在 Hyperledger Fabric 2 中部署链码时出错答案

【问题标题】：Error deploying chaincode in Hyperledger Fabric 2在 Hyperledger Fabric 2 中部署链码时出错

我正在尝试部署链代码：

超级账本结构 2
Ubuntu 20.04

go 版本 go1.13.8 linux/amd64

我总是收到这个错误：

我不知道为什么会出现这个问题。我一直在网上阅读，并没有明确的解决方案......

有什么想法吗？

谢谢

我把它作为评论留下了，但版本有问题。

In particular, unlike 1.13, the vendering behavior is different from version 1.14 (>higher), and this seems to be a problem due to this process. – myeongkil kim

安装方法有问题是没有意义的。你在问题中说你已经安装了 go1.13.8 linux/amd64 版本。如果环境变量设置好，官方go可以正常运行，那么根据安装方式执行不同是没有意义的。

添加到， I don't think the problem was Go version, but the way of installing Go (at least in Ubuntu). – AlexAcc 如果您认为版本不是问题，我想知道为什么。
您可以非常简单地检查它。这是一种在同一环境中只更改版本的方法。

所以我实际运行了它，我能够像这样确认版本问题是正确的：

去 1.13.8

# same environment
wget https://golang.org/dl/go1.13.8.linux-amd64.tar.gz
sudo tar -xvf go1.13.8.linux-amd64.tar.gz
sudo mv go /usr/local
go env

cd $GOPATH/src/github.com/hyperledger/fabric-samples/test-network
./network.sh down
./network.sh up
./network.sh deployCC

去 1.15.6

sudo tar -xvf go1.15.6.linux-amd64.tar.gz

【解决方案2】：

我通过删除容器和卷解决了这个问题：

-使用以下命令停止容器：docker-compose down。

-使用以下命令删除所有容器：docker rm -f $(docker ps -a -q)

-使用以下命令删除所有卷：docker volume rm $(docker volume ls -q)

警告：上面的命令将删除所有容器/卷，而不仅仅是 Fabric 创建的那些

【解决方案3】：

问题是我使用的是 go，安装了：

apt get

及以后：

apt install

但是直到我尝试使用 wget 从官方来源下载 go 时它才起作用：

wget https://golang.org/dl/go1.15.6.linux-amd64.tar.gz
sudo tar -xvf go1.15.6.linux-amd64.tar.gz
sudo mv go /usr/local
sudo echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc

【讨论】：

需要更准确的分析和解释。问题似乎不是别的，而是 go 语言的一个版本。
特别是，与1.13不同的是，vendering行为与1.14版本不同（>更高），这似乎是由于这个过程造成的问题。
我认为问题不在于 Go 版本，而是安装 Go 的方式（至少在 Ubuntu 中）。
我不知道为什么我说这不是版本问题。我需要一个解释。

【解决方案4】：

安装较新版本的golang 并运行命令后： sudo echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc 为了更新$PATH 变量，我必须关闭并重新打开wsl 命令提示符。

在成功部署该链代码之后。
