我是RabbitMQ的初学者，我有一些问题要启用管理插件。该兔子服务器启动并运行，但是当我尝试启用该插件，我得到这在Windows命令提示符下：

尝试使用rabbitmq-plugins.bat列表列出插件时，我得到相同的错误。
它正在三台完全不同的机器上运行Windows 7(两个)和Windows Servver 2008 R2(一个)。
另外，我使用的是rabbitmq-server-3.1.5和Erlang R16B01。
就这样，它显示为一个答案：从
this link在OP的评论。
The problem was that %HOMEDRIVE% was pointing to U: instead of C:
要解决并安装管理插件，只需重新命名HOMEDRIVE。
SET HOMEDRIVE=C: rabbitmq-plugins.bat enable rabbitmq_management rabbitmq-service.bat stop rabbitmq-service.bat install rabbitmq-service.bat start
