我刚刚在我的开发机器上从Python 2.6.1升级到2.6.4,并在启动python脚本时显示以下消息:
无法将文件提取到egg缓存中
尝试将文件提取到Python egg缓存时发生以下错误:
[Errno 13]权限被拒绝:'/ var/www/.python-eggs'
Python egg缓存目录当前设置为:
/var/www/.python-eggs
也许您的帐户没有对此目录的写入权限？您可以通过将PYTHON_EGG_CACHE环境变量设置为指向可访问的目录来更改缓存目录.
python文档中没有任何内容,所以我对于放置此目录及其用途的最佳实践有点不知所措.
有人可以解释一下Python egg缓存是什么吗？
另外,你能解释为什么/如何与site-packagesPython用来存储鸡蛋的目录不同(据我所知)？
我正在服务器上部署我的django应用程序,在最后阶段我收到此错误:
ExtractionError at /admin/
Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the Python egg
cache:
[Errno 13] Permission denied: '/.python-eggs'
The Python egg cache directory is currently set to:
/.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.
Request Method: GET
Request URL: http://go-ban.org/admin/
Exception Type: ExtractionError
Exception Value:
Can't …我们一直在使用Trac进行任务/缺陷跟踪,事情进展顺利,但今天早上它开始提供500错误.查看Apache error_log,我得到一个最终的堆栈跟踪:
PythonHandler trac.web.modpython_frontend: ExtractionError: Can't extract file(s) to egg cache The following error occurred while trying to extract file(s) to the Python egg cache: [Errno 13] Permission denied: '/.python-eggs' The Python egg cache directory is currently set to: /.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
所以我明确地将PYTHON_EGG_CACHE设置为/ srv/trac/plugin-cache.我重新启动了Apache.然而我得到了同样的错误(它仍然说"鸡蛋缓存目录当前设置为:\n \n /.python_eggs.")
我该怎么办？重新安装Trac最简单的事情是什么？如果我走这条路,我需要采取哪些措施来确保我不会丢失现有数据？
