OS X (Mavericks) has Python 2.7 stock installed. But I do all my own personal Python stuff with 3.3. I just flushed my 3.3.2 install and installed the new 3.3.3. So I need to install pyserial again. I can do it the way I've done it before, which is: Download pyserial from pypi.

Some commonly used packages are not available through the PPA. Xbox 360 neighborhood download mediafire. You can install them through
pip
:Anaconda (cross-platform)
First, create a new Python environment for OpenSesame (optional):
Next, add the relevant channels (
cogsci
) and (conda-forge
) and install all relevant packages:Some packages are not available through conda. You can use
pip install
for these.Once you have installed all packages, you can simply run OpenSesame by (after having activated the correct environment) running:

Tips
Which version of Python to use?
OpenSesame is currently built with Python 3.7.6 (standard package) and Python 2.7.15.
When (not) to update?
- Update while developing and testing your experiment; it is always best to use the latest version of OpenSesame.
- Do not update while running an experiment; that is, do not update while you are collecting data.
- Run an experiment with the same version of OpenSesame that you used for developing and testing.
Manually upgrading packages
Python 3.3 Free Download
- OpenSesame is a regular Python environment, and you can upgrade packages with
pip
orconda
as described here:

Tips for system administrators
- When a new major version of OpenSesame is released (with a version ending in 0, e.g. 3.1.0), it is generally followed quickly by one or two maintenance releases (e.g. 3.1.1 and 3.1.2) that address major bugs. Therefore, if you are installing OpenSesame on systems that you do not update often, it is best to wait until the second or third maintenance release (e.g. 3.0.2, 3.1.3, etc.). That way you minimize the risk of rolling out a version of OpenSesame that contains major bugs.
- The Windows installer allows you to silently install OpenSesame using the
/S
flag.
