【中文标题】现有 Django 项目中的语法错误【英文标题】:Syntax error in existing Django project 【发布时间】:2018-04-22 07:51:15 【问题描述】:我第一次安装了现有的 Django 项目,但在启动服务器时遇到了问题python manage.py runserver
这就是我所做的
1.克隆repo,
2.制作虚拟环境
3.Pip install requirements.txt
4.生成访问令牌和密钥并放入secrets.sh。我在settings.py
和secrets.sh
中有相同的 SECRET_KEY,并且我已将 secrets.sh 添加到.gitignore
5.更改settings.py
如下:
DATABASES =
'default':
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
'USER': 'name',
'PASSWORD': '',
'HOST': 'localhost',
'PORT': '',
我无法运行python manage.py migrate
结果如下:
(tag_gen) local_user@local_user:~/Repo/tag_gen/generator$ python manage.py runserver
Performing system checks...

想法?
【问题讨论】:
使用 sqlite3 时,您可以废弃DATABASES['default']
但 ENGINE
和 NAME
中的所有字段。
【参考方案1】:
1.检查你拥有的python和django版本应该与安装的要求兼容。 如果你的 python 版本超过 3.+ 运行服务器
python3 manage.py runserver
如果是 python 版本 2.7+,则为 else
python manage.py runserver
【讨论】:
【参考方案2】:您尝试运行的项目使用 Python ≥ 3.5,但您尝试在 2.7 中运行它。
语法(request: WSGIRequest):
是一个类型提示。它是由a few years ago 引入的,但仅添加到较新版本的 Python 3 中。没有努力支持 Python ≤ 3.4。
您需要查找有关如何使用足够高版本的 Python 创建virtualenv
的说明。此更改基于操作系统,因此详细说明可能超出此问题的范围,but there is plenty of advice on the topic already。
【讨论】:
是的,你是对的。我准备了新的 venv 和作品。谢谢。以上是关于现有 Django 项目中的语法错误的主要内容,如果未能解决你的问题,请参考以下文章
