This would be a problem for https://github.com/rogpeppe/godef then, because the error is actually coming from godef.

ok,thanks for your help; but it looks like dosen't been maintained anymore

[bhcleek]

Yes, godef is old and the community has mostly moved on from it. I'd recommend changing your g:go_def_mode setting to use gopls instead (see :help g:go_def_mode). Alternatively, you could fix the problem in godef and install it locally.

@BraveSoilder I just want to make sure you know that you can use gopls instead of godef for jumping to definitions. Since 'gopls' is the default value for g:go_def_mode, you can either remove let g:go_def_mode = 'godef' from your .vimrc or you can change it to let g:go_def_mode = 'gopls' to start using gopls instead. You'll find that gopls is faster than godef.
