I've below go version

$ go version
go version go1.14.3 linux/amd64

$ which 
/usr/local/go/bin/go

GOPATH is set as

    $ echo $GOPATH
    /home/raj/go

PATH variable is set as -

$ echo $PATH
/home/raj/.cargo/bin:/home/raj/go/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.cargo/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.cargo/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.cargo/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.sdkman/candidates/maven/current/bin:/home/raj/.sdkman/candidates/java/current/bin:/home/raj/.sdkman/candidates/gradle/current/bin:/home/raj/.cargo/bin:/home/raj/.cabal/bin:/home/raj/.ghcup/bin:/home/raj/.local/bin:/home/raj/bin:/home/raj/.cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/var/lib/snapd/snap/bin:/usr/local/go/bin:/home/raj/bin:/home/raj/Deps/cmake/3.16.5/cmake/bin/:/usr/local/go/bin:/home/raj/bin:/home/raj/Deps/cmake/3.16.5/cmake/bin/:/usr/local/go/bin:/home/raj/bin:/home/raj/Deps/cmake/3.16.5/cmake/bin/

As you can see /home/raj/go/bin is in PATH

Now, I'm trying to install gopls and I'm getting below error -

$ GO111MODULE=on go get -v golang.org/x/tools/gopls@latest go: golang.org/x/tools/gopls latest => v0.4.1 runtime/internal/atomic

Why I'm getting this error and how can I fix this?
