PredictionIO: Pio command not found after install

I am guessing that somehow PredictionIO didn't setup the path variables properly.

I used method 2 to install PredictionIO from this link here: PredictionIO

Everything installed correctly but when I typed in pio it says command not found. This is what I see:

When I try to start pio from finder I get this:

Kind of lost, what am I doing wrong here?

Solution

  • The solution is to edit your PATH environment variable. You can do it directly in the shell:

    $ export PATH=/Users/yourname/PredictionIO/bin:$PATH

    However it will be set only as long as the session lasts. To make it permanent, you have to edit your bash profile file. I don't know how it is called on MacOS. On my Ubuntu, it is the .profile file. It is usually .profile, or .bash_profile or something like that.

    $PATH is probably set in this file, so find where and edit.

    My .profile file has a part in it that reads:

    # set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:/opt/java/jdk1.8.0_45/bin:$PATH"
fi

    I would change it to (even though it looks weird because it mixes your MacOS path and my Ubuntu ones):

    # set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:/opt/java/jdk1.8.0_45/bin:/Users/yourname/PredictionIO/bin:$PATH"
fi
