同时使用两个 Ruby 版本？

Question

I don't seem to be able to consistently switch between Ruby versions using rvm. Having many gem issues--for example:

capybara-3.26.0 requires ruby version >= 2.4.0, which is incompatible with the current version, ruby 2.3.3p222
[10:27:12] (master)
// ruby -v
ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin17]
[10:27:13] (master)
// rvm list
   ruby-2.3.3 [ x86_64 ]
=* ruby-2.6.0 [ x86_64 ]
   ruby-2.6.1 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

I get alternating messages that I'm using one but need the other. I don't care which I use so long as it works.

Even after rvm uninstall 2.3.3 I still get that I'm using 2.3.3 when trying to run bundle

I too experienced many issues with rvm . I switched to asdf and haven't looked back. I use multiple versions of Ruby, Elixir, Python, Erlang, etc. and use different versions on multiple projects. The Ruby plugin for asdf is asdf-ruby
