“unrecognized import path” with go get

问题:

I'm trying to install a web.go, but running go get github.com/hoisie/web returns

package bufio: unrecognized import path "bufio"
package bytes: unrecognized import path "bytes"
package crypto/rand: unrecognized import path "crypto/rand"
package crypto/sha1: unrecognized import path "crypto/sha1"
package crypto/tls: unrecognized import path "crypto/tls"
package encoding/base64: unrecognized import path "encoding/base64"
package encoding/binary: unrecognized import path "encoding/binary"
package encoding/json: unrecognized import path "encoding/json"
package errors: unrecognized import path "errors"
package fmt: unrecognized import path "fmt"

and this continues for a while with various packages, before returning nothing else. go env gives me:

GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH=""
GORACE=""
GOROOT="/home/me/go"
GOTOOLDIR="/home/me/go/pkg/tool/linux_amd64"
TERM="dumb"
CC="gcc"
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"
CXX="g++"
CGO_ENABLED="1"

How can I install web.go? Using go get (rather than go install) is what is in the README on the github page. My Go version is go version go1.2 linux/amd64.

回答1:

The issues are relating to an invalid GOROOT.

I think you installed Go in /usr/local/go.
So change your GOROOT path to the value of /usr/local/go/bin.

It seems that you meant to have your workspace (GOPATH) located at /home/me/go.

This might fix your problem.
Add this to the bottom of your bash profile, located here => $HOME/.profile

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin

Make sure to remove the old references of GOROOT.

Then try installing web.go again.

If that doesn't work, then have Ubuntu install Go for you.

sudo apt-get install golang

I installed Go with brew on OSX 10.11, and found I had to set GOROOT to:

/usr/local/Cellar/go/1.5.1/libexec

(Of course replace the version in this path with go version you have)

Brew uses symlinks, which were fooling the gotool. So follow the links home.

I had exactly the same issue, after moving from old go version (installed from old PPA) to newer (1.2.1) default packages in ubuntu 14.04.

The first step was to purge existing go:

sudo apt-get purge golang*

Which outputs following warnings:

dpkg: warning: while removing golang-go, directory '/usr/lib/go/src' not empty so not removed
dpkg: warning: while removing golang-go.tools, directory '/usr/lib/go' not empty so not removed

It looks like removing go leaves some files behind, which in turn can confuse newer install. More precisely, installation itself will complete fine, but afterwards any go command, like "go get something" gives those "unrecognized import path" errors.

All I had to do was to remove those dirs first, reinstall golang, and all works like a charm (assuming you also set GOPATH)

# careful!
sudo rm -rf /usr/lib/go /usr/lib/go/src
sudo apt-get install golang-go golang-go.tools

回答4:

Because GFW forbidden you to access golang.org ! And when i use the proxy , it can work well.

you can look at the information using command go get -v -u golang.org/x/oauth2

I had the same problem on MacOS 10.10. And I found that the problem caused by OhMyZsh shell. Then I switched back to bash everything went ok.

Here is my go env

bash-3.2$ go env
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/bis/go"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1

回答6:

I had the same issue after having upgraded go1.2 to go1.4.

I renamed src to _src in my GOPATH then did a go get -v

It worked then I deleted _src.

Hope it helps.

回答7:

I had a similar problem. But that was just because the package I was installing is not in the $GOPATH/src/ directory, when I installed in that directory everything worked fine (except the package name is different caused problem, but I used Makefile to build so that may not be relevant to your problem).

回答8:

I encountered this issue when installing a different package, and it could be caused by the GOROOT and GOPATH configuration on your PATH. I tend not to set GOROOT because my OS X installation handled it (I believe) for me.

1. Ensure the following in your .profile (or wherever you store profile configuration: .bash_profile, .zshrc, .bashrc, etc):

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOROOT/bin
   

2. Also, you likely want to unset GOROOT, as well, in case that path is also incorrect.

3. Furthermore, be sure to clean your PATH, similarly to what I've done below, just before the GOPATH assignment, i.e.:

   export PATH=$HOME/bin:/usr/local/bin:$PATH
   export GOPATH=$HOME/go
   export PATH=$PATH:$GOROOT/bin
   

4. Then, source <.profile> to activate

5. retry go get

回答9:

The most common causes are:
1. An incorrectly configured GOROOT
OR
2. GOPATH is not set
