如何将Cocoapods降级到旧版本,或者如何安装旧版本的Cocoapods？

我用过sudo bundle install,这可能是问题的原因？

我现在有:

• gem -v 2.6.14
• ruby -v ruby 2.3.5p376(2017-09-14修订版59905)[x86_64-darwin15]
• jekyll -v jekyll 3.6.2
• bundle -vBundler版本1.16.0.pre.3

我试图运行bundle exec jekyll serve或只是遇到以下错误jekyll serve

/Users/myusername/.rvm/rubies/ruby-2.3.5/lib/ruby/site_ruby/2.3.0/rubygems.rb:271:in cd my_pathactivate_bin_path'from /Users/myusername/.rvm/gems/ruby-2.3. 5/bin/bundle:23:in sudo bundle installeval'from /Users/myusername/.rvm/gems/ruby-2.3.5/bin/ruby_executable_hooks :15: in`

此外,当访问我有我的博客的文件夹时,gem -v我收到以下消息:

VM使用你的Gemfile来选择Ruby,它很好 - Heroku也这样做,你可以用'rvm rvmrc warning ignore/Library/WebServer/Documents/blog/Gemfile'忽略这些警告.要忽略所有文件的警告,请运行'rvm rvmrc warning ignore allGemfiles'.未知的ruby解释器版本(不知道如何处理):RUBY_VERSION.

我不知道如何解决这个问题.我只是想创建我的静态博客,说实话,我不知道Ruby,Gem或Bundle :)所以我很感激一些见解!

我尝试克隆这个仓库并运行bundle install.捆绑过程失败并抛出此错误:

我有一台白色Macbook,我必须在10个小时内参加一个会议,但我遇到了很多问题.

首先,我想要Rails 3,所以我使用MacPorts来安装Ruby 1.8.7.它工作得很好;)然后我想我应该安装Rails 3,但不,不!它说:

$ sudo gem install rails --pre

ERROR: Error installing rails:


            activesupport requires Ruby version >= 1.8.7.
