问题描述
不知何故，我的红宝石被损坏了，当我这样做时
Somehow, my ruby gems got corrupted, and when I do
$ sudo gem update
我明白了:
ERROR: While executing gem ... (Gem::Exception)
Invalid spec cache file in /home/sawa/.gem/specs/api.rubygems.org%443/specs.4.8
我删除了 .gem，并重新安装了 Ruby，但问题仍然存在.我该如何修复它?
I removed .gem, and reinstalled Ruby, but the problem persists. How can I repair this?
推荐答案
首先我建议你保存你的宝石列表，以防万一:
First I suggest you save your gem list, just in case:
$ gem list > gems.txt
验证您使用的是您认为的 SPEC CACHE:
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
查看您是否有任何过时的来源:
To see if you have any outdated sources:
$ gem sources
如果你要小心，你可以一个一个删除源，然后重新添加.(见下面的代码)
If you want to be careful, you can remove sources one by one, then re-add. (See code below)
尝试原始的，虽然它可能会失败:
Try pristine, though it will likely fail:
$ gem pristine --all
严厉的做法是删除所有的宝石规格:
The harsh approach is to delete all the gem specs:
rm -rf /home/sawa/.gem/specs
核心方法是删除你写的已经尝试过的gem目录:
The nuclear approach is to delete the gem directory, which you write that you've already tried:
rm -rf /home/sawa/.gem
我的最佳猜测是您的一个 gem 源返回了一个不正确的文件，这可能是一个临时问题.您可以通过删除所有 gem 来源来解决这个问题.
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.
如果清除源不起作用，则可以删除所有并重新添加:
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...
