Python import and export dependent package commands
The program must include a requirements.txt file to record all dependent packages and their precise version numbers. If you want to regenerate the virtual environment on another computer, the importance of this file is reflected, such as the computer used when deploying the program. pip can use the following command to automatically generate this file
pip freeze requirements.txt
If you want to create a complete copy of this virtual environment, you can create a new virtual environment and run the following commands on it:
pip install -r requirements.txt
