Question

我尝试使用Appengine SDK 1.7.6版，但收到致命错误（如下所述），所以恢复到1.7.5，我的应用程序运行正常。但是，当我尝试在1.7.5中运行实验性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。 AppEngine的标准安装选择。

这些错误消息是指与PYTHON_EGG_CACHE相关的权限，但是...... - 1）'old'dev_appserver不会出现它们 - 2）应用程序可以成功地将文件提取到指出的位置。实际上，我将PYTHON_EGG_CACHE的路径更改为另一个位置，赋予它全开权限，但仍然收到错误。 - 3）我的网站包里有pyyaml，所以不知道为什么它还需要做一个临时提取。

任何寻求解决方案的帮助都会受到赞赏，因为我将被迫在几个发布时间内使用新的devappserver。

pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Error 5] Access is denied: 'C:\\Users\\Ben\\AppData\\Roaming\\Python-Eggs\\py
yaml-3.10-py2.7-win32.egg-tmp\\_yaml.pyd'

The Python egg cache directory is currently set to:

  C:\Users\Ben\AppData\Roaming\Python-Eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

如果有人出现同样的问题，那对我有用的解决方案如下：

在python27站点包中解压缩PyYAML-3.10-py2.7-win32.egg 目录到site-packages中的新目录。你需要将其解压缩到目录名称，如NEWPyYAML-3.10-py2.7-win32.egg 避免名称冲突。
重命名原来的鸡蛋。到其他东西（例如，OLDPyYAML-3.10-py2.7-win32.egg）。
将您的新目录重命名为PyYAML-3.10-py2.7-win32.egg

对egg的所有引用现在实际上都指向包含解压缩的python文件的site-packages中的目录。新的devappserver应该能够解决这个问题。
