I'm trying to run command " rake db:test:prepare" in 6.2 of Rails Tutorial book. 我正在尝试在Rails教程6.2中运行命令“ rake db:test:prepare”。 And then I had this problem
然后我有这个问题
I have already run " gem install bundler". 我已经运行了“ gem install bundler”。 But it wasn't work.

This usually comes up when the specified ruby version is not installed. 当未安装指定的ruby版本时,通常会出现这种情况。 To install using rvm run:
要使用rvm安装,请运行:
rvm install ruby-2.6.3
If you suspect it's already installed, then you may need to tell rvm to use the specific version, as it might default to another version (in this case 2.5.1). 如果您怀疑它已经安装,则可能需要告诉rvm使用特定版本,因为它可能默认为另一个版本(在本例中为2.5.1)。 To do that run:
为此,请执行以下操作:
rvm --default use ruby-2.6.3
If it's not installed, the above command will throw a relevant error. 如果未安装,则上述命令将引发相关错误。
