问题描述

我无法在我的 macbook pro 上的 python3 上安装和配置虚拟环境.我试图为我的下一个项目安装和试用 django，但这里开始出现问题.

I can't install and configure virtual environment on python3 on my macbook pro. I was trying to install and try django for my next project but here problems started arising.

推荐答案

在目录下安装虚拟环境

在主目录根目录添加以下命令创建环境:

In the main directory root add the following command to create the environment:

$ python3 -m venv venv 此代码将在根目录中创建一个名为 venv 的文件夹.基本上是虚拟环境文件夹.

$ python3 -m venv venv this code will create a folder called venv in the root. Which basically is the virtual environment folder.

然后添加以下命令激活虚拟环境:

Then add the following command to activate the virtual environment:

$ source venv/bin/activate

your_project_folder/
 |
 |-- your_main_app_folder/
 |         |
 |         |--Folder_with_controllers/
 |         |            settings.py
 |         |            urls.py
 |         |            ...
 |         | 
 |         |--App_folder/
 |         |--Other_app_folder/
 |
 |--venv/

如果代码运行良好，您的 bash 应该如下所示:

If the code works fine your bash should look like this:

(venv) your_project_folder %

激活您的环境后，您现在可以安装 django 和其他软件包.

After activated your environment you can now install django and other packages.

ps:确保您安装并激活虚拟环境文件夹不在 your_main_app_folder 中.

p.s.: make sure you instal and activate the virtual environment folder not in the your_main_app_folder.
