损坏的红宝石宝石系统 [英] Corrupted ruby gem system

问题描述

不知何故，我的宝石宝石已损坏，当我做的时候

  $ sudo gem update 
  

我得到：

 错误：执行gem时（Gem :: Exception）
 /home/sawa/.gem/specs/api.rubygems.org%443/specs.4.8中的spec缓存文件无效
  

我删除了 .gem ，并重新安装了Ruby ，但问题仍然存在。如何修复此问题？

解决方案

首先，我建议您保存您的宝石列表，以防万一：

  $ gem list> gems.txt 
  

验证您是否使用SPEC CACHE，您认为自己是： p>

  $ gem env | grepSPEC CACHE
  -  SPEC CACHE DIRECTORY：/home/sawa/.gem/specs 
  

<

  $ gem来源
  
 / pre> 
 
 
如果您想要小心，可以逐个删除源代码，然后重新添加。 （请参阅下面的代码）
 
 
 
尽量保持原始状态，但可能会失败： 
 
 
  $ gem pristine --all 
  
严酷的方法是删除所有gem规格：
  rm -rf /home/sawa/.gem/specs 
  
 
 
核方法是删除您已经尝试过的gem目录： 
 
 
  rm -rf /home/sawa/.gem 
  
我最好的猜测是你的一个宝石来源正在返回一个不正确的文件，可能是一个暂时的问题。您可以通过移除您所有的宝石来源来解决这个问题。
  $ gem sources  -  -clear-all＃清除缓存，但不会删除源
 $ gem sources --update＃可能会起作用，在这种情况下，您现在可以停止。 
  
如果清除源代码不起作用，那么您可以删除所有代码并重新添加：
  $宝石来源
 $宝石来源--remove http://gems.rubyforge.org/ 
 $宝石来源--remove http://gems.github.com 
 ...等... 
 $宝石来源 -   - 更新＃应该工作正常，因为没有来源
 $ gem sources --add http://gems.rubyforge.org/ 
 $ gem sources --update 
 $ gem sources --add http://gems.github.com 
 $宝石来源 - 更新
 ...等... 
  
 
Somehow, my ruby gems got corrupted, and when I do
$ sudo gem update
I get:
ERROR:  While executing gem ... (Gem::Exception)
    Invalid spec cache file in /home/sawa/.gem/specs/api.rubygems.org%443/specs.4.8
I removed .gem, and reinstalled Ruby, but the problem persists. How can I repair this?
解决方案
First I suggest you save your gem list, just in case:
$ gem list > gems.txt
To verify that you're using the SPEC CACHE that you think you are:
$ gem env | grep "SPEC CACHE"
 - SPEC CACHE DIRECTORY: /home/sawa/.gem/specs
To see if you have any outdated sources:
$ gem sources
If you want to be careful, you can remove sources one by one, then re-add. (See code below)


Try pristine, though it will likely fail:
$ gem pristine --all
The harsh approach is to delete all the gem specs:
rm -rf /home/sawa/.gem/specs
The nuclear approach is to delete the gem directory, which you write that you've already tried:
rm -rf /home/sawa/.gem
My best guess is that one of your gem sources is returning an incorrect file, possibly a temporary problem. You can figure this out by removing all your gem sources.
$ gem sources -​-clear-all # clears the cache, but doesn't remove the source
$ gem sources --update  # probably will work, in which case you can stop now.
If clearing the sources doesn't work, then you can remove all and re-add:
$ gem sources 
$ gem sources --remove http://gems.rubyforge.org/
$ gem sources --remove http://gems.github.com
...etc ...
$ gem sources -​-update  # should work fine, because there are no sources
$ gem sources --add http://gems.rubyforge.org/
$ gem sources --update
$ gem sources --add http://gems.github.com
$ gem sources --update
...etc...
