Cannot import third party packages on Linux (not even the ones in the README)

According to the README, under Linux I should be able to successfully import a third-party package like gnoum.org/v1/floats like this:

gomacro> import ( "gonum.org/v1/floats" )

But this fails with:

// debug: looking for package "gonum.org/v1/floats" ...
error loading package "gonum.org/v1/floats" metadata: -: no required module provides package gonum.org/v1/floats; to add it:
        go get gonum.org/v1/floats

This behavior occurs regardless of whether or not the local directory is an existing Go project or not. There are no GO* environment variables in the local environment.

I'm using:

  • Go version: go version go1.19.4 linux/amd64
  • gomacro version 2.7 (via Fedora package gomacro-2.7-15.20210109git88cbcb5.fc35.x86_64)

Is the import functionality only available in post-2.7 versions of the code?

If I replace the packaged version of gomacro with the version installed by go install github.com/cosmos72/gomacro@latest (which gets me v0.0.0-20221020183653-9aafa23692e7), the import statement fails with:

gomacro> import ( "gonum.org/v1/floats" )
// debug: running "go get gonum.org/v1/floats" ...

That may just mean that the referenced module no longer exists; import seems to succeed with other third party modules, so perhaps the fix here is really just a doc update.

Thanks for spotting this!

Yes, it's a typo in the README: the package name should be gonum.org/v1/gonum/floats

Fixed in commit 12bd30a
