Question

我安装了安装了setuptools的Windows 7和Python 2.7。

下载pitz模块（easy_install pitz）后，Google App Engine停止工作：

bad runtime process port ['']

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] : 'C:\\Users\\Kostr\\AppData\\Roaming\\Python-Eggs\\pyyaml-3.11-py2.7-win-amd64.egg-tmp\\_yaml.pyd'

The Python egg cache directory is currently set to:

  C:\Users\Kostr\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.

如何解决这个问题？

Answer 1

来自：https://code.google.com/p/modwsgi/wiki/ApplicationIssues

要避免此特定问题，可以在WSGI应用程序脚本文件的开头设置PYTHON_EGG_CACHE缓存环境变量。环境变量应设置为Apache运行的用户拥有和/或写入的目录。

import os
os.environ['PYTHON_EGG_CACHE'] = '/usr/local/pylons/python-eggs'

再次确保存在。对于Windows用户，可能是：

os.environ['PYTHON_EGG_CACHE'] = '/tmp'

或者，如果使用mod_wsgi 2.0，也可以使用WSGIPythonEggs指令用于在嵌入模式下运行的应用程序，或者在使用守护进程模式时使用WSGIDaemonProcess指令的python-eggs选项。

请注意，您应该避免使用任何可写入任何人的目录或文件，因为这可能会危及安全性。另请注意，如果在同一个Web服务器下托管多个应用程序，它们将作为同一个用户运行，因此每个人都可以查看和修改其他文件。如果这是一个问题，您应该将应用程序托管在作为不同用户或不同系统运行的不同Web服务器上。或者，应用程序所需或更新的任何数据都应托管在一个数据库中，每个应用程序都有单独的帐户。

Answer 2

听起来你没有权限写入目录。卸载pitz，然后使用-Z标签重新安装以将其安装为解压缩版本。然后，您不需要每次都提取缓存目录。这应该解决目录/权限问题。
