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

Question

我正在遵循 Hyperledger 的教程 1 并设置 Fabric 环境。我安装了正确版本的所有正确依赖项。我的 docker 版本是 19.03.1，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 图像。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

一开始我认为我需要设置更好的权限，所以我允许 docker 在没有 sudo 的情况下运行，但仍然出现相同的错误。我已经使用 Hyperledger 的 First-Network 和 Fabcar 教程成功运行了 docker 映像，但无法让区块链平台启动它。这是整个日志。

这里是教程的链接，虽然它显示在 VScode https://developer.ibm.com/tutorials/ibm-blockchain-platform-vscode-smart-contract/ 中。我一直跟踪到您启动 docker 图像的地步。

Answer 1

显示权限错误，当前用户无法访问docker引擎

运行这个命令，需要在你的 shell 中定义 $USER

sudo usermod -aG docker $USER

然后授予访问权限

sudo chmod 777 /var/run/docker.sock
