Flask Getting started with Flask Installation - Development
Example
If you want to develop and contribute to the Flask project, clone the repository and install the code in development mode.
git clone ssh://github.com/pallets/flask
cd flask
python3 -m venv env
source env/bin/activate
pip install -e .
There are some extra dependencies and tools to be aware of as well.
sphinx
Used to build the documentation.
pip install sphinx
cd docs
make html
firefox _build/html/index.html
py.test
Used to run the test suite.
pip install pytest
py.test tests
tox
Used to run the test suite against multiple Python versions.
pip install tox
tox
Note that tox only uses interpreters that are already installed, so if you don't have Python 3.3 installed on your path, it won't be tested.
