PyCharm configuration virtual environment is a method to create an independent running environment in Python. It allows users to manage multiple Python environments on the same computer and avoid dependency conflicts between different projects. The virtual environment can isolate the installation paths of the Python interpreter and third-party libraries, allowing different projects to use different Python versions and library versions.

The specific steps for PyCharm to configure the virtual environment include:

1. Open PyCharm, enter the "File" menu, and select "Settings".

2. In the settings window, expand the "Project" node, and then select "Project Interpreter".

3. Click the " " icon in the upper right corner and select "Virtualenv Environment" in the pop-up window.

4. Enter the name of the virtual environment in the "Name" field, and select the path of the virtual environment in the "Location" field.

5. Check the "Use existing Python interpreter" option and select the installed Python interpreter from the drop-down list below.

6. Click the "OK" button, and PyCharm will automatically create and configure the virtual environment.

7. Activate the virtual environment: In the status bar at the bottom of PyCharm, you can see the currently used Python interpreter path. If you want to switch to another virtual environment, you can right-click the Python interpreter path in the status bar, select the "Switch to" option, and select the virtual environment you want to switch in the pop-up window.

8. Install dependencies in the virtual environment: Enter the "File" menu, select "Settings", expand the "Project" node, and then select "Project Interpreter". In the "Project Interpreter" window on the right, you can see the virtual environment used by the current project and a list of its installed dependent libraries. If you need to install a new dependent library, you can click the " " button in the upper right corner of the window and select the dependent library to be installed in the pop-up window.

It should be noted that when configuring a virtual environment, you need to first ensure that Python and Virtualenv have been installed. At the same time, when selecting the path of the virtual environment, it is recommended to use relative paths instead of absolute paths to avoid unnecessary errors. In addition, different projects may need to use different virtual environments, and different virtual environments can be created and configured in different projects.

In short, PyCharm's virtual environment configuration is very convenient and flexible, and can be configured differently according to different needs.
