You can install coverage.py in the usual ways. The simplest way is with pip::
$ pip install coverage
.. ifconfig:: prerelease
To install a pre-release version, you will need to specify ``--pre``::
$ pip install --pre coverage
.. _install_extension:
C Extension
-----------
Coverage.py includes a C extension for speed. It is strongly recommended to use
this extension: it is much faster, and is needed to support a number of
coverage.py features. Most of the time, the C extension will be installed
without any special action on your part.
If you are installing on Linux, you may need to install the python-dev and gcc
support files before installing coverage via pip. The exact commands depend on
which package manager you use, which Python version you are using, and the
names of the packages for your distribution. For example::
$ sudo apt-get install python-dev gcc
$ sudo yum install python-devel gcc
$ sudo apt-get install python3-dev gcc
$ sudo yum install python3-devel gcc
You can determine if you are using the extension by looking at the output of
``coverage --version``::
$ coverage --version
Coverage.py, version |release| with C extension
Documentation at https://coverage.readthedocs.io
The first line will either say "with C extension," or "without C extension."
A few features of coverage.py aren't supported without the C extension, such
as concurrency and plugins.
Installing on Windows
---------------------
For Windows, kits are provided on the `PyPI page`__ for different versions of
Python and different CPU architectures. These kits require that `setuptools`_
be installed as a pre-requisite, but otherwise are self-contained. They have
the C extension pre-compiled so there's no need to worry about compilers.

Checking the installation
-------------------------
If all went well, you should be able to open a command prompt, and see
coverage.py installed properly:
.. ifconfig:: not prerelease
.. parsed-literal::
$ coverage --version
Coverage.py, version |release| with C extension
Documentation at https://coverage.readthedocs.io
.. ifconfig:: prerelease
.. parsed-literal::
$ coverage --version
Coverage.py, version |release| with C extension
Documentation at https://coverage.readthedocs.io/en/coverage-|release|
You can also invoke coverage.py as a module:
.. ifconfig:: not prerelease
.. parsed-literal::
$ python -m coverage --version
Coverage.py, version |release| with C extension
Documentation at https://coverage.readthedocs.io
.. ifconfig:: prerelease
.. parsed-literal::
$ python -m coverage --version
Coverage.py, version |release| with C extension
Documentation at https://coverage.readthedocs.io/en/coverage-|release|
