django-admin.py makemessages 失败

Question

我之前用 django-admin.py makemessages -a 创建了语言文件。

但是过了一段时间后，我尝试创建 *.po 文件时都失败了，出现了以下错误：

django-admin.py makemessages  -v 3 -a
examining files with the extensions: .html and .txt
Traceback (most recent call last):

我试过用不同的文件扩展名和忽略模式。你们有什么建议吗？

Answer 1

这个命令对我来说是有效的：

python manage.py makemessages --locale=en --ignore=venv/*

Answer 2

我从django 1.7开始就遇到了同样的问题。我使用manage.py来生成消息，而不是使用django-admin.py，并且不包括环境文件夹：

python manage.py makemessages --locale=en --ignore=venv/*

Answer 3

这是因为在Django 1.7.1版本中出现了一个bug。你可以通过更新Django到最新版本来解决这个问题，方法是使用：

  pip install -U django
