Question

与团队一起处理一个相当大/复杂的Django项目时，我们偶尔会看到ValueError: embedded null byte的runserver崩溃。我们重新启动runserver，它很好 - 无论是几分钟还是几天。我们可以检测到没有导致崩溃的模式（似乎完全随机）。幸运的是，它只发生在本地开发中，而不是发生在我们的服务器上，但我担心它会让我们陷入困境。

下面的堆栈跟踪并未指向我们代码中的任何位置 - 似乎来自Django或virtualenv本身。

在El Capitan上使用Django 1.9.8，Python 3.5.0。

我看不到任何调试方法。理论？

ValueError: embedded null byte

其中一个=if(A2="L", if(now()-B2>=84, "Need to reach out!", if(now()-b2>=70, "Schedule a call!", if(now()-B2<56, "Communications up to date", "" ) ) ), if(A2="M", if(now()-b2>=42, "Need to reach out!", if(now()-b2>=28, "Schedule a call!", "Communications up to date" ) ), if(A2="H", if(now()-b2>=21, "Need to reach out!", if(now()-b2>=14, "Schedule a call!", "Communications up to date" ) ) ) ) )& if(C2="scheduled", " - Communication Scheduled", "" )对象的AppConfig属性中包含空字节。
其中一个path有空字节。
其中一个文件采用“错误”编码，因此Django会将某些内容视为空字节（例如LOCALE_PATHS）。
项目目录中的一个文件或目录名称中包含空字节（AppConfig.path）。
其他原因。

autoreload.py lines与此问题有关。 \x00如果其参数为空字节，则引发os.path.isdir()，e。 G。 ValueError: embedded null byte。

您可以尝试修改os.path.isdir('foo\x00bar')，暂时注释掉这些行：

autoreload.py

并添加：

basedirs = [os.path.abspath(basedir) for basedir in basedirs
            if os.path.isdir(basedir)]

神秘的“嵌入空字节”错误
