[PyFeyn] Installation error

[Jiang-Hao Yu]

Hello Georg,

Thanks very much for your kind reply. I installed hepnicenames.sty according to the instruction in heptex. However, I got the same error message as before. 

According to the error message, it seems it due to the tex problem in pyx. I could be wrong. Any further suggestion? 

Thanks again.
Best regards,
Jiang-Hao
