Hi John,
I think I've to do issue some more "internal" commands to learn what is happening...

this is a comparison between 2 modules, after unloading them and restarting SU:

> sandbox = Sketchup.find_support_file("su_sandbox.rb", "Plugins")
/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox.rb

> dynamic = Sketchup.find_support_file("su_dynamiccomponents.rb", "Plugins")
/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_dynamiccomponents.rb

> load dynamic
true

> load sandbox
File load error (/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox/sandboxmenus.rb);

Hi,
I was learning other plugins at the same time, but now I made the same test after removing the Plugins folder. The problems happens always, from 1st installation (several times). I'm curious about what can be the error.

The last command has thus a shorter output, but the concept is the same:

> Sketchup.extensions.find_all{|e| p [e.name, e.extension_path]};nil
["Advanced Camera Tools", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_advancedcameratools.rb"]
["Dynamic Components", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_dynamiccomponents.rb"]
["Sandbox Tools", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox.rb"]
["Trimble Connect", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_trimble_connect.rb"]
["Photo Textures", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_webtextures.rb"]

what else can I try?

Hi John, sorry for the late reply, but I still am unable to make it work on all the tests that I'm doing (except on a new machine).

The result from the path check is this:

> Sketchup.extensions.find_all{|e| p [e.name, e.extension_path]};nil
["3DArcStudio 3D Tree Maker", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/3darcstudiotree.rb"]
["TT_Lib²", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/TT_Lib2.rb"]
["Advanced Camera Tools", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_advancedcameratools.rb"]
["Bezier Tool", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_bezier.rb"]
["Dynamic Components", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_dynamiccomponents.rb"]
["Sandbox Tools", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox.rb"]
["Shapes Tool", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_shapes.rb"]
["Trimble Connect", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_trimble_connect.rb"]
["Photo Textures", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_webtextures.rb"]
["CleanUp³", "/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/tt_cleanup.rb"]

...don't know so much what to do...
I understand that there are spaces, that can mess up things, but the other extensions have the same situation...

are there some other tests that I can do to understand the (seems small) ruby issue?
thank you!
Filippo

Thank you very much!
unluckily I'm not a ruby programmer, so the syntax is a bit strange for me...

anyway, I had to "unload" the sandbox extension from the Preferences panel, then things begun to be more "responsive" in Ruby console.

Now this is what happens:

> Sketchup.extensions.find_all{|e| p [e.name, e.loaded?]};nil
["Advanced Camera Tools", true]
["Dynamic Components", true]
["Sandbox Tools", false]
["Trimble Connect", true]
["Photo Textures", true]

> sandbox = Sketchup.find_support_file("su_sandbox.rb", "Plugins")
/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox.rb
> load sandbox

...well, it's quite strange... the file is there (sandboxmenus is the only .rb, all the others are .rbs).
Can be the fact that there are spaces in the path? (well, if it was like that, also the other extensions could have had the same issue, and other users too....)

> sandbox = Sketchup.find_support_file("su_sandbox.rb", "Plugins")
/Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox.rb
> load sandbox
true

seems no errors here... (but no sandbox is really loaded, I cannot see the sandbox menus)

Tried to make a VMware virtual machine, just to test, with OSX, and the same DMG is working correctly... strange...

@driven said:

Have you installed the Maintenance release of v16?

If you remove or rename /Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins folder and relaunch SU, a new folder with fresh copies of all the **su_**Extensions will be created for you...

these should have the correct permissions needed by SU and there is no need to adjust them...

do you have standard 'Case Aware' OS X install?

there are some 'Ruby Console' checks you can do if fresh copies still fail...

john

Hi John, thank you for the quick reply!

I've the last version of SU-Make (16.1.1451) with some days of Pro evaluation still active (downloaded from SU website several times to be sure).

I've tried removing the Plugins directory, and it reinstall the plugins, but still the error is there (only this specific plugin complains...)

About OSX install, I've a normal "File System Personality: Case-sensitive Journaled HFS+" OSX install, yes

can you guide me to make some ruby console checks?

thank you!
Filippo

Hi all,
a blocking bug, very easy to replicate.

I've tried several installations of SketchUp Make on Macbook pro.
New mac, just installed, working perfectly.
From the 1st installation (so it should be easy to replicate) this error appear at launch:

Error Loading File /Users/phy/Library/Application Support/SketchUp 2016/SketchUp/Plugins/su_sandbox/sandboxmenus.rb
Error; #<Errno;;ENOENT; No such file or directory - >

I tried giving more permission to Plugin files/dirs, I tried to remove the extension and reinstall from Extension Warehouse, I tried uninstalling completely SU and reinstall from scratch, I tried looking into files of the plugin, I searched hours in Internet for a similar problem...... don't know what to do now: sandbox is not working, and it's a very important part of Sketchup for landscapes...

any help appreciated (I'm IT programmer, so I can help to identify the issue even with more geek suggestions )
thank you,
Filippo
