Re: [PyX-user] Hello World blows out

Dear Donald,

are you aware that you need a TeX installation? Like texlive (https://www.tug.org/texlive/)

Trying to simulate what happens without TeX being available, I just changed the name of the tex executable in my .pyxrc. The result looks a bit different, but still ... I think this could be the source of your problem.


Best,


André

Hi folks,

I'm trying PyX for the first time.  This is on an iMac, High Sierra, 10.13.6.

The third line of the Hello World demo blows out with this error:

Perhaps there's some secret step I've missed?

Thanks!
