我正在尝试遵循 Google 应用引擎教程
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。任何想法为什么会发生这种情况？[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
