无效的规格缓存文件 [英] Invalid spec cache file

问题描述

我在安装了Windows 8的Gem 2.2.2上安装了ruby 2.0.0p247 [x64-mingw32]。我有一个永久性问题gem，使它几乎无法使用。每当我尝试安装一个新的gem时，我总会得到：

 错误：在执行gem时...无效的spec缓存文件在C：/ Users / ... 
  

过去，我已经能够运行 gem update 或 gem update --system ，这样就可以解决 one，single gem install 。随后的安装将会失败并出现相同的错误。

我试过删除 users /.../。gem 目录。当我这样做时， gem update 会重新创建该目录，并且会立即失败，并显示相同的错误消息。 $ b 安装ruby 1.9.8几次试图解决问题，然后升级到ruby 2.0.0。在所有重新安装和升级过程中，问题依然存在。

我在这里结束了智慧。谁能帮我解决这个问题？

希望这有助于。

I have ruby 2.0.0p247 [x64-mingw32] with Gem 2.2.2 installed on Windows 8. I have a persistent problem gem that is making it virtually unusable. Whenever I try to install a new gem, I invariably get:

ERROR: While executing gem ... Invalid spec cache file in C:/Users/...

In the past, I've been able to run gem update or gem update --system and that would clear up the problem for one, single gem install. Subsequent install would fail with the same error. Now even gem update fails with that error message.

I've tried deleting the users/.../.gem directory. When I do that, gem update recreates that directory and promptly fails with the same error message.

I re-installed ruby 1.9.8 with gems several times to try to cure the problem, then upgraded to ruby 2.0.0. Throughout all re-installs and upgrades, the problem persisted.

I'm at my wits end here. Can anyone help me resolve this issue?

Here's the backtrace on the edit"

解决方案

I had the same problem, but was able to fix it this way:

Delete the folder in users/%user%/.gem/ and rerun the command gem sources --update
