启动Rails服务器的问题

启动新项目的Rails服务器时遇到一些问题。我已经成功启动了同一文件夹中项目的Rails服务器。我在文件夹之外尝试了此操作，问题仍然存在。我已经更新了ruby，更新了RVM，更新了捆绑程序版本，但仍然无济于事。

这是我不断收到的错误：

在启动rails server时，我也遇到了同样的问题。因此，我安装了最新的msgpack宝石，这解决了我的问题。使用以下命令安装最新版本的gem msgpack 

gem install msgpack -v 1.3.1

答案 1 :(得分：0)

此问题的主要原因是不兼容的gem版本。当gem版本在两个不同的rails项目之间发生冲突时，会发生此问题。我建议您使用Ruby Version Manager rvm，该版本可用于为每个Rails项目创建虚拟环境。

如何避免这些问题：

  • 使用rvm gemset，可为您提供分隔的独立红宝石设置。

示例：

  • 安装rvm后，您可以使用命令rvm install ruby-2.6.3下载任何版本的ruby
  • 使用命令rvm use 2.6.3激活特定的红宝石版本。
  • 如果要在Rails中创建新项目，请说test_project，还要确保创建一个具有相同名称的gemset。例如：rvm gemset create test_project
  • 使用命令rvm use 2.6.3@test_project激活游戏集。
  • 完成上述所有步骤后，请按照通常用于安装gem的过程进行操作。例如：gem install bundler和bundle install

注意：

  • 在启动项目的Rails服务器之前，请确保激活gemset。例如：rvm use 2.6.3@test_project

希望这可以解决您的问题。
