Openstack 1:配置开发环境 Setting Up a Development Environment

On Ubuntu:

sudo apt-get install python-dev libssl-dev python-pip git-core libxml2-dev libxslt-dev pkg-config libffi-dev libpq-dev libmysqlclient-dev

Grab the code from GitHub:

git clone https://github.com/openstack/nova.git
cd nova

The unit tests will run by default inside a virtualenv in the .venvdirectory. Run the unit tests by doing:

./run_tests.sh

The first time you run them, you will be asked if you want to create a virtualenvironment (hit “y”):

No virtual environment found...create one? (Y/n)

You can manually install the virtual environment instead of havingrun_tests.sh do it for you:

python tools/install_venv.py

This will install all of the Python packages listed in therequirements.txt file and also those listed in thetest-requirements.txt file into your virtualenv. There willalso be some additional packages (pip, setuptools, greenlet) that areinstalled by the tools/install_venv.py file into the virutalenv.

If all goes well, you should get a message something like this:

Nova development environment setup is complete.

To activate the Nova virtualenv for the extent of your current shell sessionyou can run:

$ source .venv/bin/activate

Or, if you prefer, you can run commands in the virtualenv on a case by casebasis by running:

$ tools/with_venv.sh <your command>
