Building OSPREY Server requires some extra Python development tools that are not typically installed by default. Specifically, you’ll need these Python packages:
Tragically, there’s no universal way to install packages in Python. Python has somewhat of
a fragmented ecosystem. But generally the pip tool works well, athough there are many other
alternatives. If you’re a local administrator, you can try the simplest command:
pip install wheel setuptools
which might need a preceeding sudo on Linux. This is how pypi.org recommends
to install packages by default. If you’re not a local administrator, you can do a
“user” installation using pip, which is good for shared computing environments like research clusters:
pip install --user wheel setuptools
Or if the pip command isn’t on your path or is for the older version 2 of Python, you might try pip3 instead.
Or use the Python module invocation instead of calling pip directly from the command line:
python -m pip install wheel setuptools
With that last one, feel free to add the --user flag if you need it. Or switch to the python3
executable if the default python executable ends up being Python 2 for some reason.
On Windows, the Python executable might even be py!
Easy, right?
For more information on the unfolding saga of how to install Python packages in modern times, PyPI has a detailed guide.
Once you’re all set up, run gradle task serverRelease:
./gradlew serverRelease
The built archive should show up in the folder
build/releases/osprey-server-$OS-$VERSION.tbz2,
where $OS desrcibes your operating system,
and $VERSION is the current version of Osprey.
