virtualenvwrapper

问题 Short Question Using virtualenv / virtualenvwrapper is it possible to add a prefix to the python call that linked to a specific virtual environment? Background I would like to have multiple virtual environment using a brew installed Python 2.7, but some running in 64 bit mode and the others 32bit mode. Below I have the typical setup for my OS X development. The specific prefix I would like to add to the python call is the arch -i386 to force python to run as 32 bit mode. Again the most

问题 I tried to use virtualenvwrapper to create a virtualenv with both python2 and python3 Per virtualenv with python2 and python3 via Homebrew I hoped this would work: (The name of the virtualenv is 'double') mkvirtualenv double -p `which python` mkvirtualenv double -p `which python3` It mentions that Not overwriting existing python script both/bin/python (you must use both/bin/python3.4) But it that does not seem to be true.

问题 Sometimes I get errors that I suspect are the result of my Django app using globally installed Python modules/Django apps instead of those within its virtualenv. Is there a way to check whether my app's virtualenv was created with '--no-site-packages' without having to delete it, then re-create it as follows? deactivate rmvirtualenv my_env mkvirtualenv my_env --no-site-packages workon my_env pip install -r requirements.txt Surely there must be a better way! Thanks. 回答1: There's a file in <env
