未定义的方法`end_with？' for“no file to load - Win32API”：String（NoMethodError） [英] Undefined method `end_with?' for "no such file to load -- Win32API":String (NoMethodError)

问题描述

我只是建立了一个新的服务器，想安装Twitter gem，但是遇到了Ubuntu 8.04 / Ruby 1.8.6的问题。

multi_json需要RubyGems> = 1.3.6，但运行gem update --system显然会尝试并更新到RubyGems 1.5，这是Ruby 1.8.6无法完成的，并且会失败并显示以下错误：

 未定义的方法`end_with？'为没有要加载的文件 -  Win32API：String（NoMethodError）
 
 from ./lib/rubygems/config_file.rb:55 
 from ./lib/rubygems/custom_require.rb:29:in'gem_original_require'
 from ./lib/rubygems/custom_require.rb:29:in 'require'
 
 ... 
  

有什么想法？

谢谢

Steve

解决方案

升级文档提到您可以使用以下命令来降级宝石。只需说它可能适用于升级到特定版本：

gem update --system 1.3.7 例如（使用root / sudo）：



cd / usr / src&& wget http://production.cf.rubygems.org/rubygems/rubygems- 1.3.7.tgz

tar -xvf ruby​​gems-1.3.7.tgz

ruby​​ setup.rb

I'm just setting up a new server and want to install the Twitter gem but am running into problems on Ubuntu 8.04/Ruby 1.8.6

It says that "multi_json requires RubyGems >= 1.3.6", but running "gem update --system" obviously tries and updates to RubyGems 1.5 which can't be done on Ruby 1.8.6 and fails with the following error:

 undefined method `end_with?' for "no such file to load -- Win32API":String (NoMethodError)

 from ./lib/rubygems/config_file.rb:55
 from ./lib/rubygems/custom_require.rb:29:in 'gem_original_require'
 from ./lib/rubygems/custom_require.rb:29:in 'require'

 ...

Any ideas?

Thanks

Steve

解决方案

The upgrade documentation mentions that you can use the following command to downgrade the gems. Suffice to say that it probably works for upgrading to a specific version as well:

gem update --system 1.3.7

In the light of the comment I just received you could also try to install an older gem your self.

For example (using root / sudo):

cd /usr/src && wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz

tar -xvf rubygems-1.3.7.tgz

ruby setup.rb
