Air doesn't work with errors related to github.com/imdario/mergo

[tomcat1986]

Hi!
I got the following error and it didn't work when I tried to build docker.
I hypothesize that the error is due to a URL change in ver 1.0.0 of github.com/imdario/mergo, but I'm having trouble coming up with a solution...
(https://github.com/imdario/mergo/releases/tag/v1.0.0)

Does anyone have a suggestion for a solution?

Dockerfile

FROM golang:1.18

RUN go get -u github.com/cosmtrek/air@latest

@imdario
Thank you for trying it!
After seeing your error statement and changed the code as follows, it worked!

before

RUN go get -u github.com/cosmtrek/air@latest

after

RUN go install github.com/cosmtrek/air@latest

[pierreneter]

go: github.com/imdario/mergo@v1.0.0: parsing go.mod:
        module declares its path as: dario.cat/mergo
                but was required as: github.com/imdario/mergo

what should we do?
update github.com/imdario/mergo to dario.cat/mergo in air source code?

@pierreneter A workaround is to clone air repository and run go install ./... from it.

I had this error too trying to get Air just now. Reading this thread and a little more, I was able to install it with:

sudo GOBIN=/usr/local/bin/ go install github.com/cosmtrek/air@latest
