There appears to be a bug in setuptools, triggered by running "python setup.py sdist" with setuptools==11.3 in that python's environment, on a project whose setup.py has a setup_requires= that requests setuptools >= 28.8.0. When setuptools is upgraded from inside setup.py, it gets into a weird hybrid state where it's using setup() keyword-argument plugins from the newer setuptools, but those plugins reference functions that aren't present in the older setuptools, and the sdist command fails with an import error (module object has no attribute 'check_specifier'). We don't actually need the sdist: all our tox test environments use "skip_install = true", because we install tahoe via the "deps" line (so we can get the `[test]` extra, and get a faster symlink-ish "editable" install). That install uses "pip", which uses the pip inside the new virtualenv, which either uses a newer version of setuptools (dependent upon what version of "virtualenv" was installed in the parent environment, next to tox) or somehow allows setuptools to be upgraded without exposing this weird broken hybrid state. Either way, skipping the sdist seems to fix this problem. refs ticket:2910 https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2910
Tahoe-LAFS
Tahoe-LAFS is a Free and Open decentralized cloud storage system. It distributes your data across multiple servers. Even if some of the servers fail or are taken over by an attacker, the entire file store continues to function correctly, preserving your privacy and security.
For full documentation, please see http://tahoe-lafs.readthedocs.io/en/latest/ .
INSTALLING
There are three ways to install Tahoe-LAFS.
using OS packages
Pre-packaged versions are available for several operating systems:
- Debian and Ubuntu users can
apt-get install tahoe-lafs - NixOS, NetBSD (pkgsrc), ArchLinux, Slackware, and Gentoo have packages available, see OSPackages for details
- Mac and Windows installers are in development.
via pip
If you don't use an OS package, you'll need Python 2.7 and pip. You may also need a C compiler, and the development headers for python, libffi, and OpenSSL. On a Debian-like system, use apt-get install build-essential python-dev libffi-dev libssl-dev python-virtualenv. On Windows, see docs/windows.rst.
Then, to install the most recent release, just run:
pip install tahoe-lafs
from source
To install from source (either so you can hack on it, or just to run pre-release code), you should create a virtualenv and install into that:
git clone https://github.com/tahoe-lafs/tahoe-lafs.gitcd tahoe-lafsvirtualenv --python=python2.7 venvvenv/bin/pip install --upgrade setuptoolsvenv/bin/pip install --editable .venv/bin/tahoe --version
To run the unit test suite:
tox
You can pass arguments to trial with an environment variable. For example, you can run the test suite on multiple cores to speed it up:
TAHOE_LAFS_TRIAL_ARGS="-j4" tox
For more detailed instructions, read docs/INSTALL.rst .
Once tahoe --version works, see docs/running.rst to learn how to set up your first Tahoe-LAFS node.
