Hello together,

I was trying to use the interactive mode of the OptaWeb VRP

in the actual version (8.4.1) and the version of the intro video (7.38.0):

https://www.youtube.com/watch?v=rEeAML74oWo&t=204s

In both version I run the command "./runLocally.sh -i" within the bin-Folder

in both cases the following error occured:

line 273: readarray: command not found

In line 273 the interactive function gets called. In case of no given value it should trigger the select scheme like in the video.

Is there anything I missed?

The default Belgium demo works.

Greetings,

Felix

I am guessing you are using MacOS; there is a known issue where `runLocally.sh` does not work on MacOS due to the Bash version used (which doesn't come with the built-in readarray function): https://issues.redhat.com/browse/PLANNER-2036 .

As a workaround, you can try using an updated version of bash, or download the openstreet maps files yourself and pass them to the Jar as arguments (it look like this):

```

java -jar optaweb-vehicle-routing-standalone/target/optaweb-vehicle-routing-standalone-8.4.0-SNAPSHOT.jar --app.demo.data-set-dir=./dataset --app.persistence.h2-dir=./db --app.persistence.h2-filename=${osm_file%.osm.pbf} --app.routing.engine=graphhopper --app.routing.osm-dir=./openstreetmap --app.routing.gh-dir=./graphhopper --app.routing.osm-file=$osm_file

```

Thanks for the hint with the bash version on macOS!👍

The script has been updated to be compatible with the old Bash version found on macOS: https://github.com/kiegroup/optaweb-vehicle-routing/pull/462.

I know *This project is no longer maintained.*
I followed the video https://www.youtube.com/watch?v=rEeAML74oWo&t=107s

Changed the script runLocally.sh why cmd is closing immeadiately.

The folder is created
I see following problem

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.se/docs/sslcerts.html

I have Windows 10
I will not spend too much time on it, I wanted just to see how does it work
Anyway I am working on https://github.com/kiegroup/optaplanner-quickstarts/tree/stable/use-cases/vehicle-routing
