我在rubyinstaller网站上尝试了所有Ruby版本。我还在railsinstaller网站上尝试了两个版本。我一直在使用不同版本的rubygems等同样的问题。

然而，当我执行“rails new my_app --skip-bundle”时，它可以工作，当我手动转到app文件夹并进行捆绑安装时，它也可以工作。创建应用程序时只是捆绑安装根本不起作用。

Answer 1

bundler

此错误仅表示您当前的Ruby版本缺少gem install bundler gem。

所以，你需要通过这样做来安装gem：

2.2.3

再试一次。

更新

如果您使用rvm来管理Ruby版本，请尝试执行以下操作以指定Ruby版本（rvm use 2.2.3）：

C:/Ruby22-x64/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:128:in require': cannot load such file -- bundler (LoadError))

查看错误消息（2.2.0，它使用的是Ruby 2.2.3，而不是{{1}}。

Answer 2

您没有安装捆绑包。要安装它，请运行$MatchFinal[$i] = preg_quote($MatchFinal[$i]);。就像K M Rakibul Islam所说的那样，你必须确保为每个版本的ruby安装了捆绑器。因此，您需要为ruby版本2.2.0安装bundler。

Answer 3

我也遇到过Ubuntu和OS X的这个问题，我尝试将rails恢复到4.2.4，它第一次工作，但之后错误仍然存在。我通常可以在新创建的应用程序中“捆绑”或“捆绑安装”这一奇怪的事情。

我尝试过玩弄一切; rbenv，ruby，rails，bundler等都没有用。我正如你所说的那样恢复了Rubygem版本，它就像一个魅力！

谢谢！：）
