使用VSonline部署到Azure遇到了没有安装sdk2.4的问题

今天我使用VSonline部署云服务时遇到了问题
TFS提示了Failed to locate the Microsoft Azure SDK. Please make sure the Microsoft Azure SDK v2.4 is installed.

昨天我升级了Azure的sdk到2.4,然后发布到Azure,当时成功了
今天当我再次发布到Azure的是否出现了以上的错误
我尝试了很多方法,包括使用之前成功发布过的版本发布也会遇到以上的问题
不知道是否需要把SDK降回2.3?

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\Windows Azure Tools\2.4
是否存在,建议先再次安装下azure sdk看看
