现有Django项目中的语法错误

Question

我已经安装了现有的Django项目非常第一次，我有启动服务器的问题pythonmanage.pyrunserver

这就是我所做的

1.克隆回购协议，

2.创建虚拟环境

3.Pip安装要求.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，我已经将secrets.sh添加到. gitignore

5.更改设置.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以下结果：

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

想法？

Answer 1

1.检查您的python和django版本是否应与安装的要求兼容。如果您的python版本超过3。使用运行服务器

python3 manage.py runserver

如果python版本为2.7，则为

python manage.py runserver

Answer 2

您试图运行的项目正在使用Python≥ 3.5，但您正在尝试在2.7中运行它。

语法（请求：WSGIRequest）：是一个类型提示。它是在几年前引入的，但只添加到较新版本的Python3中。没有做出任何努力来支持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。这种变化基于操作系统，所以详细的说明可能超出了这个问题的范围，但是已经有很多关于这个主题的建议了。
