在本地 GAE 服务器上运行烧瓶时出错 [Errno 13]答案

【问题标题】：Error running flask on local GAE server [Errno 13]在本地 GAE 服务器上运行烧瓶时出错 [Errno 13]
【发布时间】：2012-06-20 16:46:46
【问题描述】：

尝试在 Windows 上的 GAE 开发服务器上运行 Kamal Gill 的 flask-appengine-template。尝试获取页面时出现此错误。已经尝试重新安装 Python 和 App Engine。通过谷歌搜索找不到任何类似的问题。帮助我，StackOverflow，你是我唯一的机会。

标签： python google-app-engine flask

【解决方案1】：

有同样的问题。使用 64 位 python 修复它。

【讨论】：

【解决方案2】：

很高兴看到我没有疯。大约两周前，我在尝试使用完全相同的模板时遇到了同样的错误。最后，由于我刚开始使用 Python，我实际上又回到使用以下资源自己拼凑它，而不是使用预先构建的模板。您是否偶然在 virtualenv 中运行它？我还没有正式写出这一切，但是使用以下资源，我能够让 Flask、GAE 和 Eclipse/PyDev 在 Windows 上很好地运行。

2.6 说明 http://forum.codecall.net/topic/60323-python-on-google-app-engine-creating-blog-engine/

将 GAE 项目从 2.6 迁移到 2.7 http://blog.notdot.net/2011/10/Migrating-to-Python-2-7-part-1-Threadsafe

【讨论】：

另外... 在 Eclipse 中使用 GAE 制作 PyDev developers.google.com/appengine/articles/eclipse mkyong.com/google-app-engine/… * 设置环境时要记住的一件事是确保任何 Eclipse 路径都应该用引号括起来。例如。 “{project_loc}”而不是 {project_loc}
会看看，但它不仅仅是 Windows 的东西。在我拥有的另一台 Windows 机器上运行良好。
我一直在 Windows XP 上工作，一旦我将该项目带到 64 位 Windows 7 机器上，它似乎就失败了。

【解决方案3】：

我从未使用过 Kamal Gill 的 repo，但我通常使用 blossom's Flask GAE skeleton。它更容易使用。只需更改应用标识符，将您的 google 应用引擎指向 gae 文件夹即可。

【讨论】：

它基于 2.5 运行时并且不是线程安全的。我可能可以稍微修改一下，但它已经一年没有维护了，这有点令人沮丧。
要在 boot.py 中迁移到 2.7 运行时，我们不再使用 cgi 处理程序，最后一行是：app = recording.appstats_wsgi_middleware(app)，在 app.yaml 中我们指定 'script: boot.app' 而不是 'script: boot.py'，骨架将工作。希望有帮助
这里是 Flask 在 python 2.7 运行时的完整仓库。它已经是线程安全的github.com/femmerling/Flask-GAE-py27
