SimPy is implemented in pure Python and has no dependencies. SimPy runs on Python 2 (>= 2.7) and Python 3 (>= 3.2). PyPy is also supported. If you have pip installed, just type

$ pip install simpy

and you are done.

Alternatively, you can download SimPy and install it manually. Extract the archive, open a terminal window where you extracted SimPy and type:

$ python install

You can now optionally run SimPy’s tests to see if everything works fine. You need pytest and mock for this:

$ python -c "import simpy; simpy.test()"

Upgrading from SimPy 2

If you are already familiar with SimPy 2, please read the Guide Porting from SimPy 2 to 3.
