pip backup requirements lib in original env
Standard Virtual Environment ( venv or virtualenv ) The "original" and most common way to back up a virtual environment is not to copy the folder itself (which often breaks due to hardcoded paths), but to "freeze" its state into a list of dependencies. Medium +4 Export (Backup): Run this command inside your activated environment. bash pip freeze > requirements.txt 請謹慎使用程式碼。 This creates a file named requirements.txt containing every package and its exact version. Restore: To recreate the environment elsewhere, create a new venv and run: bash pip install -r requirements.txt 請謹慎使用程式碼。
