Installing buffalo with GO111MODULE results in go get: error loading module requirements

I am getting an error when trying to install buffalo.

I tested with a clean GOPATH with nothing in it on go version go1.12.7 linux/amd64. GO111MODULE ist set to on.

I try to install buffalo with the command given on the website:

go get -u -v github.com/gobuffalo/buffalo/buffalo

Executing the command results in return code 1 and the error message on the end of the verbose output seems to be go get: error loading module requirements.

Solution

Try without the -u. This works for me:

$ cd $(mktemp -d)
$ go mod init example.com/tempmod
$ go get github.com/gobuffalo/buffalo/buffalo

Do those steps work for you?

Some more on -u from the modules wiki:

A common mistake is thinking go get -u foo solely gets the latest version of foo. In actuality, the -u in go get -u foo or go get -u foo@latest means to also get the latest versions for all of the direct and indirect dependencies of foo. A common starting point when upgrading foo is instead to do go get foo or go get foo@latest without a -u (and after things are working, consider go get -u=patch foo, go get -u=patch, go get -u foo, or go get -u).

Also, with your original command, you were very likely seeing a more specific error earlier in the output. If you run without -v to reduce the noise and then ignore the "finding", "downloading", and "extracting" messages, there is probably a more specific error there.
