C:\Users\Admin\Desktop\venv\Scripts\
And later, in the virtual environment, starts to the manage.py runserverin the folder:
后来，在虚拟环境中，开始到manage.py runserver文件夹中：

You can activate your virtualenv and then start server using a bat file. Copy this script in to a file and save it with .bat extension (eg. runserver.bat)
您可以激活您的 virtualenv，然后使用 bat 文件启动服务器。将此脚本复制到文件中并使用 .bat 扩展名保存（例如 runserver.bat）
@echo off
cmd /k "cd /d C:\Users\Admin\Desktop\venv\Scripts & activate & cd /d C:\Users\Admin\Desktop\helloworld & python manage.py runserver"
Then you can just run this bat file (just double click) to start the server
然后你就可以运行这个bat文件（双击）来启动服务器

If you want call virtualenv'ed Python directly you can do something like this:
如果你想直接调用 virtualenv'ed Python 你可以做这样的事情：
C:\Users\Admin\Desktop\venv\Scripts\bin\python.exe manage.py runserver
Double check python.exelocation on your virtualenv folder - don't remember how it is out of my head. This Python associates itself with the virtualenv and uses its site-packagesby default.
仔细检查python.exe您的 virtualenv 文件夹上的位置 - 不记得我是怎么想的。这个 Python 将自己与 virtualenv 相关联并site-packages默认使用它。

Rather than using strings you can use a caret (^) as described in this question: Long commands split over multiple lines in Windows Vista batch (.bat) file
您可以使用插入符号 (^)，而不是使用字符串，如以下问题中所述：Windows Vista 批处理 (.bat) 文件中的长命令拆分为多行
E.g.
例如
cmd /k cd path/to/activate ^
activate.bat
pip uninstall --yes package ^
pip install git+https://git.server.com/user/project@remote/branch ^
deactivate
will open a venvand uninstall and reinstall a branch of a Git repository. This is a useful pattern for automating deployment of code into a venv.
将打开一个venv并卸载并重新安装 Git 存储库的一个分支。这是将代码自动部署到 venv 的有用模式。

I am using Anaconda 3 and python 3.7.6 on Windows. Had to do this in my .bat file:
我在 Windows 上使用 Anaconda 3 和 python 3.7.6。必须在我的 .bat 文件中执行此操作：
CALL path\to\base\virtual\environment\Scripts\activate.bat path\to\your\virtual\environment [path\to\your\virtual\environment]python.exe path\to\your\script\yoursript.py
CALL path\to\base\virtual\environment\Scripts\activate.bat path\to\your\virtual\environment [path\to\your\virtual\environment]python.exe path\to\your\script\yoursript.py
Without activate.bat nothing works. I was getting an error about mkl-server. This error is described here https://github.com/numpy/numpy/issues/15523. People complained there about conda being broken, i.e. just calling python.exe yoursript.py does not work.
没有 activate.bat 什么都不起作用。我收到关于 mkl-server 的错误。此错误在此处描述https://github.com/numpy/numpy/issues/15523。人们在那里抱怨 conda 被破坏，即仅调用 python.exe yoursript.py 不起作用。
