike/projects/sql_explain/” gemspec： … spec.files = %w(README.rdoc sql_explain.rb lib/sql_explain.rb lib/railtie.rb sql_explain.gemspec) … sql_explain.rb require ‘lib/railtie.rb’ railtie.rb require ‘active_record’ require ‘sql_explain’ module SqlExplain class Railtie < Rails::Railtie railtie_name :sql_explain initializer 'sql_explain.extend.activerecord' do if defined?(ActiveRecord) ActiveRecord::ConnectionAdapters::MysqlAdapter.include SqlExplain::AR end end end end sql_explain.rb module SqlExplain […]

尝试运行gem install时出错: 我正在尝试在我的开发服务器上运行并运行。这是一个fedora14盒子。我安装了rvm，ruby 1.8.7和rubygems 1.6.2。当我尝试通过gem， gem install rails ，我收到以下错误： ERROR: Loading command: install (LoadError) no such file to load — zlib ERROR: While executing gem … (NameError) uninitialized constant Gem::Commands::InstallCommand 关于发生了什么的任何想法。我是ruby / rubygems / rails的100％新手，我对Linux有足够的了解，所以任何帮助/建议都会非常感激。提前致谢

如何在gem环境中设置正确的Ruby版本: 注意：这个问题涉及如何让bundler使用chruby和.ruby-version设置的Ruby版本？。使用chruby我在macOS上安装了Ruby 1.8.7： $ ruby -v ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin17.4.0] 另外，我使用gem update –system 1.8.30安装特定版本的RubyGems，我希望它是兼容的。这似乎安装正确： $ gem –version 1.8.30 但是，我的RubyGems环境显示了不正确的Ruby版本（2.5.0）： $ gem env RubyGems Environment: – RUBYGEMS VERSION: 1.8.30 – RUBY VERSION: 2.5.0 (2017-12-25 patchlevel 0) [x86_64-darwin17] – INSTALLATION DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7 – RUBY EXECUTABLE: /usr/local/opt/ruby/bin/ruby – EXECUTABLE DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7/bin – RUBYGEMS PLATFORMS: […]

Nokogiri 1.5.2无法在Ubuntu 11.10上安装: 真的很快，我知道一个类似的问题。但是，遵循最高评级的答案是行不通的。我已经重新启动了我的系统和终端，但无济于事。出于某种原因，Nokogiri没有意识到我安装了libxslt1-dev ，虽然我明确安装了它，但是使用了sudo apt-get install libxslt-dev和sudo apt-get install libxslt1-dev 。这是输出; 我错过了什么吗？ $ gem install nokogiri -v ‘1.5.2’ Building native extensions. This could take a while… ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. ~/.rvm/rubies/ruby-1.9.3-p125/bin/ruby extconf.rb extconf.rb:10: Use RbConfig instead of obsolete and deprecated Config. checking for libxml/parser.h… yes […]

在我的mac上更新gem – 安装了两个版本的bundler: 我在RVM之前和之后安装了我的本地机器上的大量gem，所以我决定将它们全部擦除并重新安装。一切似乎都没问题，除了捆绑： gem list ….. bundler (1.1.3, 1.0.22) 我不知道为什么1.0.22仍然存在，我无法弄清楚如何摆脱它！ $ gem cleanup Cleaning up installed gems… Attempting to uninstall bundler-1.0.22 Unable to uninstall bundler-1.0.22: Gem::InstallError: gem “bundler” is not installed Clean Up Complete $ gem uninstall bundler-1.0.22 INFO: gem “bundler-1.0.22” is not installed 更新安德鲁要求的路径信息 /Users/brandon/.rvm/gems/ruby-1.9.3-p125-perf@global/gems/bundler-1.0.22/
