在Windows 7 64位上运行gem install时出错 [英] Error running gem install on Windows 7 64 bit

问题描述

我刚刚使用rubyinstaller.org的安装程序安装了ruby 1.9.2-p136，现在我正在尝试安装rails。当我做gem install rails时，出现以下错误：

I just installed ruby 1.9.2-p136 using the installer from rubyinstaller.org and now I am trying to install rails. When I do "gem install rails" I get the following error:

C:\Users\Clayton.USA>gem install rails
ERROR:  While executing gem ... (Errno::EINVAL)
    Invalid argument - P:/

下面是我正在运行的ruby和gem版本：

Here are the ruby and gem versions I'm running:

C:\Users\Clayton.USA>ruby -v
ruby 1.9.2p136 (2010-12-25) [i386-mingw32]

C:\Users\Clayton.USA>gem -v
1.3.7

更新：在此找到解决方案：如何停止'宝石'实用工具访问我的主目录？

Update: found the solution here: How to stop the 'gem' utility from accessing my home directory?

将以下内容添加到我的bin / gem开头：

Added the following to the start of my bin/gem:

ENV['HOME'] = "D:/Ruby192"

推荐答案

在我的情况下，从命令提示符运行以下命令将homedrive修正为c：并修复了gem更新问题

SET HOMEDRIVE = c：

In my case running following command from command prompt fixed the homedrive to c: and fixed the gem update issue
SET HOMEDRIVE=c:

您的HOMEDRIVE设置为P :,在该命令之后，它将被设置为C：

，您可以通过编写

SET HOMEDRIVE

将其设置为C之前和之后进行测试：

your HOMEDRIVE was set to P:, after that command it will be set to C:
you can test by writing only
SET HOMEDRIVE
before and after setting it to C:
