我有一个处理apache2的应用程序。我希望切换到uwsgi。 在部署之后，我遇到了类似随机错误的奇特问题：

django在邮件上发送了类似的例外情况：没有模块名称视图 - 这当然不是真的，因为这个应用程序在apache工作了两年以来：）
我不知道问题出在哪里 - 我知道我无法在我的舞台环境中重现它 - 这是一台克隆生产机器。据我所知，它不是代码依赖错误或应用程序问题。
在procution我正在使用当前配置：
我正在使用： django 1.3.1 uWSGI 1.1 nginx 1.0.12-1~dotdeb.0 python 2.6 debian 6.0.3 2 x QC Xeon E5540，8 gb ram

如果有人遇到相同或类似的问题，我想问你社区。也许有人解决了，并希望分享如何？

答案 0 :(得分：1)
除非你看到其他错误，否则你应该尝试理解你所得到的错误，因为它最有可能是错误的原因。
在你的情况下，你错过了一个templatetags库（名为sso_token）。很可能这意味着您无法在生产计算机上安装依赖项，或者生产和开发之间的INSTALLED_APPS不同，以及您缺少提供该库的应用程序。
这种情况不太可能是由您的部署引起的，而且更可能是由您的生产环境和开发环境之间的不连续性引起的。
