docker - IBM Blockchain Platform在VS代码中创建Fabric环境时出错

Question

我正在关注Hyperledger的教程1，并设置Fabric环境。我已经安装了正确版本的所有正确依赖项。我的docker版本是19.03.1，而docker-compose是1.8.0。在VS代码中使用IBM Blockchain Platform，当我单击Local Fabric (Click to Start时，它无法启动docker镜像。相反，它给了我一个错误Failed to start Local Fabric: Error: Failed to execute command "/bin/sh" with arguments "generate.sh" return code 126
我认为起初我需要设置更好的权限，因此我允许docker在不使用sudo的情况下运行，并且仍然出现相同的错误。我已经在Hyperledger的First-Network和Fabcar教程中成功运行了docker镜像，但是无法使用Blockchain Platform来启动它。这是整个日志。

这是本教程的链接，尽管它以VScode https://developer.ibm.com/tutorials/ibm-blockchain-platform-vscode-smart-contract/显示。我一直跟踪到您启动docker镜像的地步。

Answer 1

显示权限错误，当前用户无法访问Docker引擎
运行此命令，需要在shel中定义$ USER

sudo usermod -aG docker $USER

之后，授予访问权限

sudo chmod 777 /var/run/docker.sock
