virtualenv 下使用ipython

~/.bashrc中配置

#virtualenv wrapper

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

alias vipython="python -c 'import IPython; IPython.terminal.ipapp.launch_new_instance()'"

workon env

vipython

即可

django 中：

python manage.py shell -i ipython

来启动ipython，而不是直接ipython manage.py shell，这样会提示MultipleInstanceError: Multiple incompatible subclass instances of InteractiveShellEmbed are being created.
An exception has occurred, use %tb to see the full traceback.
