If you are using lsp-installer you need to export the PATH
check this: https://github.com/ray-x/go.nvim#integrate-with-nvim-lsp-installer
And also make sure you are using the latest version.

I pushed another version to fix this issue.
I am not a lsp-installer user. If you still seeing issues, please add a minimum vimrc for me to reproduce. Thanks!

[WaveYourHands]
