我对Python和Django非常陌生，我试图找到正确的方法来建立一个基本的Django项目来开始学习它。

下面是我的Python和Django版本的详细信息-

​

​

查找版本的命令-

代码语言：javascript
运行
复制
python --version

pip --version

python -m django --version

我使用以下命令在其中创建一个项目和一个模块- django-admin cd djangoCrud/ python manage.py startapp

I能够使用以下命令-运行该项目

代码语言：javascript
运行
复制
python manage.py runserver

然后，我读到我需要一个进一步开发的虚拟环境，为此我使用了以下命令来创建和运行它-

代码语言：javascript
运行
复制
pip install virtualenv
virtualenv env
. env/bin/activate

但是当我试图在激活环境后运行manage.py文件时，

它会抛出一个错误-

代码语言：javascript
运行
复制
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

​

但是我可以在不激活环境的情况下运行manage.py

，有人能指点我出什么事了吗?我怎么解决这个问题？

尝试步骤-

代码语言：javascript
运行
复制
pip install virtualenv
virtualenv env
. env/bin/activate
pip install Django
django-admin startproject projectNameHere
python manage.py startapp moduleNameHere
python manage.py runserver

​

​

能够解决，需要的人的正确顺序-

代码语言：javascript
运行

首先，要确保python和pip都是固定的。我确实建议安装python3。

然后通过pip安装python。

然后是pip3 install virtualenv

用virtualenv -p python3 <env_name>创建venv

用source <env_name>/bin/activate激活env

然后，使用django-admin startproject <project-name>创建django项目

然后你可以进行迁移。

python3 manage.py makemigrations

python3 manage.py migrate

一旦完成，您可以继续将超级用户创建为python manage.py createsuperuser <username>

您可以通过它的文档https://www.djangoproject.com/start/获得一种描述更多的方法

PS:- python3和python2没有区别，如果python3是缺陷版本，因为python命令将被符号链接到/usr/bin/python 3

创建虚拟服务器时，必须再次设置python。

首先在virtualenv中安装django：

代码语言：javascript
运行
复制
source env/bin/activate
pip install django

此外，如果您有其他软件包，您必须安装它。

virtualenv是一个独立的环境，必须自行设置。
