我尝试在我的机器上安装 Rails 6 rc1。然后我删除每个 Active* 或 Action* gem。我遇到了这个错误。

我试图做一个bundle update但无济于事。我正在使用 rbenv。

谁能给我指点？谢谢！

经过测试，我意识到这railties是罪魁祸首。

我也犯了以错误方式卸载rails的错误。请参考下面找到正确的卸载方法rails rc。

所以我只是重新安装rails来修复上面的错误。然后我再次卸载它。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
