如何修复:Bundler 找不到 gem "nokogiri" 的兼容版本
how to fix : Bundler could not find compatible versions for gem "nokogiri"
我是 ruby 的新手,我正在尝试 运行 我的第一个应用程序,但是当我启动服务器时出现此错误:
Bundler could not find compatible versions for gem "nokogiri": In Gemfile:
capybara (>= 2.15) x86-mingw32 was resolved to 3.15.1, which depends on
nokogiri (~> 1.8)
Could not find gem 'nokogiri (~> 1.8)', which is required by gem 'capybara (>= 2.15)', in any of the sources.
我尝试了很多解决方案并且 none 成功了,例如我尝试了 bundle install
bundle update
bundle exec
我有 ruby 版本 2.3.3,
rails 版本 5.1.7 当我从应用程序文件夹外部 运行 rails -v
时,但从内部我得到与上面相同的错误
这里是 gem 文件:
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"

请 post 您的 Gemfile.lock
确认 - 但这看起来水豚版本被锁定为 '>=2.15' 并且 [=16] 中不存在与之兼容的 nokogiri 版本=].
一个快速解决方法是在您的 Gemfile 中将 nokogiri 显式设置为 'nokogiri', '~> 1.8'
并查看问题是否仍然存在。您可能想要升级您的水豚版本以匹配与其他需要它的 gem 兼容的 nokogiri 版本
最后按照以下步骤解决了问题:
- 卸载 rails 安装程序并手动删除文件夹。
- 设置 ruby 安装程序。
- 运行
gem install rails
- 安装纱线。
- 重启电脑
- 运行
rails webpacker:install
