The core error is :

compile: version "go1.14.2" does not match go tool version "go1.14"

Environment

MacOS 10.14
Golang go version go1.14 darwin/amd64

Reason

There are two golang versions in my system, we can verify as follows:

➜ /usr/local/go/bin/go version
go version go1.14.2 darwin/amd64

➜ /usr/local/Cellar/go/1.14/libexec/bin/go version
go version go1.14 darwin/amd64

So the problem is located.

Solution

We should change our GOROOT to the 1.14 version of go in my system, e.g. /usr/local/Cellar/go/1.14/libexec

Open .zshrc in my system, and change the GOROOT environment settings as follows:

export GOROOT=/usr/local/Cellar/go/1.14/libexec

Retart the terminal , and verify the go version as follows:

➜  ~ echo $GOROOT
/usr/local/Cellar/go/1.14/libexec
➜  ~ go version
go version go1.14 darwin/amd64
➜  ~ which go
/usr/local/bin/go
➜  ~ ls -l /usr/local/bin/go
lrwxr-xr-x  1 bswen  admin  24 Dec 14 20:36 /usr/local/bin/go -> ../Cellar/go/1.14/bin/go
➜  ~

Re-execute the command :
