昨天下午运作良好，但现在不行。
我使用goapp deploy MY_DIR/app.yaml进行部署，这是部署
02:38 PM Host: appengine.google.com 02:38 PM Application: MY_APP; module: MY_MOD; version: MY_VER 02:38 PM Starting update of app: exp-lkl, module: MY_MOD, version: MY_VER 02:38 PM Getting current resource limits. 02:38 PM Scanning files on local disk. 02:38 PM Scanned 500 files. 02:38 PM Scanned 1000 files. 02:38 PM Cloning 1085 application files. 02:38 PM Compilation starting. 02:38 PM Compilation: 1081 files left. 02:38 PM Compilation completed. 02:38 PM Starting deployment. 02:38 PM Checking if deployment succeeded. 02:38 PM Will check again in 1 seconds. 02:38 PM Checking if deployment succeeded. 02:38 PM Will check again in 2 seconds. 02:38 PM Checking if deployment succeeded. 02:38 PM Will check again in 4 seconds. 02:38 PM Checking if deployment succeeded. 02:38 PM Will check again in 8 seconds. 02:38 PM Checking if deployment succeeded. 02:38 PM Will check again in 16 seconds. 02:38 PM Checking if deployment succeeded. 02:39 PM Deployment successful. 02:39 PM Checking if updated app version is serving. 02:39 PM Rolling back the update. Error 500: --- begin server output ---Server Error

我也试过了：
1 /将sdk更新为最新版本
2 /更新版本（我试过go1.6和go1.8）
3 /使用appcfg.py
但是我得到了同样的错误
有人可以帮忙吗？
答案 0 :(得分：2)
最后我解决了这个问题。
应用程序引擎似乎更改了无可构建代码的错误消息。我的项目没有构建，app引擎显示之前没有可构建代码的路径，但现在app引擎返回500错误
Error 500:
--- begin server output ---
<h3>Server Error</h3><p>A server error has occurred.</p>
--- end server output ---
