docker - 尝试实例化Commercial Paper智能合约，启动容器/host/var/run/docker.sock时出错:connect:无此类文件或目录

Question

我正在使用带有IBP扩展名的HF 1.4.9和VS Code 1.39.2。在MacOS Catalina上运行的Docker 19.03.13版本。与我一起执行同一实验且具有不同操作系统的其他几个人遇到了完全相同的错误。
这是命令:docker exec cliMagnetoCorp peer chaincode instantiate -n papercontract -v 0.0.3 -l node -c '{"Args":["org.papernet.commercialpaper:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"在MagnetoCorp终端窗口中的输出为:

在监视日志终端窗口中，出现以下错误:

因此，我能够解决它。在Docker版本中，默认情况下已启用“使用gRPC FUSE进行文件共享”。取消点击，重新启动我的环境。我拆解了所有内容，然后重新创建并能够实例化。这就是导致我找到解决方案的原因https://jira.hyperledger.org/browse/FAB-18134 https://github.com/docker/for-mac/issues/4955
