collectstatic 时 Django gettext 错误

Question

我正在尝试在我的 Ubuntu 服务器中运行以下命令:

./manage.py collectstatic -v 0 --noinput

我收到此错误消息:

struct.error: unpack requires a bytes object of length 4

它会是什么？该错误似乎无关紧要。

Answer 1

您似乎有一个空的 django.mo 文件(.mo 文件是那些包含翻译的文件)。考虑删除它，或重新创建它或重新安装 Django。

我想出来是因为:

1. 问题是由 gettext 提出的;
2. 在 parsing the header 时引发异常文件的；和
3. 异常是关于一个太短的字节串(可能是空的)。
