Welcome to the Tahoe project, a secure, decentralized, fault-tolerant filesystem.
See the about page for more information.
This procedure has been verified to work on Windows, Cygwin, Mac, Linux, Solaris, and FreeBSD. It's likely to work on other platforms. If you have trouble with this install process, please write to the tahoe-dev mailing list, where friendly hackers will help you out.
Follow the instructions on the Python download page to download and install Python v2.4.2 or greater, but not Python v3 -- it has to be Python v2.
Download a recent zip file from here:
http://allmydata.org/source/tahoe/snapshots
Unpack the zip file and cd into the top-level directory.
Run python setup.py build to install the tahoe executable into a subdirectory of the current directory named bin.
Optionally run python setup.py test to verify that it passes tests.
Run bin/tahoe --version to verify that the executable tool runs and prints out the right version number.
Now you have the Tahoe source code installed and are ready to use it to form a decentralized filesystem. The tahoe executable in the bin directory can configure and launch your Tahoe node. See running.html for instructions on how to do that.
For more details, including platform-specific hints for debian, windows, and Mac systems, please see the InstallDetails wiki page.
