无法在Windows上使用Rails 3安装Mongoid [英] Trouble installing Mongoid with Rails 3 on Windows

问题描述

在我的Gemfile中:

In my Gemfile:

gem "mongoid", "~> 2.3"
gem "bson_ext", "~> 1.4"

当我运行bundle install时，出现以下错误:

When I run bundle install I get the error below:

Bundler could not find compatible versions for gem "activemodel":
  In Gemfile:
    mongoid (~> 2.3) x86-mingw32 depends on
      activemodel (~> 3.1) x86-mingw32

    rails (= 3.0.6) x86-mingw32 depends on
      activemodel (3.0.6)

正如其他文章所建议的那样，我尝试指向该版本的github，但是当我这样做并运行bundle install时，出现另一个错误:

I've tried pointing to github for the version, as is suggested in some other posts, but when I do this and run bundle install, I get another error:

任何提示都值得赞赏.谢谢！

Any tips are appreciated. Thanks!

推荐答案

如果我没记错的话，bson_ext需要本地构建.这意味着您必须以某种方式在Windows上构建它.错误指向x86-mingw32，可以从此处

If I recall correctly, bson_ext needs to be built natively. This means that somehow you must build it on Windows. The errors are pointing to x86-mingw32, which can be downloaded from here

之所以需要它，是因为有一些库依赖于平台.希望这能为您指明正确的方向.

The reason you would need that is because there are a couple of libraries that are platform dependent. Hope this sets you in the right direction.
