minimum presenterm-export version (0.2.0) not met

[mocdaniel]

I just installed presenterm, tmux, and presenterm-export and tried to export my presentation via presenterm -e presentation.md, however the following error message is being raised:

minimum presenterm-export version (0.2.0) not met.

pip list lists presenterm-export at 0.2.0, presenterm is at 0.4.0, installed via cargo install presenterm.

Hmm interesting. What OS are you using? What output do you get if you run presenterm-export --version?

[mocdaniel]

I'm on MacOS Sonoma 14.2.1, Apple Silicon. This doesn't look good though:

➜ presenterm-export --version

Additionally, ctypes.util.find_library() did not manage to locate a library called 'pango-1.0-0'

I installed presenterm-export via pip install, the way it is mentioned in the docs.

[mfontanini]

Looks like weasyprint has dependencies outside of what they require via pip. If you install pango and whatever else dependency it complains about, does it work?

[mocdaniel]

After installing pango via homebrew install pango, I get the following exception when exporting from iTerm2 now - would you like me to open a new issue?

Yeah if you could create an issue providing details that'd be great. If you could provide a presentation file that reproduces the issue (including images) that'd help a lot.

[mocdaniel]

Will do. Thx for sorting this one out.

[mfontanini]

Np, I'll make a note to add some notes on this in the docs.
