我可以看到vstf_testagent文件在构建过程中出现在我的Temp文件夹中，但我很困惑为什么它会抱怨安装路径。
以下是更多信息
答案 0 :(得分：2)
测试代理位置：
可选。测试代理（vstf_testagent.exe）的路径，如果不同于 默认路径。
如果您使用本地计算机或网络上的测试代理的副本，请指定该实例的路径。
该位置必须可由构建代理（使用其运行的标识）或测试代理（使用 上面配置的身份）。
根据Unable to find TestAgent installation path错误。您可以先手动下载代理，而不是从Internet下载代理。然后将VS 201x测试代理放在共享文件夹中，并让VS Test Agent Deployment任务部署它。 （不要在本地安装代理）
此外，如果您使用的是测试代理2017.您需要将TFS2017更新到TFS2017 update1。有一个＆＃34; 版本＆＃34;在每个任务的右上角下拉。您需要使用＆＃34;版本2＆＃34; VS Test Agent部署任务，以便您可以正确配置它以部署VS 2017测试代理。
