Windows 捆绑安装：必须设置 HOME 环境变量（或 HOMEDRIVE 和 HOMEPATH）并指向目录 (RuntimeError)

Question

我成功安装了捆绑器

gem install bundler

那我试着做

bundle install

我收到以下错误：

C:/Ruby22-x64/lib/ruby/site_ruby/2.2.0/rbreadline.rb:1097:in `<module:RbReadline>': HOME environment variable (or HOMEDRIVE and HOMEPATH) must be set and point to a directory (RuntimeError)

似乎是环境变量错误，但在我的系统中设置正确

set HOME
HOMEDRIVE=C:
HOMEPATH=\Users\My Näme

是的，我的名字中有斯堪的纳维亚字母，所以我想知道这是否是问题所在。我认为我以前在使用 web2py 安装程序时遇到过这种情况。

无论如何，有什么想法可以解决这个问题吗？

Answer 1

如果您在域 PC 上并且您的 PC 设置为活动目录的一部分，则您可能会遇到此问题。在这种情况下，您的HOMEPATH、HOMEDRIVE 和HOME 环境变量在您的企业活动目录或域中设置。一旦离开域组或与公司网络断开连接，您就会失去对这些变量的访问权限，因此会出现错误。使用setxin windows 永久环境变量覆盖企业环境变量并重新启动系统使其生效。

SETX HOMEDRIVE %SYSTEMDRIVE% -m
SETX HOMEPATH \Users\%username% -m
SET HOME=%SYSTEMDRIVE%\Users\%USERNAME%
SETX HOME "%HOME%"
SET TEMP=%HOME%\Local Settings\Temp
SETX TEMP "%TEMP%"
SETX TMP "%TEMP%"

这是在 Windows 10 上测试的，它可以工作。将其复制并粘贴到脚本中并放入您的启动文件夹或将其逐行粘贴到CMD 或PowerShell。或者，使用Task Scheduler 将其设置为任务。 注意 使用setx 时，使用双引号将带有空格的字符串包装起来。

Answer 2

运行Get-ChildItem Env: 它将返回您所有的环境变量。检查以确保 HOME 和 HOMEPATH 正确。

HOME -> C:\Users\Eric HOMEPATH -> \Users\Eric

您可以使用以下命令来修复： Remove-Variable -Force HOME Set-Variable HOME "C:\Users\(enter your username)"

Answer 3

我在执行“bundle exec jekyll s”时遇到了同样的错误，这太奇怪了，我以前从未遇到过错误。然后我尝试使用“gem install bundler”重新安装捆绑包。然后另一个警告显示：

ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_file_s_stat - C:/WINDOWS/system32/config/systemprofile

它给了我一个线索。我只是导航到目录并授予它所需的权限。那么问题就解决了。
这是多么美好的一天！
