bundle exec - 你已经激活了json X,但是你的Gemfile需要json Y

标签: json rubygems bundler

尽管使用了 bundle exec 前缀,但是当我收到此错误时,尝试在Windows上执行gegwin(x64)上的jekyll。

执行时不应激活Gemfile中定义的依赖关系(即1.8.6)吗?

对这里出了什么问题的想法?我对Ruby宝石的世界全新。我查看了其他“你已经激活了......”帖子显示了类似的消息,但那里的答案并没有解决我的问题。

$ bundle exec jekyll serve

$ bundle exec jekyll serve
/cygdrive/c/Users/mochapenguin/.rvm/gems/ruby-2.4.0/gems/bundler-1.14.6/lib/bundler/runtime.rb:40:in
 `block in setup': You have already activated json 2.0.2, but your Gemfile requires json 1.8.6. 
 Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

我不知道问题到底是什么,但是我将Gemfile减少到了这个并且它不会落入堆中。当这些特定的版本依赖关系没有得到强制执行时,它可能会以某种方式运行。

source 'https://rubygems.org'

# sample suggested [here](https://jekyllrb.com/docs/github-pages/) and in github help
gem 'github-pages', group: :jekyll_plugins

此问题与bundler和系统宝石突出显示at Gem Versioning and Bundler - Doing it right

  

Bundler的沙箱依赖于它在Ruby进程一开始就存在的能力,因此能够确保所有已加载库的版本都能反映Gemfile.lock中列出的版本。通过运行系统可执行文件,您可以在Bundler修改加载路径并替换正常的Rubygems加载机制之前执行Ruby代码,从而允许任意非托管gem加载到内存中。 一旦发生这种情况,所有投注均已关闭。

这种情况似乎正在发生。

但是,如上所述 - 无法卸载系统json 2.0.2 gem。

答案 0 :(得分:6)

游戏有点晚了,但是,嘿,我有一个解决方案!这就是我这样做的方式:所以除了查看安装宝石的标准位置外,还有一个地方可以明显地“定义”宝石,并将其带入系统。我使用rbenv安装东西(我建议通过RVM),这些是我的目录:

/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/gems
/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/specifications/default

在您的情况下,您的确切位置可能会有所不同,但您应该能够弄明白。如果某个宝石位于标准位置(/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/gems),您就可以毫无问题地进行“宝石卸载”。对于其他位置,虽然......很难。要简单地阻止系统版本被识别以便您可以使用Gemfile中的版本,只需将json-X.gemspec文件从其他位置的第二个目录(上面的/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/specifications/default)移开。就是这样!

答案 1 :(得分:-4)

昨天我遇到了同样的问题。我不是专家,但以下工作对我有用:

我使用Jekyll创建了一个新网站:

$ jekyll new "name_site" 

然后我将新的GemFile和GemFile.lock从新文件夹复制到较旧的文件夹(您遇到问题)。然后,你运行:

$ jekyll serve 

在您当前网站的文件夹中,它应该有效。让我知道它是否适合你!
