执行createPeerAdminCard.sh脚本报错，寻求技术解决方案

Hey there, let's tackle this error you're hitting when running createPeerAdminCard.sh for Hyperledger Fabric. That weird @package_branch_alias_version@ placeholder and the beta2 version mismatch are the main culprits here—here's how to fix it step by step:

• Set the matching FABRIC_VERSION explicitly
  The script defaults to hlfv11, but your Composer version (1.0.0-beta2) isn't compatible with that. For Composer 1.0.0-beta2, you need to use hlfv1. Run this command before executing the script:

  export FABRIC_VERSION=hlfv1
  

• Fix the Composer version placeholder issue
  The @package_branch_alias_version@ means the script isn't pulling the correct Composer version properly. Manually specify the exact version you're using:

  export COMPOSER_VERSION=1.0.0-beta2
  

• Adjust the startup timeout (optional but recommended)
  The script assumes a 15-second timeout, but Fabric sometimes takes longer to spin up. Increase this to avoid timing out during setup:

  export FABRIC_START_TIMEOUT=30
  

• Re-run the script
  With all variables set correctly, execute the script again:

  ./createPeerAdminCard.sh
  

• Verify the admin card was created
  After running the script, confirm the card exists with:

  composer card list
  

  You should see a card named PeerAdmin@hlfv1 listed if everything worked.

Extra Tips #

• Make sure your Composer CLI version matches the one specified. If not, reinstall it with:

  npm install -g composer-cli@1.0.0-beta2
  

• Double-check that all Fabric containers are running before running the script. Use docker ps to confirm you see containers for orderer, peer, couchdb, and certificate authority.
