Question

我在GitHub（https://github.com/IBM-Blockchain/learn-chaincode）中关注Bluemix Blockchain教程学习链代码，但在初始构建时失败了。

错误消息是：

/d/work/src/github.com/learn-chaincode/start (master)
$ go build ./
chaincode_start.go:23:2: cannot find package "github.com/hyperledger/fabric/core/chaincode/shim" in any of:
        D:\opt\Go\src\github.com\hyperledger\fabric\core\chaincode\shim (from $GOROOT)
        D:\work\src\github.com\hyperledger\fabric\core\chaincode\shim (from $GOPATH)

我按照设置环境的初始设置进行了操作：

$ go get github.com/hyperledger-archives/fabric/tree/v0.5-developer-preview/core/chaincode/shim
package github.com/hyperledger-archives/fabric/tree/v0.5-developer-preview/core/chaincode/shim: cannot find package "github.com/hyperledger-archives/fabric/tree/v0.5-developer-preview/core/chaincode/shim" in any of:
        D:\opt\Go\src\github.com\hyperledger-archives\fabric\tree\v0.5-developer-preview\core\chaincode\shim (from $GOROOT)
        D:\work\src\github.com\hyperledger-archives\fabric\tree\v0.5-developer-preview\core\chaincode\shim (from $GOPATH)

结果是它填充了目录hyperledger-archives。

$ ls $GOPATH/src/github.com/hyperledger-archives/fabric/
bddtests/        docs/      LICENSE          peer/      sdk/
consensus/       events/    MAINTAINERS.txt  protos/    tools/
CONTRIBUTING.md  examples/  Makefile         pub/       TravisCI_Readme.md
core/            gotools/   membersrvc/      README.md  vendor/
devenv/          images/    mkdocs.yml       scripts/

但是你可以看到没有D：\ work \ src \ github.com \ hyperledger-archives \ fabric \ tree。

我做错了什么？

确保Hyperledger Fabric位于GOPATH目录中可以解决此问题。 Learn Chaincode教程（https://github.com/IBM-Blockchain/learn-chaincode）引用了先决条件“Chaincode Development Environment”部分：https://github.com/IBM-Blockchain/learn-chaincode/blob/v1.0/docs/setup.md

“Chaincode Development Environment”部分的“Instructions”标题提到的错误几乎与观察到的以下错误相同。

    $ go build ./
    chaincode_start.go:23:2: cannot find package "github.com/hyperledger/fabric/core/chaincode/shim" in any of:
    D:\opt\Go\src\github.com\hyperledger\fabric\core\chaincode\shim (from $GOROOT)
    D:\work\src\github.com\hyperledger\fabric\core\chaincode\shim (from $GOPATH)

错误的原因可能是在GOPATH中没有正确安装Hyperledger Fabric。
