Note that with the latest update for Pharo 2.0 ([update 2.0] #20185)
or the latest one click image
https://ci.lille.inria.fr/pharo/view/Pharo%202.0/job/Pharo-2.0/lastSuccessfulBuild/artifact/Pharo-2.0-one-click.zipyou can easily load ScriptManager using
Tools -> ConfigurationBrowser -> click on "ScriptManager"
and select "Install configuration (Stable version)"
After loading go to "Tools" -> "ScriptManager"
Note that ScriptManager is now using Fuel for
exporting/importing which is not compatible with the
old ReferenceStream.
It now exports into *.fuel files instead of *.obj.
Have fun
