Question

我正在尝试关注Google应用引擎tutorial

此代码在我的本地开发服务器上运行。当我执行：

 appcfg.py upload_data --config_file bulkloader.yaml --url=http://localhost:8888/remote_api --filename places.csv --kind=Place -e nobody@nowhere.com

我得到一个UnknownJavaServerError。任何想法为什么会这样？ [我的操作系统是Windows，python版本是2.7]

这是我得到的完整输出：

    C:\EclipseWorkspace\Android\MobileAssistant2-AppEngine\src>appcfg.py upload_data --config_file=bulkloader.yaml --filename=places.csv --kind=Place --url=http://localhost:8888/remote_api -e nobody@nowhere.com

Google_appengine 1.8.2和1.8.3中有bug。降级到1.8.1版以解决该问题。检查Windows 8 x64和Python 2.7.5 x64

尝试将数据上传到Google应用引擎数据存储时出现UnknownJavaServerError
