Ruby on rails can'；找不到宝石绑定器Ruby

使用MacOS13，rbenv

据我所知，它与Ruby版本有关，但我不知道如何解决这个问题。

看起来您可能需要执行

gem安装bundler

并让bundler gem启动并运行rails。

步骤（1）：安装bundler gem:

sudo gem install bundler

完成后，您将收到类似于以下内容的消息：

Fetching: bundler-1.16.1.gem (100%)
Successfully installed bundler-1.16.1
Parsing documentation for bundler-1.16.1
Installing ri documentation for bundler-1.16.1
Done installing documentation for bundler after 6 seconds
1 gem installed

步骤（2）：尝试检查捆绑程序版本：

bundle -v

您应该获得如下版本号：

Bundler version 1.16.1

步骤（3）：现在您可以使用bundle安装：

bundle install

我希望我的回答能有所帮助。

添加导致问题出错的命令Ruby 2.5在默认情况下会包括bundler gem，但在最后一分钟他们取消了它。所以现在，我们仍然需要在新的Ruby 2.5安装上执行

gem安装bundler

，然后才能执行

bundle安装

。顺便说一句，看起来您正在使用您的系统Ruby。您应该强烈地考虑使用Ruby环境管理器，比如“添加错误的命令”“我运行<代码> Rails新app Ap/代码>是的，我做了<代码> GEM安装Buffer-<代码>，我用RBEV安装了Ruby 2.5.0。你安装Ruby 2.3了吗？我怀疑ruby 2.5不是当前的默认版本。看起来它仍然可以访问2.3版：从/System/Library/Frameworks/Ruby.framework/Versions/2.3/Oh，我做了，但没有帮助。很高兴知道！如果你把你已经尝试过的事情的一些解决方案（和结果）包括在内，这会很有帮助。另外，@moveson推荐了一个版本控制/env管理器，比如rbenv或rvm，这非常有用。对不起，我应该这么说。我的错。到目前为止，我已经尝试了

gem安装bundler

，并且使用了rbenv。就这些，不用担心。在使用rbenv之前，您是否安装过ruby？如果运行

哪个捆绑包

，路径是什么？我刚刚重新安装了所有东西，现在就可以工作了。谢谢你的帮助。也许问题是我安装了Rails，之后又安装了新的Ruby版本的rbenv。永远不要使用sudo安装。@IulianOnofrei如果你说明了原因，而不仅仅是发出命令，你的评论会更有用。非常感谢。
