降级到Rails 5.1.0错误

Question

So I want to have my new rails project to be using gem rails 5.1.0 specifically, but each time I do create a "rails new project", by default it will be rails 5.2.0 in my gemfile. 所以我想让我的新rails项目专门使用gem rails 5.1.0，但是每次我创建“ rails new project”时，默认情况下，我的gemfile中将是rails 5.2.0。 So what I do is I will manually change it to rails 5.1.0 in my gemfile. 所以我要做的是在我的gemfile中手动将其更改为rails 5.1.0。 However, I will get this result each time i do a bundle exec rails c: 但是，每次执行bundle exec rails c时，我都会得到以下结果：

I am pretty new to rails so I dont know if there's something I missed out or something I do wrongly. 我是Rails的新手，所以我不知道是否错过了某些事情或做错了什么。 Hopefully someone could enlighten me on this. 希望有人能对此有所启发。

Thank you in advance. 先感谢您。

add gem 'rails', '~> 5.1' to gem file in your App 在您的应用程序中将gem 'rails', '~> 5.1'到gem文件

Try remove Gemfile.lock and re-do a bundle update eventmachine 尝试删除Gemfile.lock并重新执行捆绑更新事件机

Answer 2

I fixed my own issue. 我解决了自己的问题。

I ran a clean uninstallation of rails on my system using 我使用以下命令在系统上进行了Rails的干净卸载

gem uninstall rails
gem uninstall railties

And installed the gem I want again. 并再次安装了我想要的宝石。

Worked perfectly. 工作完美。

If you have multiple versions of rails installed in your system, you can specify which version of Rails to create a new app with by running: 如果您的系统中安装了多个版本的Rails，则可以通过运行以下命令指定用于创建新应用程序的Rails版本：

rails _version_ new APP_NAME

For example, if you want to use Rails 5.1.0 you'd run: 例如，如果要使用Rails 5.1.0，请运行：

rails _5.1.0_ new APP_NAME

and a new rails 5.1.0 application will be created for you. 然后将为您创建一个新的Rails 5.1.0应用程序。 Ensure you have the version of rails installed: 确保已安装Rails的版本：

gem list \^rails\$
