To install pgfplots for OSX Yosemite? Old discussion about this topic for OSX Lion here.
However, I think there is no good answer to this topic, since pgfplots is not already installed so not only a .sty file problem, like Alan writes there. 

I am trying to run this script here but get the error about the missing pgfplots, after the generation of the Liste.dat:



I run ls /usr/local/texlive/2014/texmf-dist/scripts/pgfplots/ and get 

matlab2pgfplots.m   pgf2pdf.sh  matlab2pgfplots.sh  pgfplots.py. 


This suggests me that have the command but the error is internal in pgfplots.

I reinstall the system and run the command sudo tlmgr install --reinstall pgfplots but I get the some error message as above. 

How can you install pgfplots in OSX Yosemite?
pgfplots is available as part of MacTeX:





To forcefully reinstall it from the command line, you can use

sudo tlmgr install --reinstall pgfplots
