Django makemessages，类型错误：预期的 str、字节或 os.PathLike 对象，而不是列表

Question

我正在尝试在 pycharm 中创建一个多语言 Django 项目。但一整天都在努力弄清楚为什么 makemessages 不生成 .po 文件。所以我寻求一些帮助。

设置.py

from pathlib import Path
import os
from decouple import config
from unipath import Path
from django.utils.translation import gettext_lazy as _
import environ

env = environ.Env()
environ.Env.read_env()


BASE_DIR = Path(__file__).resolve().parent.parent
CORE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale/'),
)
LANGUAGE_CODE = 'en-us'

LANGUAGES = [
    ('en', _('English')),
    ('fr', _('French')),
]

TIME_ZONE = 'UTC'

USE_I18N = True

USE_TZ = True

当我运行 python manage.py makemessages -l fr 时，我得到以下响应：

Answer 1

原因不是

LOCALE_PATHS

。 Django 会忽略

STATIC_ROOT

 ^[Django-doc] 和

MEDIA_ROOT

 ^[Django-doc]。确实：

def find_files(self, root):
    """
    Get all files in the given root. Also check that there is a matching
    locale dir for each file.
    """
    all_files = []
    ignored_roots = []
    if self.settings_available:
        ignored_roots = [
            os.path.normpath(p)
            for p in (settings.MEDIA_ROOT, settings.STATIC_ROOT)
            if p
        ]
    # …

这些显然是您的

settings.py

中的（非空）列表。

因此您应该重写这些设置，因此：

# settings.py

# …

STATIC_ROOT = [my_path]

应重写为：

# settings.py

# …

STATIC_ROOT = my_path

与

MEDIA_ROOT

相同。
