I can get an old version of wails installed if you don't use GO111MODULE, but apart from that, it seems to work ok?

I've managed to reproduce. This only happens if GO111MODULES is not set. Please install as per the installation instructions and you should be good. I will get master patched though so thanks for raising it.

[leaanthony]

This should now work as before. Please test and let us know 👍

[conanchen]

thanks @leaanthony ,

exactly,
I put " export GO111MODULE=on " in .bash_profile and it works now.

Nice one. Master is also fixed so happy days 😃
