【问题描述】：

我用django-admin.py makemessages -a创建了语言文件

稍后进行一点开发，所有创建 *.po 文件的尝试都失败了：

django-admin.py makemessages  -v 3 -a
examining files with the extensions: .html and .txt
Traceback (most recent call last):
  File "/usr/local/bin/django-admin.py", line 5, in <module>

我尝试了几个文件扩展名和 -ignore 模式。你有什么提示吗？

【问题讨论】：

您是否检查过以确保settings.MEDIA_ROOT 和settings.STATIC_ROOT 存在且有效？
我尝试将它们设置为：STATIC_ROOT = ( os.path.join(BASE_DIR, 'static'), ) 或使用 '/var/www/projectroot/static'
好吧，这很奇怪：我使用 vagrant 进行开发，并且所描述的错误在那里发生，而其他所有命令都不会产生失败。我已经在主机上试过了，一切正常。
那不是重复的，是同一个问题！

【解决方案1】：

自 django 1.7 以来我遇到了同样的问题。我使用 manage.py 来制作消息，而不是 django-admin.py，不包括环境文件夹：

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

【解决方案2】：

这是由于 Django 1.7.1 中引入的bug。您可以使用以下方法将 Django 更新到最新版本来解决此问题：

  pip install -U django
