In MacOS I have installed Node.js from the following link: http://nodejs.org/download/ (http://nodejs.org/dist/v0.10.29/node-v0.10.29.pkg).
I am using the following code in AppleScript:
do shell script "supervisor \"/Applications/xyz.js\""
But get the following error:
error "sh: supervisor: command not found" number 127
This works fine when run via Terminal like this:
supervisor /Applications/xyz.js
Sounds like your path enviroment variable is setup differently so that inside Applescript it cannot find the application.
For example in applescript ....
do shell script "echo $PATH"
returns
"/usr/bin:/bin:/usr/sbin:/sbin"
But in terminal ...
$ echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
So I'd just add the full path of the executable in applescript and that should fix the problem...
do shell script "/path/to/app/supervisor ...."
Here is an official explaination...
The issue is that which application you tell determines the environment for the shell script — the working directory, environment variables, and so on. Most applications have the same environment, but relying on this is a maintenance risk. If your AppleScript is running in osascript, the working environment comes from the shell osascript was run from, which is completely separate from any other application.
