Problem with installing using tutorial

Hello, I installed qtpyVCP using tutorial on the web. When I tried to install "make html", I got error:
Then I found in internet solvement:
After installing python I got next error
Should I install python3, maybe?

And also after all procedure of installemt I got error of one plugin, as I wrote in that topic

PS
I want to thank Kurt Jacobson, that made so nice tool for GUI development so easy. Very Grate Job!!!

I moving forward in tutorial and now it seems that I found some Bug. Before this time everythnk was fine.
I work under lesson about offsets and I need to add grid and to expand it to frame

But I "Lay out > Lay out in a grid" is inactive.
And also in the next page I see some strange "stop" subIcon near "jcodebackplot" as in the next picture

How to solve this problem? And what problem is about?

Happy New Year to all members!!!

I get to Offset tutorial

See there a little mistake in G-code

The reason the layout menu options are disabled is there is already a layout set.
You can tell this because all the layout options are disabled, but the break layout option is enabled.
You will need to break the previous layout before you can apply a new layout.

The subicon on the object browser means that that item does not have any layout set yet.

Thanks for noticing the typo in the offsets tutorial, I will fix it.

Happy new year!

Cheers,
Kurt

Thanks KCJ, it helps me.

Now I try to add some picture to my GUI.
I use "label" and try to add picture with 2 ways:
1) Press Right button on label > richt text > chouse picture icon > chouse picture from added to resource.
2) In stylesheet I shouse add resources > background-image: url(:/images/help_stone.png); (or image also tried)
I use codeand I see picture in QT Designer but doesn't see in linuxcnc.

When I ../images/help_stone.png I doesn't see picture even in QT Designer.

Also I want to use some integer/float values in G-code, I want to read from GUI and to write to my GUI. What tool should I use and how to call it or to connect to variable?
I used PyVCP in the past, it was easy to use.
