fabric网络中的报错（一）

重要声明 ，早期写的博客，后面发现里面的某些解决办法是错误的，看个开心就好 ，我也懒得改。 #

报错一： #

Error: Could not assemble transaction, err Proposal response was not successful, error code 500, msg error starting container: error starting container: Post http://unix.sock/containers/create?name=dev-peer0.org2.example.com-mycc-1.0: dial unix /host/var/run/docker.sock: connect: no such file or directory

问题原因 #

此问题是由适用于macOS的Docker Desktop的较新版本引起的。

要解决此问题，请在Docker Desktop首选项中，取消选中该框Use gRPC FUSE for file sharing， 以使用旧版osxfs文件共享，然后单击**Apply****＆**Restart

报错二： #

image

问题原因： #

环境配置问题，进入go.mod文件 重新配置

报错三： # 

An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

问题原因 #

Docker 有时候有问题。重启一下 就行

报错四： # 

Unable Initizlize SDK,failed to save channel: create channel failed: create channel failed: SendEnvelope failed: calling orderer 'localhost:7050' failed: Orderer Server Status Code: (400) BAD_REQUEST.

查看order 节点日志显示：

Principal deserialization failure (MSP student.trace.com is unknown) for identity 0

问题原因： #

我的问题是两个文件的MSPID 不一致导致的

config.yaml 文件

organizations:
  student:
    # configtx.yaml organizations -> ID
    mspID: student.tarce.com

    cryptoPath: /Users/tianzhiwei/go/src/LibrarySystem/conf/crypto-config/peerOrganizations/student.trace.com/users/{username}@student.trace.com/msp
    peers:

试着将peer-base.yaml 文件中

- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=${COMPOSE_PROJECT_NAME}_byfn 
注释掉了  具体有没有用还在测试中

问题六： #

问题二的另一种现实 # 

Unable to install and instantiate the chaincode: failed to instantiate the chaincode: instantiateOrUpgradeCC timed out or cancelled

解决办法： #

尝试一： # 

根据大佬指点，在docker-compose.yaml文件中加入一下代码  注意：每个容器后面都加这个代码
    extra_hosts:
      - "orderer.trace.com:192.168.1.255"
      - "peer0.student.trace.com:192.168.1.255"
      - "peer1.student.trace.com:192.168.1.255"
      - "peer0.library.trace.com:192.168.1.255"
      - "peer1.library.trace.com:192.168.1.255"
    networks:
      - ZFW_suyuan

尝试结果：

重新出现新的错误，idea现实错误为：
Unable to install and instantiate the chaincode: failed to instantiate the chaincode: instantiateOrUpgradeCC timed out or cancelled
docker 容器日志出现的错误为：

问题八： #

解决办法： #

不知道是什么原因，估计脑子有病

命令 docker ps 查看 并没有容器在运行

docker images 显示又正常，没有需要删除的镜像

最后将docker 重新启动了一下，它就好了 好了 就这么神奇 垃圾玩意儿

问题九： #

Unable to initialize the Fabric SDK: failed to create SDK: failed to create identity manager provider: failed to initialize identity manager for organization: material: Either a cryptopath or an embedded list of users is required

无法初始化Fabric SDK：无法创建SDK：无法创建身份管理器提供程序：无法初始化组织的身份管理器：材质：需要加密路径或嵌入式用户列表

解决办法： #

。。。。

问题十： #

在进行fabric分支切换时输入git checkout v2.0.0 会出现以下类似问题：

error: pathspec ‘master’ did not match any file(s) known to git

error: pathspec ‘v1.4.4’ did not match any file(s) known to git

解决办法： #

执行：

git add .

git commit -m ‘commit add’

解决办法： #

进入Chaincode目录 安装go依赖包

go env -w GOPROXY=https://goproxy.cn,direct go env -w GO111MODULE=on go mod init 非gapath路径就加个项目名 go mod init sacc 在gopath路径下不用加项目名 go mod tidy go mod vendor go env -w GO111MODULE=off
