致命devappserver2错误：Appengine 1.7.6和1.7.5 python 2.7中的PYTHON_EGG_CACHE，win7

我试图使用Appengine SDK版本1.7.6，但收到致命错误（如下所述），因此恢复到1.7.5，其中我的应用工作正常。然而，当我尝试在1.7.5中运行实验devappserver时，我在1.7.6中看到的错误再次出现。我在win 7机器上运行Python 2.7。标准安装AppEngine的选择。致命devappserver2错误：Appengine 1.7.6和1.7.5 python 2.7中的PYTHON_EGG_CACHE，win7

这些错误信息是指涉及到PYTHON_EGG_CACHE权限，但... - 2）的位置注明的应用程序可以成功地提取文件 - 1）他们不为“老” dev_appserver 发生。事实上，我将PYTHON_EGG_CACHE的路径更改为另一个位置，给了它开放的权限，但仍然收到错误。 - 3）我的网站包中有pyyaml，所以我不知道为什么它需要做临时提取。

寻求解决方案的任何帮助将不胜感激，因为我将被迫在几次发布时间使用新的devappserver。

我建议在相应的组中报告这个，以确保它看到：https：//groups.google.com/forum/？fromgroups＃！论坛/ appengine-devappserver2-discuss – dragonx 2013-03-25 06:51:12

谢谢。已经这样做了。 – BenHealey 2013-03-25 07:27:42

如果有人有相同的问题走来，为我工作的决议如下：

解压PyYAML-3.10-PY2。在您的python27网站包目录中的7-win32.egg到站点包内的新目录中。您需要将解压缩到像NEWPYYAML-3.10-py2.7-win32.egg 这样的目录名称中，以避免名称冲突。
重命名你的原蛋。到其他东西（例如，OLDPyYAML-3.10-py2.7-win32.egg）。
重新命名新的目录来PyYAML-3.10-py2.7-win32.egg

蛋现在实际上会指向在包含解压Python文件您的站点包目录中的所有引用。新的devappserver应该能够处理这个问题。

不确定如何解开Windows中的鸡蛋？看到这里（假设你有Winzip或类似的安装）： http://mail.python.org/pipermail/chicago/2007-July/002301.html
