Error when using asypictureB package

Question

After seeing this answer, i tried to draw a bond withe 2 colors using the cylinder connectors like this image:

So I used the given code but i get error (i used Texstudio and Texmaker).

@quark67 I still have the same errors.

This is screenshoots of all my steps:

1- When i choose Build & View, i get:

2- When i choose Tools ▶︎ User ▶︎ 1:Asypicture:

I get this errors :

@quark67 yes i am on windows 10 and this is my sitting page:

Answer 1

In TeXstudio, create the file with the code and name it for example test-crystal.tex.

Go to the TeXstudio settings, and choose Buid. Then click on the + Add button:

You will see:

In (1) write for example: Asypicture

In (2), write: txs:///pdflatex/[--shell-escape].

Then click on the button OK (at bottom right of the setting window in the Mac version) to validate the change.

Then choose Tools ▶︎ User ▶︎ 1:Asypicture.

Wait few seconds, then you will see:

And a bunch of files in the directory of the test-crystal.tex file. In these files, the .pdf file (yes there is also a file named test-crystal-crystal_errors.txt but here it is blank):

And it contain what you expect:
