Linux and Mac OS X
The Transifex Client is written in Python and most Unix-based systems have Python pre-installed. The easiest way to install it is with pip. Like most Python development tools, you probably want to install it inside a virtualenv, but you can surely install it as root using sudo.
root# pip install transifex-client
If you don't have pip installed, you can install it as follows:
user% curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py root# python get-pip.py
root# pip install --upgrade transifex-client
Installing from source
Just grab the code from GitHub and run the install script:
user% git clone http://code.transifex.com/transifex-client user% cd transifex-client root# python setup.py install
The Transifex Client is also available for Windows. You can download the latest version from http://files.transifex.com/transifex-client/0.10/tx.exe. This executable is standalone and does not need to be installed. You can find more details for Windows here.
