Question

當我嘗試通過RVM更新版本的紅寶石：rvm install ruby-2.4.0

我有這樣的錯誤

No fallback URL could be found, try increasing timeout with:

There has been an error fetching the ruby interpreter. Halting the installation. 

有人知道如何解決它？因爲這引發一些麻煩和Rails 5，我得到這個消息：/config/initializers/new_framework_defaults.rb:15:in '<top (required)>: undefined_method 'to_time_preserves_timezone='

這是我new_framework_defaults.rb

# Make Ruby 2.4 preserve the timezone of the receiver when calling `to_time`.                      
# Previous versions had false. 
ActiveSupport.to_time_preserves_timezone = true 

Answer 1

目前，只有預覽。運行此命令：

rvm install 2.4.0-preview1 

Answer 2

第一：

echo "export rvm_max_time_flag=20" >> ~/.rvmrc 

後：

rvm install 2.4.0 

實施例：

[root@localhost ~]# rvm install 2.4.0
