A simple utility to manage multiple virtual python environments and activate them when you need it
$ pip install inenvCreate a config file called inenv.ini in your project root directory:
[webproject]
deps: file:requirements.txt
[service]
deps: requests==1.4 file:subproject/app/requirements.txtExample Usage (in any directory of the project):
# Initialize inenv
inenv init webproject
# Note this will tell you to add a file to source in bash, if you want to switch envs in your shell, do this.
# Switches your current env to webproject
inenv webproject python
inenv service
pip freeze
# Runs `python manage.py syncdb` in the webproject venv
# Use posix style -- to pass all args
inenv webproject -- python manage.py syncdb --hello Python Lib
from inenv.venv import VirtualEnv
venv = VirtualEnv('webproject', '/User/.virtualenvs')
venv.create_if_dne()
venv.delete()
venv.create_if_dne()
venv.install_requirements_file('requirements.txt')
venv.install_deps(['requests==2.0'])
venv.activate()
subprocess.check_output(['pip','freeze'])
venv.deactivate()
subprocess.check_output(['pip','freeze'])
venv.run(['pip','freeze'])
with VirtualEnv('webproject', '/User/.virtualenvs') as venv:
subprocess.check_output('python --version')
from inenv.inenv import InenvManager
manager = InenvManager("/project/inenv.ini") # file optional will look for one
venv = manager.get_prepped_venv('webproject')
# Sase as VirtualEnv aboveFun (don't do this; it's unreliable and dangerous):
