'_getfullpathname: path should be string, bytes or os.PathLike, not tuple' 上传文件接口调试的时候总报这个错误

经过调试，发现setting里设置的media_root自作主张跟static一样加了一个逗号，导致路径变成元组，所以报错，删掉逗号就好了

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    BASE_DIR / 'mytest/dist/static',
)
MEDIA_URL = '/media/'
MEDIA_ROOT = (BASE_DIR / 'mytest/dist/files')
