GoogleAppEngineLauncher：數據庫磁盤映像格式不正確

Question

我寫的谷歌應用程序引擎我想運行我的應用程序，每次一個小應用程序，我有以下錯誤：

*** Running dev_appserver with the following flags: 
    --skip_sdk_update_check=yes --port=13080 --admin_port=8005 --clear_datastore=yes

當我運行的其他應用我已經創建，我沒有任何錯誤。 我嘗試了一些基本思路：

• 刪除/重新添加該應用

• 刪除應用程序啓動器，然後重新安裝

• 重新啓動Mac

• 定位數據庫，其中可能是一些grep的

沒有工作。任何想法？

Answer 1

默認的日誌數據庫文件名是log.db。它存儲在您的應用程序存儲目錄，默認情況下位於您tempfile.gettempdir()目錄，命名爲appengine.[appname].[userid]。

的appname部分均採用值從app.yaml（尋找application條目），取代:冒號用下劃線，最後~波浪之前刪除一切（如果有的話）。

所以，如果您的應用程序被稱爲foobar和您的用戶名是jbj，損壞的SQLite數據庫位於：

`python -c 'import tempfile;print tempfile.gettempdir()'`/appengine.foobar.jbj/log.db 

在Mac OS X，tempfile.gettempdir()返回/var/folders某處下散列路徑;它只是從TMPDIR環境變量中獲取，所以你應該只是能夠使用：

rm $TMPDIR/appengine.foobar.jbj/log.db 

您可以安全地刪除此文件，它會被重新創建下次啓動應用程序的時間。
