1. 问题描述
下载Hyperledger Fabric镜像时候，执行语句
sudo curl -sSL http://bit.ly/2ysbOFE | bash -s 1.4.0
出现如下错误
===> List out hyperledger docker images
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/json: dial unix /var/run/docker.sock: connect: permission denied
2. 解决方案
赋予当前用户docker sudo权限
~$ echo $USER
~$ sudo usermod -aG docker your_username
注：新开启一个终端！！！ ，再次下载Hyperledger Fabric镜像时候，执行语句如下
sudo curl -sSL http://bit.ly/2ysbOFE | bash -s 1.4.0
问题解决
