Could not find the 'blockdiag', 'blockdiag3' executable in PATH (Windows)

[ioannisstavrakakis]

I would need to know where you have blockdiag installed, what the value of the PATH environment variable is, and what the exact filename of the blockdiag executable is, including the extension. When running asciidoctor-pdf -r asciidoctor-diagram --trace test.adoc in Windows, I get the following error:

asciidoctor: ERROR: test.adoc: line 248: Failed to generate image: Could not find the 'blockdiag', 'blockdiag3' executable in PATH;add it to the PATH or specify its location using the 'blockdiag' document attribute

User variable PATH: C:\Python311\Lib\site-packages\blockdiag System variable PATH: C:\Python311\Lib\site-packages\blockdiag

This is where blockdiag is installed:

I can also see this folder, C:\Python311\Lib\site-packages\blockdiag-3.0.0.dist-info:

There doesn't seem to be an executable wrapper anywhere. That's what the diagram code is looking for. I don't have a Windows installation to test this on myself, but could you check elsewhere in the python install dir if there's a .exe wrapper for blockdiag somewhere?

I unisntalled and reinstalled it, and now I notice this error message during installation:

Based on https://github.com/pypa/pip/issues/9023 you need to install as a user with Administrator privileges

Yes, that did the trick! Many thanks!
