不能在任何的在你的Gemfile中列出的寶石來源找到寶石

Question

jonsdirewolf:~/workspace $ bundle install 
Could not find gem 'roo (~> 2.7.0)' in any of the gem sources listed in your Gemfile. 
Run `bundle install` to install missing gems. 

我的Gemfile：

source "http://rubygems.org" 
ruby "2.4.0" 
# gem "rails" 
gem "mysql2" 
gem "activerecord" 
gem 'byebug' 
gem 'write_xlsx' 
gem 'mechanize' 
gem 'pry' 
gem 'pry-byebug' 
gem "roo", "~> 2.7.0" 

我該怎麼辦？

Answer 1

rubygems.org力量HTTPS：

> curl -I http://rubygems.org 
HTTP/1.1 301 Moved Permanently 
Content-Type: text/html 
Location: https://rubygems.org/ 

，我的直覺是，捆綁可能不遵循重定向。

所以解決將是使用

source "https://rubygems.org" 

以 「https」 而不是 「HTTP」。
