MacPorts

• installing MacPorts

• find installation information here link
• find general information here link
• download and follow the instructions
• macport installs in /opt/local so add to your path "export PATH=/opt/local/bin:/opt/local/sbin:$PATH"
• after a major OS upgrade you will need to install a new MacPorts

• using MacPorts basic commands

• you will need to run all commands as sudo
• general commands

port version

sudo port selfupdate

port installed

port outdated

port upgrade

port uninstall code_name

port activate code_name

• search for particular codes, in this case for python versions, generally or installed on this machine

port search --name --line --glob 'python*'

port installed 'python*'

port select --list python

port select --set python3 python37

port select --set python2 python27

port select --set python python37 or which ever version you want

• problems

the mac has a preinstalled version of python in /user/local/bin

python.org installs in /Library/Frameworks/Python.framework/Versions/3.5/bin and so on

macports installs in /opt/local/bin

to find out which version is being used type "which python"

to find out the version of python used "python -V"

to ensure the macports version is used in your $PATH make sure /opt/local occurs before /user/local

sometimes other initiating files add things to your path, so even with the path variable below if I echo $PATH, /usr/local comes up first

switch your script to PATH=/Users/tricia/bin:$PATH etc

for example

PATH=$PATH:/Users/tricia/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/Applications/anaconda/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/Users/tricia/bin/repESP/scripts:

[tricia@dyn1243-210]/Users/tricia $ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Library/TeX/texbin:/Users/tricia/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/Applications/anaconda/bin:/Users/tricia/bin/repESP/scripts::/Users/tricia/bin/amber16/bin:/Applications/gauopen:/Applications/g16/bsd:/Applications/g16
