Installing Asteval

Requirements

Asteval is a pure Python module. The latest stable version is 1.0.5, which supports Python 3.8 through 3.12.

Installing asteval requires setuptools and setuptools_scm. No other libraries outside of the standard library are required. If numpy and numpy_financial are available, asteval will make use of these libraries. Running the test suite requires the pytest, coverage, and pytest-cov modules, deployment uses build and twine, and building the documentation requires sphinx.

Python 3.8 through 3.12 are tested on Windows, MacOS, and Linux, with and without numpy installed. Older Python versions have generally been supported by asteval until they are well past the end of security fixes. That is, while asteval is no longer tested with Python 3.7, the latest release may continue to work with that version.

Support for new versions of the Python 3 series is not guaranteed until some time after the official release of that version, as we may not start testing until late in the “beta” period of development. Historically, the delay has not been too long, though asteval may not support newly introduced language features.

Installing with pip

The latest stable version of asteval is 1.0.5 and is available at PyPI or as a conda package. You should be able to install asteval with:

pip install asteval

It may also be available on some conda channels, including conda-forge, but as it is a pure Python package with no dependencies or OS-specific extensions, using pip should be the preferred method on all platforms and environments.

Development Version

The latest development version can be found at the github repository, and cloned with:

git clone https://github.com/lmfit/asteval.git

Installation from the source tree on any platform is can then be done with:

pip install .
