hyperledger-fabric - super 货币的fabcar.go链代码不接受更改和修改，并且始终运行先前的chaincod

我是Hyperledger Fabric的新手，安装了所有前提条件，并且Hyperledger Fabric fabcar链代码正确运行，但是当我在hyperledger fabic链代码中更改fabcar.go并运行它时，将显示旧车并且不接受任何更改。

我读过类似的问题，但答案尚不清楚，请详细告诉我如何删除先前的链代码并安装我在sample-fabric/chaincode/fabcar/go/fabric.go中编写的新链代码

请帮助我，我将非常感激自3天以来一直陷入这个问题。

以下是startFabric.sh文件中的代码

最佳答案

如果您想通过更改fabcar.go链码上的参数来与“fabcar”链码进行交互，则首先您必须停止网络，然后删除所有先前的网络模块，然后输入fabcar.go文件，更改汽车列表，然后重新建立网络，它应该将旧车列表更改为最新的。为此，您有2个选择:

1)创建teardown.sh脚本文件:

$teardown.sh (script file source code)
set -e
#Shut down the Docker containers for the system tests.
docker-compose -f docker-compose.yml kill && docker-compose -f docker-compose.yml
down
# remove chaincode docker images
docker rmi $(docker images dev-* -q)

2)删除节点模块，并修剪docker卷:

$cd...fabric-samples/fabcar/javascript
$rmdir node_modules
$docker stop $(docker ps -a -q)
$docker rm $(docker ps -a -q)
$ docker volume prune
$cd...fabric-samples/fabcar
$startFabric.sh
$cd...fabric-samples/fabcar/javascript
$npm install -g
$node query.js
