Hyperledger Cannot compile chaincode cannot find package error

Question

Hi I am trying to running Hyperledger chain code on MAC. When I try to compile the code, 

cd $GOPATH/src/github.com/chaincode1

go build

i am getting error:

chaincode1.go:30:2: cannot find package "github.com/hyperledger/fabric/core/chaincode/shim" in any of: /usr/local/Cellar/go/1.7.1/libexec/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOROOT) ($GOPATH not set)

Comments

Please run the below command and tell what output you get:

$ echo $GOPATH

Hi @Tina. I am facing the same issue. I don't see any output when I run this command.

Seems like GOPATH is not set. You have to set the GOPATH as follows:

Find where you have installed go lang. 

$ whereis go

Export using the following command:

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

As the error says, it cant find the source code on the local system. You have to have the source on your system. You can solve this error as follows:

$ cd $GOPATH/src/github.com
$ mkdir hyperledger
$ cd hyperledger
$ git clone http://gerrit.hyperledger.org/r/fabric.git

I already did what you said but i am still getting the same error my go path  $home/work the fabric is cloned into

$home/work/src/github.com/hyperledger

the chaincode is in $home/work/fabric-sample/chaincode/sacc

i also have another chaincode in

$home/work/src/chain/mediuchaincode

i can not compile any  of them , when i try go get it give me this

package github.com/hyperledger/fabric/core/chaincode/shim: cannot find package "github.com/hyperledger/fabric/core/chaincode/shim" in any of:

/usr/local/go/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOROOT)

/home/shovon/work/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOPATH)

Hope this helps!

You will need to get following go libraries to compile chaincode locally.

go get github.com/hyperledger/fabric/protos/peer
go get github.com/hyperledger/fabric/core/chaincode/shim

These libraries will be installed under GOPATH, make sure it is set.

In case if you get any(specific to context and plugin) errors for "go get" command , then follow the procedure mentioned below to resolve.

Upgrade to latest version of GO.

sudo apt-get purge golang*

sudo rm -rf /usr/lib/go-1.6/ /usr/lib/go-1.6/src/ /usr/lib/go-1.6/src/runtime/ /usr/lib/go-1.6/src/runtime/race

curl -O https://storage.googleapis.com/golang/go1.11.1.linux-amd64.tar.gz

sudo tar -C /usr/local -xzf go1.11.1.linux-amd64.tar.gz

mkdir -p ~/go; echo "export GOPATH=$HOME/go" >> ~/.bashrc

echo "export PATH=$PATH:$HOME/go/bin:/usr/local/go/bin" >> ~/.bashrc

source ~/.bashrc

Then

go get github.com/hyperledger/fabric/core/chaincode/shim
go get github.com/hyperledger/fabric/protos/peer

Answer 3

Follow the process:

$ mkdir -p $GOPATH/src/github.com/hyperledger
$ cd $GOPATH/src/github.com/hyperledger
$ git clone -b release-1.2 https://github.com/hyperledger/fabric.git

Hi @Pavan. Tried this, still getting the same error. Any other way to solve this?

Answer 4

I had the same problem. I solved it by setting gopath location for go projects. Then when I ran the commands, this error was gone.
