I am absolute beginner using google app engine with python 2.7. I was successful with creating helloworld app, but then any changes I do to the original app doesn't show in localhost:8080. Is there a way to reset/refresh the localhost. I tried to create new projects/directories with different content but my localhost constantly shows the old "Hello world!" I get the following in the log window:

WARNING 2012-05-13 20:54:25,536 rdbms_mysqldb.py:74] The rdbms API is not available because the MySQLdb library could not be loaded.
WARNING 2012-05-13 20:54:26,496 datastore_file_stub.py:518] Could not read datastore data from c:\users\tomek\appdata\local\temp\dev_appserver.datastore
WARNING 2012-05-13 20:54:26,555 dev_appserver.py:3401] Could not initialize images API; you are likely missing the Python "PIL" module. ImportError: No module named _imaging

Please help...

这些警告不应阻止您看到新的“内容”，它们只是意味着您缺少一些运行本地版本的 CloudSQL (MySQL) 和图像 API 所必需的库。

首先要做的是尝试清除浏览器缓存。您对 Hello World 应用程序进行了哪些更改？

在浏览器中按 CTRL-F5，同时在页面上。强制缓存刷新。

您可以尝试打开 DOM 阅读器（Mac：alt+command+i，Windows：shift+control+i）重新加载页面。这很奇怪，但它对我有用。
