Temporarily update README install instructions

[johnsca]

Until libjuju is released to pypi, our instructions need to include
installing using the wheelhouse. Hopefully this can be reverted very
soon.

I don't like telling people to install in their system Python. :-/

This command (minus the sudo) fails in a virtualenv, as it can't find zookeeper.h (probably a lib dir missing from the include path).

[petevg]

Would prefer:

git clone https://github.com/juju-solutions/matrix.git
cd matrix
tox -r 
source .tox/py35/bin/activate

[johnsca]

There are instructions for installing in a venv further down. The point of the default install instructions is to install at the system (or container) level.

A snap for this would be good, but it would have to be unconfined. It's worth looking in to, though, so I created #48

zookeeper.h sounds like its pulling the old python (pre-juju 1.0) bindings that still are in pip and called juju. If you have that sitting around somewhere it would try to build the zookeeper bindings, but nothing modern uses it

This still fails (on a freshly minted Xenial LXD with python3-pip and git installed)

I was missing the --no-index to prevent it from picking up the old juju lib. Please try again.

Thanks

[petevg]

Hooray for working things!

Would still prefer evangelizing virtualenvs in all the places, but I can see cutting it out for simplicity :-)

[petevg]

+1, as --no-index solved all my problems.

[sparkiegeek]

Works much better. Confirmed I can install matrix on a fresh Xenial LXD following these instructions.
