Hi Bill, Linux is designed to run multiple versions of Python simultaneously. e.g. Py2 and Py3. Or at least, the Debian based Distros are. That's not the case for some others. I can't speak to how Arch, Slack, Fedora etc manage multiple Python version installs. If you call python -V on a standard Ubuntu / Debian System, you will most like get 2.7.x back as the version. If calling python3 -V, it should return 3.3.x or 3.4.x or later. Scripts requiring python3, should list it in the shebang stating as such: #!/usr/bin env python3 Most of the Debian based distros are still locked to Python2 as it's core Python, but that is changing. Ubuntu and Debian are agressively updating to Python3, but there are 1000's of package deps on Python2, so it's taking a while. Here's another issue. Some distro's do not have Python2 installed as a default package (Arch for example). So, if I were to install python3, and then type python-V .. it would render the python3 version. Needless to say, the transition from Py2 and Py3 has been messy for all OS's, not just Linux. The only way to Isolate Py2 and Py3 in Windows is through a Python Virtualenv which ensures both Python versions are not on the path, which is tricky when using the same Makefile to build both Docs and the App itself, but it can be done. 73's Greg, KI7MT On 04/28/2015 05:07 PM, Bill Somerville wrote: > On 28/04/2015 23:57, KI7MT wrote: >> Hi Bill, > Hi Greg, >> >> Yes, AsciiDoc works with Python2.5 through the latest Python2 which is >> Python2.7.9 I believe.
