我正在尝试在我的Mac Sierra机器上安装Ruby 2.4。我以为我成功地做到了......
localhost:myproject nataliab$ rvm use 2.4.0
Warning! PATH is not properly set up, '/Users/nataliab/.rvm/gems/ruby-2.3.0/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.3.0'.
ruby-2.4.0 is not installed.
To install do: 'rvm install ruby-2.4.0'
localhost:myproject nataliab$ rvm install ruby-2.4.0

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.12/x86_64/ruby-2.4.0.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Updating certificates in '/usr/local/etc/openssl/cert.pem'.
Requirements installation successful.
Warning: DYLD_LIBRARY_PATH environment variable is set, this might interact with the compilation and ruby.

然后我看到了正确的Ruby版本......
localhost:myproject nataliab$ ruby -v
ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-darwin16]
但是当我打开一个新的终端窗口时，导航到我的项目目录，我不再看到新安装的版本......
localhost:myproject nataliab$ ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin16]
如何让我的版本坚持下去？

更改默认 ruby ：
$ rvm default ruby-2.4.0
$ rvm list
#rvm rubies
# ruby-2.3.0 [ x86_64 ]
#=* ruby-2.4.0 [ x86_64 ]
# ruby-head [ x86_64 ]
## => - current
## =* - current && default
## * - default
