Question

我尝试在计算机上安装Rails 6 rc1。然后，我删除每个Active *或Action *宝石。而且我遇到了这个错误。

我尝试做一个bundle update，但无济于事。我正在使用rbenv。

有人可以给我指点吗？谢谢！

在测试之后，我意识到railties是主要的罪魁祸首。

我也错误地以错误的方式卸载了rails。请参考以下内容，找到卸载rails rc的正确方法。

因此，我只需重新安装滑轨即可解决以上错误。然后，我再次将其卸载。然后我卸载railties

gem install rails --pre
gem uninstall rails -v 6.0.0.rc1
gem uninstall railsties -v 6.0.0.rc1

如何修复无法找到'activesupport'（= 6.0.0.rc1）-确实找到了：[activesupport-5.2.3]（Gem :: MissingSpecVersionError）
