我正在尝试运行以下设置
./createPeerAdminCard.sh
但它会引发以下错误：
> Development only script for Hyperledger Fabric control
Running 'createPeerAdminCard.sh'
FABRIC_VERSION is set to 'hlfv12'
FABRIC_START_TIMEOUT is unset, assuming 15 (seconds)
Cannot use v0.16.2 version of composer with fabric 1.2, v0.20 or higher is
required
我尝试卸载并重新安装作曲家，但仍然无法正常工作。
