| |
| 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| |
