无法执行 makemessages 命令

Question

我想使用 i18n，并在我的settings.py 中创建了一个语言环境目录和其他设置。

然后我在我的 PyCharm 中执行python manage.py makemessages -l zh-cn 命令，但失败了。

我的回溯如下：

Traceback (most recent call last):

Answer 1

这是因为你的locale目录下有__init__.py和__init__.pyc文件，你应该删除它们。

右键locale目录->在Finder中显示->就可以看到了，如果只在Pycharm中显示，是看不到.pyc文件的。
