Question

我正在尝试将旧项目更新为新的Rails版本，当我尝试在本地以调试方式运行它时出现此错误

正如您在上面看到的，我正在使用Windows。该项目现在具有ruby版本ruby-2.4.4-p296

我试图重新安装gem并运行bundle install / update，但是它不起作用...

感谢您的帮助。预先感谢

以退出代码0结束的过程

我认为问题是gem'pg'的版本，但是我不知道应该放哪个版本

Answer 1

pg-0.20.0与较新的RubyInstaller版本不兼容。您必须至少更新到pg-0.21.0。最好删除Gemfile中pg的版本要求，以便将其更新为bundler update上的最新兼容版本。另请参见pg changelog。

尝试加载gem'pg'
