Appendix C. Installing Mercurial from Source
On a Unix-Like System
If you are using a Unix-like system that has a sufficiently recent version of Python (2.3 or newer) available, it is easy to install Mercurial from source. Here’s how:
Download a recent source tarball from http://www.selenic.com/mercurial/download.
Unpack the tarball:
gzip -dc mercurial-MYVERSION.tar.gz | tar xf -
Go into the source directory and run the installer script. This will build Mercurial and install it in your home directory.
cd mercurial-MYVERSION python setup.py install --force --home=$HOME
Once the install finishes, Mercurial will be in the bin subdirectory of your home directory. Don’t forget to make sure that this directory is present in your shell’s search path.
You will probably need to set the
PYTHONPATH environment variable so that the Mercurial
executable can find the rest of the Mercurial packages. For example, on my laptop, I have set it to
/home/bos/lib/python. The exact path that you will need to
use depends on how Python was built for your system, but should be easy
to figure out. If you’re uncertain, look through the output of the
installer script above, and see where the contents of the
mercurial directory were installed to.
