RoR Rake - 有关 gem 的数据库错误
我正在尝试使用此命令在我的 ror 应用程序中创建一个数据库：
rake db:create
并且收到此错误：
Could not find tzinfo-0.3.26 in any of the sources
但是当我执行“gem list”命令时，结果发现我有此 gem 的较新版本：tzinfo (0.3.27)
我可以做什么来同步我的宝石以使其更加兼容？这是一个常见问题吗？仅供参考，我正在使用 RVm 来管理我的宝石。
我确实执行了 rvm install tzinfo-0.3.26 命令并得到了此输出

I am trying to create a db in my ror application with this command:
rake db:create
and I got this error:
Could not find tzinfo-0.3.26 in any of the sources
But when I did the "gem list" command, it turned out I had a newer version of this gem: tzinfo (0.3.27)
What can I do to sync up my gems to be more compatible? Is this a common problem? FYI I am using RVm to manage my gems.
I did do an rvm install tzinfo-0.3.26 command and got this output

如果这就是您输入并执行的内容。应该尝试运行
来安装 tzinfo 的 0.3.26 版本，
您首先执行的操作会告诉 rvm 安装 ruby 运行时，而不是 gem。
if thats what you typed in and executed. Should try running
that would install the 0.3.26 version of tzinfo
what you did first tells rvm to install a ruby runtime, not a gem.
我的猜测是您在应用程序中明确要求 0.3.26。您可以将要求更改为“~>0.3.26”或使用“gem install tzinfo -v 0.3.26”安装所需的版本。
My guess would be that you're explicitly requiring 0.3.26 in your application. You could either change the requirement to "~>0.3.26" or install the required version with "gem install tzinfo -v 0.3.26".
