@xmapst 对不起，我不会说中文，所以我用英语继续。

Go interpreter mode uses yaegi library which has problems running zap package (which your package use under the hood).

I'll try to investigate the issue but can't give any promises right now.

As a temporary solution, I suggest using a server to run Go programs:

谢谢回答. 据观察应该是yaegi的局限性导致的

@xmapst

Can you please create an issue in Yaegi repository? Seems like Zap library started to use generics which Yaegi doesn't support right now (and I don't know when it will be implemented).
