Unable to install bleve, cannot find package "github.com/blevesearch/zap/v11" in any of

Question

I cannot install bleve as it complains about zap:

go get github.com/blevesearch/bleve/...

package github.com/blevesearch/zap/v11: cannot find package "github.com/blevesearch/zap/v11" in any of:
    /usr/local/go/src/github.com/blevesearch/zap/v11 (from $GOROOT)
    /home/w/go/src/github.com/blevesearch/zap/v11 (from $GOPATH)
package github.com/blevesearch/zap/v12: cannot find package "github.com/blevesearch/zap/v12" in any of:
    /usr/local/go/src/github.com/blevesearch/zap/v12 (from $GOROOT)
    /home/w/go/src/github.com/blevesearch/zap/v12 (from $GOPATH)
package github.com/blevesearch/zap/v13: cannot find package "github.com/blevesearch/zap/v13" in any of:
    /usr/local/go/src/github.com/blevesearch/zap/v13 (from $GOROOT)
    /home/w/go/src/github.com/blevesearch/zap/v13 (from $GOPATH)

I can fetch it via gopkg.in/blevesearch/zap.v13, but bleve itself is referencing this. My GOPATH is unset.

I was having the same problem and found that bleve now requires using of Go modules to be enabled. I see, in your env, that Go module (GO111MODULE) is not enabled. You need to enable Go module by adding this line in your .bashrc (or equivalent) file.

export GO111MODULE=on

Or you can use it directly in command when installing bleve.

GO111MODULE="on" go get -u github.com/blevesearch/bleve/...

But, if you use it in command line and do not put in your .bashrc file, you may need to use it when go run or go build. So it will be helpful to add it to .bashrc.
