Re: [PyX-user] Hello World blows out

[André W. <co...@wo...>]

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
