A concise guide to creating a virtual environment using pipenv

Simple and easy-to-understand guide: Use pipenv to build a virtual environment

Introduction:
In Python development, we often need to use virtual environments to isolate project dependencies libraries to ensure that dependencies between different projects do not interfere with each other. pipenv is a powerful and user-friendly tool that can help us easily create and manage Python virtual environments. This article will introduce in a simple and easy-to-understand way how to use pipenv to build a virtual environment, and provide specific code examples to help beginners get started quickly.

Step 1: Install pipenv
First, we need to install the pipenv tool. Run the following command on the command line:

$ pip install pipenv

This will automatically install the latest pipenv version and wait for the installation to complete.

Step 2: Create a virtual environment
In your project directory, open the command line and run the following command:

$ pipenv --python 3.7

This will create a file named Pipfile, where Records the Python version and dependency package information used by your project.

Step 3: Install project dependencies
In the virtual environment created in step 2, we can use pipenv to install the dependent libraries required for the project. For example, if we need to install the requests library, we can run the following command:

$ pipenv install requests

This will install the requests library in the virtual environment and add the corresponding dependencies in the Pipfile.

Step 4: Enter the virtual environment
After successfully installing the dependencies, we need to enter the virtual environment in order to run our Python code in this environment. Run the following command to enter the virtual environment:

$ pipenv shell

This will activate the virtual environment and change the command prompt to the name of the virtual environment.

Step 5: Exit the virtual environment
After using the virtual environment, you can exit the virtual environment by running the following command:

$ exit

This will exit the virtual environment and open the command prompt Return to original state.

Step 6: Uninstall the virtual environment
If you no longer need to use the virtual environment, you can uninstall it by running the following command:

$ pipenv --rm

This will delete the virtual environment under the current project and its related documents.

Summary:
Building a virtual environment using pipenv is very simple and only requires a few simple commands to complete. By using pipenv, we can easily manage the project's dependent libraries, thereby improving development efficiency. I hope that the simple and easy-to-understand guide and specific code examples provided in this article will be helpful to beginners, so that everyone can quickly get started using pipenv. Systematic learning of pipenv will be a great tool for you to develop Python projects. I wish you all a happy study!
