Question

我正在尝试部署我的应用程序“项目”。它是用Rails用Ruby编写的，它说我需要将Ruby从2.5.1降级到2.4.0。我尝试在终端中混合修改Gemfile和一些RVM命令，但似乎无济于事。 SOS请发送帮助！

我将Gemfile中的ruby v更改为“ 2.4.0”，当我进入目录时，它通知我：

Using: /Users/me/.rvm/gems/ruby-2.4.0@rails3

然后我尝试运行“ rails s”并收到：

根据描述和共享的日志，似乎您已更改了ruby版本，但未在修改后的版本上构建gemset。

下面提到的日志记录表明无法找到特定Ruby版本（2.4.0）的捆绑软件

/Users/brianna/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

尝试以下步骤：

1）使用安装与ruby 2.4.0对应的捆绑器

gem install bundler

2）现在，删除Gemfile.lock并运行以下命令：

bundle install

或者尝试运行

bundle update

3）请注意，如果指定了与ruby> = 2.5兼容的特定版本的任何宝石，则可能必须删除指定与ruby 2.4.0兼容的版本的版本号

希望有帮助！

您正在尝试安装Nokogiri gem，这要求您首先安装一些依赖库并在本地计算机上构建一段时间。为此，您可以按照以下指南安装nokogiri。
