levoai-gevent 21.12.1.dev0

Supported Platforms

This version of gevent runs on Python 2.7.9 and up, and many versions of Python 3 (for exact details, see the classifiers on the PyPI page or in setup.py). gevent requires the greenlet library and will install the cffi library by default on Windows. The cffi library will become the default on all platforms in a future release of gevent.

This version of gevent also runs on PyPy 7.3.7 (7.3.6 for PyPy2) or above. On PyPy, there are no external dependencies.

gevent is tested on Windows, macOS, and Linux, and should run on most other Unix-like operating systems (e.g., FreeBSD, Solaris, etc.)

Installation

gevent and greenlet can both be installed with pip, e.g., pip install gevent. Installation using buildout is also supported.

On Windows, macOS, and Linux, both gevent and greenlet are distributed as binary wheels.

Extra Dependencies

There are a number of additional libraries that extend gevent’s functionality and will be used if they are available. All of these may be installed using setuptools extras, as named below, e.g., pip install gevent[events].

events

In versions of gevent up to and including 20.5.0, this provided configurable event support using zope.event and was highly recommended.

In versions after that, this extra is empty and does nothing. It will be removed in gevent 21.0.

dnspython

Enables a pure-Python resolver, backed by dnspython. On Python 2, this also includes idna. They can be installed with the dnspython extra.

monitor

Enhancements to gevent’s self-monitoring capabilities. This includes the psutil library which is needed to monitor memory usage. (Note that this may not build on all platforms.)

recommended

A shortcut for installing suggested extras together. This includes the non-test extras defined here, plus:

• backports.socketpair on Python 2/Windows (beginning with release 20.6.0);

• selectors2 on Python 2 (beginning with release 20.6.0).

test

Everything needed to run the complete gevent test suite.
