我正在尝试在我的Mac Sierra机器上安装Ruby 2.4。 我以为我已经成功地做到了...
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

Warning, new version of rvm available '1.28.0', you are using older version '1.26.11'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc
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红宝石版本...
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，导航到我的项目目录时，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？
更改默认红宝石：
$ 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
在项目中
- 不要在 Gemfile 中添加任何"红宝石"2.4.0"行
- 如果有.rvmrc文件，请将其删除
- 创建文件（至少某些 RVM 版本要求同时存在版本和 Gemset 文件）
.红宝石版本
2.4.0
.红宝石宝石
app
触发 rvm 以重新加载它们
cd .
ruby --version
rvm gemset list
- 安装 2.4.0 的捆绑程序（如果缺少）
rvm 2.4.0@global do gem install bundler
