Sample Response:

Your system is ready to brew.

4. Now install mockery 

brew install mockery

or for Apple Silicon

Troubleshooting Guide for Blobbers Setup (Mac M1 or M2)

If blobbers and validators containers are not coming up while doing local setup, then you can try these steps:

  • You can try removing wallet.json file from ~/.zcn directory and recreate a wallet by using ./zwallet create-wallet command. Copy the client_id generated from here and paste in delegate_wallet: <your_new_client_id> in 0chain_blobber.yaml and 0chain_validatory.yaml files present at blobber/config directory.

  • Also, check if block_worker is set to http://198.18.0.98:9091/ in both of the above files.

  • Stop the sharders and miners containers and restart them. First start the sharder and when it is ready (try hitting the localhost:7171 to test) then start the miner.

  • Now start the blobbers and validators.

  • If you are on Mac M1. You need to start blobbers and validators by running the cli.sh script from this folder. This is an interactive script. When you run it, you need to provide input for what you need to do. Follow these:

    1. Create a postgres db by pressing 1 and then again 1.

    2. Create a blobber by running the script again and press 1 and then 2.

    3. If the step2 works, start a new terminal window and run the script again, and press 1 and then 3 to start the validator.

    4. Repeat steps 2 and 3 to start multiple blobbers and validators by following the interactive cmd line.
