This pulls in Drake via the Bazel workspace mechanism.
For an introduction to Bazel, refer to Getting Started with Bazel.
First, install the required Ubuntu packages:
Then, to build and test all apps:
bazel test //...
As an example to run a binary directly:
bazel run //apps:simple_logging_example
You may also run the binary directly per the
bazel-bin/... path that the
above command prints out; however, be aware that your working directories may

You may generally want to stick to using
bazel run when able.
By default, Python 2 is the Python interpreter that Drake will use when built with Bazel. To see which Python versions are supported, see the supported configurations.

An example of using Python 3 on Ubuntu Bionic:
build --python_path=/usr/bin/python3 build --action_env=DRAKE_PYTHON_BIN_PATH=/usr/bin/python3
Note: If your project needs to support multiple Python versions, it is
suggested to use Bazel's
--config mechanism. In Drake,
--config=python3 is used.
