Installation

Latest Release

Using the Package Installers

The easiest way to install Crispy on Windows and macOS operating systems is to use the installers provided on the downloads page of the project.

Using pip

Pip is the package manager for Python, and before you can use it to install Crispy, you have to make sure that you have a working Python distribution. On macOS and Windows, you can install Python using the official installers. In particular, for Windows, you should install the 64-bit version of Python and make sure that you select to add Python to the system PATH during the installation.

python3 -m pip install crispy

After the installation finishes, you should be able to start the program from the command line:

crispy

If you have problems running the previous command, it is probably due to not having your PATH environment variable set correctly.

export PATH=$HOME/.local/bin:$PATH
