Virtualenv environment replication, virtualenv Environment

In Python development, virtualenv is usually used for Environment isolation to prevent contamination of the local Python environment.

When we have multiple virtual environments, how can we copy the packages from one virtual environment to another?

1. Go to the scripts directory of the original virtualenv variable and export the version information of the packages installed in this environment

Pip freeze> requirements.txt

2.In a new virtual environment, copy the file requirements.txt that is not exported to the scripts directory and run the installation command.

Pip install-r requirements.txt
