Question

您好我正在使用Phusion Passenger和NGINX来运行RoR应用程序。但得到了这个错误 Phusion Passenger应用程序服务器尝试启动Web应用程序。但是应用程序本身（而不是Passenger）遇到了内部错误。

错误详情：

Your Ruby version is 2.3.1, but your Gemfile specified 2.5.1 (Bundler::RubyVersionMismatch)

The stdout/stderr output of the subprocess so far is:

然后我检查我安装的ruby版本。 ruby -v

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
rbenv 1.1.1-30-gc8ba27f
Rails 5.2.0

但/ var / lib / gems目录下没有任何gem文件夹2.5.1。只存在2.3.0文件夹。

甚至ruby版本2.5.1都没有出现在/ usr / lib / ruby /目录中。目前只有2.3.0。

编辑：我也尝试更改我的Gemfile中的ruby版本但是出错了。

Your Ruby version is 2.5.1, but your Gemfile specified 2.3.1

但是，当我使用rails s应用启动时启动我的应用。

Answer 1

尝试使用RVM（https://rvm.io/）并安装正确版本的ruby并设置默认值。

Answer 2

将Gemfile中的版本更改回2.5.1，然后运行bundle install。这应该更新您的Gemfile.lock，并在需要时重新安装或更新依赖项。

之后，尝试以乘客

开始

我相信名为2.3.0的文件夹是红鲱鱼。我注意到文件夹名称似乎与ruby版本不同步，所以我会忽略它。

如何解决您的Ruby版本是2.3.1，但您的Gemfile指定为2.5.1？
