问题 How do you change the default Virtualenvwrapper prompt? By default, working on a particular virtual environment with a command like "workon <_name_of_env_>" prepends the name of the virtualenv to your prompt. This may work poorly if you're not using a default command prompt. 回答1: If you are working on a custom PS1 (as I when found out this issue), I recommend you to disable prompt change, use export VIRTUAL_ENV_DISABLE_PROMPT=1 (see virtualenv docs), and make your own virtualenv prompt in
