Javascript Bundler 2.0.2和Jekyll/Gulp已安装，但仍获得；必须使用捆绑机2或更高版本；消息

我遇到了一个问题，Jekyll/Gulp安装失败，我不断收到的信息是“必须使用Bundler 2或更高版本”，即使我安装了Bundler 2.0.2。还有其他类似的问题，但这些项目是基于Rails和Heroku的。到目前为止，我找到的解决方案中没有一个不适合我

终端显示我安装了与Gemfile.lock中列出的相同版本的Bundler

fs-217-156:jekyll-gulp mrjandre$ bundler -v
Bundler version 2.0.2

我正在运行Ruby 2.6.5：

fs-217-156:jekyll-gulp mrjandre$ ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-darwin17]

从Gemfile.lock：

PLATFORMS
  ruby
  x64-mingw32

DEPENDENCIES
  jekyll (~> 3.8.5)
  jekyll-feed (~> 0.6)
  tzinfo-data

BUNDLED WITH
   2.0.2

在过去的几天里，我尝试卸载和重新安装Bundler和Jekyll至少十几次

gem uninstall bundler

不知道binstubs是什么，但我也尝试了一下：

bundle binstubs bundler

“大口喝”的结果：

我还删除了

node\u模块

，重新安装了这些依赖项几次，运行了

npm审计修复程序

，并更新了npm

我经常在MacOSX和Windows10之间切换，这种设置在这两个系统上已经可靠多年了。如果您有任何建议，我将不胜感激。如果我遗漏了什么，我很乐意提供更多信息

编辑：该问题于2019-10-30年得到解决

如果您按照安装了Jekyll，那么您通过自制获得了Ruby 2.6.5，那么根本的问题是自制（直到2019-10-30）错误地配置了RubyGems，使得Ruby或多或少无法加载任何新版本，例如

bundler

错误配置在于覆盖

/usr/local/ceral/ruby/2.6.5/lib/ruby/2.6.0/rubygems/defaults/operating_system.rb

中的

default_dir

，显然是试图将“标准”gem安装文件夹移动到

/usr/local/lib/ruby/gems/2.6.0

但是，

default\u目录

需要指向

/usr/local/ceral/ruby/2.6.5/lib/ruby/gems/2.6.0

，因为它包含带有默认gem规范的

specifications/default

文件夹。 如果无法从

Gem:：Specification:：default\u specifications\u dir

加载默认Gem，则RubyGems对

require

的覆盖将不会激活默认Gem的较新版本，即使已安装并找到它们，这将阻止加载bundler 2.0.2。非默认gems（如Jekyll）仍按预期加载

由于自制RubyGems配置错误，导致的问题是路径中的

bundler

命令将是用户安装的v2.0.2，因为您执行了

gem安装--user install bundler jekyll

，并将用户安装路径（

$HOME/.gem/ruby/2.6.0/bin

）添加到了$path中，然而，由于配置错误，

jekyll

命令只能看到并使用默认的绑定器gem v1.17.2，而这些版本不匹配会导致您的问题

等待自制软件修复Ruby公式，您可以用以下内容替换operating_system.rb中的错误配置

module Gem
  class << self
    alias :old_default_dir :default_dir
    alias :old_default_path :default_path
    alias :old_default_bindir :default_bindir
    alias :old_ruby :ruby
  end

  def self.homebrew_gems_dir
    path = [
      "/usr/local",
      "lib",
      "ruby",
      "gems",
      "2.6.0"
    ]
    File.join(*path)
  end

  def self.default_path
    path = []
    path << homebrew_gems_dir
    path << user_dir if user_home && File.exist?(user_home)
    path << default_dir
    path << vendor_dir if vendor_dir and File.directory? vendor_dir
    path
  end

  def self.default_bindir
    "/usr/local/lib/ruby/gems/2.6.0/bin"
  end

  def self.ruby
    "/usr/local/opt/ruby/bin/ruby"
  end
end
