Question

我第一次安装了现有的Django项目，我遇到了启动服务器的问题python manage.py runserver

这就是我所做的

1.克隆回购，

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中使用了相同的SECRET_KEY，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': '',
    }
}

我无法在下面运行python manage.py migrate结果：

(tag_gen) local_user@local_user:~/Repo/tag_gen/generator$ python manage.py runserver

想法？

Answer 1

您尝试运行的项目是使用Python≥3.5，但您尝试在2.7中运行它。

语法(request: WSGIRequest):是类型提示。它被引入a few years ago，但只被添加到较新版本的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的Python版本创建virtualenv的说明。这会根据操作系统而变化，因此详细说明可能超出了此问题的范围but there is plenty of advice on the topic already。

Answer 2

1。检查您拥有的python和django版本应与安装的要求兼容。如果您的python版本高于3. +，请运行服务器

python3 manage.py runserver

否则为python 2.7+版

python manage.py runserver

现有Django项目中的语法错误
