Ruby on rails 安装nokogiri（1.6.0）时出错，Bundler无法继续

我试图打开rails控制台，但发现如下错误：

rails c
Could not find nokogiri-1.6.0 in any of the sources
Run `bundle install` to install missing gems.

然后我运行

包安装

希望有人能帮助我！谢谢。

我删除了

Gemfile.lock

，然后运行

捆绑安装

。一切都好！：）

To dosudo-apt-get-install-build基本补丁ruby-dev-zlib1g-dev-liblzma-dev 然后再次尝试安装

运行

$ sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev

然后

我犯了这个错误，这就是我的工作原理：

bundle config build.nokogiri --use-system-libraries
bundle install

您在Gemfile.lock中使用了不同的nokogiri版本。是的，我发现了两个版本：

nokogiri（~>1.4）

，

nokogiri（1.6.0）

尝试将Gemfile.lock 1.4编辑为1.6.0，然后再次运行bundle安装。仍然存在相同的错误，我是否应该将nokogiri 1.6.0更改为其他版本？是的。应删除Gemfile.lock。删除Gemfile.lock会使您丢失对已安装gems的任何引用，如果Gemfile中没有正确说明，更新版本可能会破坏某些代码。只有在允许您中断代码时才可以执行此操作。删除Gemfile.lock和bundle安装工作正常。谢谢。你能分享一下删除这个Gemfile.lock的步骤吗？（我有很多Gemfiles…）@A.Trejo项目的根目录添加一个“为什么？”如何？我们正在这样做？添加一个“为什么？”如何？我们正在这样做？

$ sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev

$ gem install nokogiri

bundle config build.nokogiri --use-system-libraries
bundle install
