linux操作系统不能识别在windows操作系统中用Pycharm构建的venv

Linux operating systems cannot directly recognize a Python virtual environment (venv) created in Windows due to differences in file paths and executable formats between the two operating systems. When moving a project from Windows to Linux, you would typically need to recreate the virtual environment on the Linux system. This involves copying your project files (excluding the venv directory) to the Linux system, and then running python -m venv venv and pip install -r requirements.txt commands in your project directory on the Linux system to recreate the environment and install all required dependencies.
