Mac and Linux users may need to use “sudo” before the install commands. But use virtualenv if you don’t want to sudo – it’s great.
Best Method: Pip¶
This will download and install Complexity:
$ pip install complexity
This method requires an installer tool called pip, which you can get from http://www.pip-installer.org/.
Don’t worry, you can later uninstall Complexity like this:
$ pip uninstall complexity
Alternate Method 1: Setup.py¶
If you can’t use pip to install Complexity, download the latest Complexity release from https://pypi.python.org/pypi/complexity.
Then unzip and install Complexity:
$ tar xzvf <name of file> $ cd <name of unzipped dir> $ python setup.py install
