Visual Studio Code Venv 使用错误 Python 版本

Question

I have Python 3.4 and 3.9 installed. I chose the former through the Command Palette and then (also through the Command Palette) created a virtual environment with Venv. I create a new terminal, enter python --version, and it says 3.9 instead of 3.4.

How do I go about fixing this?

Answer 1

There are multiple python environments on your machine, if you have created a virtual environment, you should run these commands after activation. If you execute the python command in a terminal where the virtual environment is not activated, the displayed version will be the one configured in the system environment variable path .

The correct way is:

1. Create a virtual environment
2. Activate the virtual environment
3. Execute python commands

There are two ways to activate a virtual environment:

• After creating the virtual environment use the following command to activate

  .venv\scripts\activate

• Or select the virtual environment interpreter in the select interpreter panel, and then create a new terminal to automatically activate the environment.

  

In vscode, the interpreter version you choose for python will always be displayed in the lower right corner.

See the Environments documentation for more details.
