We publish platform-specific wheels to PyPI. They are built against different arch, CPython and OS versions so in 99% of cases, you may seamlessly install ansible-pylibssh not needing any external dependencies on your system.
It should be enough for you to just have Python 2.7 or 3.5+ and a recent pip installed.
Please make sure you have the latest version of pip before installing ansible-pylibssh.
If you have a version of pip older than 8.1, it’ll be unable to pick up OS-specific Python package distributions from PyPI and will try to fall back to building it from source which would require more extra dependencies to succeed. You can upgrade by following pip’s upgrade instructions.
To install ansible-pylibssh, just run:
$ pip install --user ansible-pylibssh
Avoid running pip with sudo as this will make global changes to the system. Since pip does not coordinate with system package managers, it could make changes to your system that leaves it in an inconsistent or non-functioning state. This is particularly true for macOS. Installing with --user is recommended unless you understand fully the implications of modifying global files on the system.
Installing ansible-pylibssh from source is a bit more complicated. First, pylibssh requires libssh to be compiled against, in particular, version 0.9.0 or newer. Please refer to libssh Downloads page for more information about installing it. Make sure that you have the development headers too.
Another essential build dependency is GCC. You may already have it installed but if not, consult with your OS docs.
Once you have the build prerequisites, the following command should download the tarball, build it and then install into your current env:
$ pip install \ --user \ --no-binary ansible-pylibssh \ ansible-pylibssh
Since our build processes are tox-centric, let’s install it first:
$ python -m pip install 'tox >= 3.19.0' --user
Now, let’s grab the source of ansible-pylibssh:
$ git clone https://github.com/ansible/pylibssh.git ~/src/github/ansible/pylibssh $ # or, if you use SSH: $ git clone firstname.lastname@example.org:ansible/pylibssh.git ~/src/github/ansible/pylibssh $ cd ~/src/github/ansible/pylibssh [dir:pylibssh] $
Finally, you can build the dists for the current env using:
[dir:pylibssh] $ tox -e build-dists
If you want to generate the whole matrix of
manylinux-compatible wheels, use:
[dir:pylibssh] $ tox -e build-dists-manylinux # with Docker [dir:pylibssh] $ # or with Podman [dir:pylibssh] $ DOCKER_EXECUTABLE=podman tox -e build-dists-manylinux
