ruby-on-rails - 使用 rbenv 和 rails 5.2 修复“您的 Ruby 版本是 2.4.4，但您的 Gemfile 指定 2.5.1”错误

问题描述

我知道各种 ruby​​ 版本对此有很多问题。我相信我已经用尽了所有正常的修复（通常有效）。

这是一个一直在工作的应用程序，在我现在几个月（以及其他人之前几年）的相同环境中。它以前曾与 ruby​​ 2.4.4 和 ruby​​ 2.5.1 一起使用（使用 rbenv 切换）。

我想要 ruby​​ 2.5.1 并且 bundler 抱怨我的 ruby​​ 版本是 2.4.4

$ bundle exec rspec
Your Ruby version is 2.4.4, but your Gemfile specified 2.5.1

$ rbenv exec bundle exec rspec
Your Ruby version is 2.4.4, but your Gemfile specified 2.5.1

注意：rspec是示例，但它发生在任何前面的命令bundle exec

我检查了所有我知道的地方，以及互联网建议我应该查看的所有地方，但找不到将 ruby​​ 设置为 2.4.4 的内容（请参阅下面的详细信息）。

所以真正的问题是——下一个地方在哪里寻找错误配置的文件，rbenv或者bundler两者都有？

所有这些都给了我正确的 ruby​​ 版本

解决方案

ruby -v您是否从项目目录中执行命令？此外，如果您安装了新的 Ruby 版本，您也应该更新您的捆绑器。gem install bundler或者gem update bundler会为你做这件事。
